Description:

Here is a summary of signal map. The charged particle detector includes 6 layers of Si-Pad, 1 DSSD and 1 CsI.
All these detectors are installed inside the detector pocket. All signals are connected to one PCB which is attached on the pocket, then are connected
to the PCB of the flange by high density cable. This document descripts the signal map on the PCB of the detector
pocket and flange.



The signal maps of the PCB of the detector pocket are shown as follow:

We have an EPCIS server (ioc) running on our raspberry (ext-027377). It talks to our MesyTec modules (MSCF shapers, MHV4 high-voltages).
In principal it should be running all the time, but here is the manual how to check/start it:

-login on GSI-linux using <litv-exp> user
-type in console: e121pi (alias for: 'ssh -X litv-exp@ext-027377.gsi.de')
-open the "mrcc" screen session: screen -x mrcc
-if the ioc is running you will see here terminal outputs like:

Quote:
cbLow: Active ringpi:mrcc:mhv2:getRcStatus
cbLow: Active ringpi:mrcc:mhv2:getCurrent1

-if this is not the case, you have to restart the ioc:
- <Ctrl>+c to end any running ioc (if it has errors)
- the command to start the ioc: e121_ioc (alias for '/home/litv-exp/epics/mrcc_ioc/bin/linux-arm/mrcc /home/litv-exp/epics/mrcc_ioc/iocBoot/iocmrcc/start_ringpi.cmd')
- now the terminal outputs should be as quoted above (errors show up in red)

- finally <Ctrl>+a d to exit the screen session
  5   Fri Dec 7 11:39:41 2018 Jan GloriusSlowControlGUI for remote control of MSCF+MHV4
We have a GUI for remote controlling our MesyTec modules MSCF16 and MHV4 for E121 experiment.

Here is the instructions to run it:

1. login to GSI-linux using <litv-exp> user
2. get the EPICS environment by typing in terminal: epicsfind
3. type in terminal: GUIe121 (alias for 'medm -x /u/litv-exp/E121/medm/e121.adl')

if you get the message: 'medm: command not found' you didn't load the EPICS environment (2.)

The GUI is more or less self-explaining.
Be sure to follow this procedure when changing a value (e.g. threshold for MSCF):

1. click on small text-panel with value
2. leave mouse pointer inside panel
3. change value by typing
4. press enter

  9   Tue May 28 08:36:14 2019 JanDAQMBS start & RFIO server
You need a DAQ-PC and the RIO crate computer.
All of the DAQ proceedures laid out here are operated from inside the DAQ screen session.
Right now for e121 the following DAQ-setup is used: (might change in the future)

DAQ-PC: lxg0155
screen session: e121_daq @ lxg0155
RIO: r4l-47
DAQ dir: /esr/usr/litv-exp/2019Munich-Det



The most important commands:

on DAQ-PC
mbs - start mbs DAQ
rawDispRFIO64 - start RFIO server

in MBS shell
@startup - initialize MBS (only inside DAQ dir)
@connect - connect RFIO server (only if server running)
@runstart - open file for data writing
@runstop - close file
start acq - start DAQ
show acq - status of DAQ
show file - status of current file/RFIO server




The full proceedure for the DAQ:
  • on DAQ-PC enter screen session:
    litv-exp@lxg____:~$ screen -x e121_daq
    or create new screen session if non is exisiting:
    litv-exp@lxg____:~$ screen -S e121_daq
  • inside screen: go to 1st tab (MBS) and login to RIO if not yet done:
    <Ctrl-a 0>
    litv-exp@lxg____:~$ ssh r4l-47
    
  • on RIO reset and start MBS
    R4L-47 litv-exp > cd 2019Munich-Det
    R4L-47 litv-exp > resl
    R4L-47 litv-exp > mbs
    mbs > @startup
    
  • inside screen go to 2nd tab (RFIO)
    <Ctrl-a 1>
    or create 2nd tab if not exisiting
    <Ctrl-a c>
  • start RFIO server on DAQ-PC
    litv-exp@lxg____:~$ cd /u/litv-exp/rfio
    litv-exp@lxg____:~$ ./rawDispRFIO64-wheezy
    -I- 64 bit RFIO test server (lxg0155) listening on port 1974

  13   Wed Jan 29 10:42:42 2020 ShahabGeneralGas target control with the new control system event
Many thanks to Sergey and Nikos we have tested the connection of the new control system for turning on and off of the gas target.

Connections:

For the test event machines 12 (event 162) and 14 (event 163) were chosen for gas target on and off. The old Pulzzentrale code remains unchanged on 10. The middle output of the TIF editors can then be connected to the gas target control.

The created pulses were measured on the oscilloscope and hat the duration of 1us and amplitude of 5V.

The gas target control then produces the required long pulse which comes out as a BNC connection. If in the local mode, gas target can controlled by out-on and out-off. For the above scenario, we need the event mode.

The output of the gas target control is connected to the ESR-Messhuette-Panel number 2, which goes back to Messhuete and form there to the top of ESR.


All connections are working properly until the gas target itself.

Software:

Different subchains can be activated and deactivated on demand. Also their duration can be changed on the fly, but currently a change in other settings (such as Quadrupoles) might reset the duration values to their default.

1) From SIS, 206Pb67+ @401.17 MeV/u goes to FRS where only SEETRAM is placed in the target area to strip off 206Pb67+ to get 206Pb81+.
2) There is 206Pb81+ (H-like primary beam) inside ESR at 400 MeV/u.
3) The ESR team is now trying Stochastic cooling with 206Pb81+ beam at 400 MeV/u.

1) ESR team is successful with the Stochstic cooling of primary H-like 206Pb81+ beam @400 MeV/u.
2) Now, they are trying for stacking of the beam.
  20   Fri Mar 27 13:04:17 2020 RaganGeneralFRS Settings until now
Yuri and Helmut have been extensively involved in tuning and optimizing of the FRS.

26th March, 2020 (Evening setting):
1) 206Pb67+ beam from SIS @401.17 MeV/u.
2) SEETRAM in target area of FRS is used for stripping the beam from SIS to get 206Pb81+ and is then transported to ESR @400 MeV/u. (SEETRAM consists of three Ti foils of ~10 um thickness which are used for stripping purpose (more info: https://www-win.gsi.de/frs-setup/ ))
3) SL1 slits are opened +-10 mm to get rid of other charge states of 206Pb and only transport 206Pb81+ through FRS.

27th March, 2020 (Evening setting):
1) Different target (Be 1-6 g/cm2 with Nb backing) and degrader (Al)thicknesses are used for the optimization of 206Pb81+ with matter in FRS to get the beam with @400 MeV/u in ESR.
2) 206Pb67+ beam from SIS @540-560 MeV/u.

  22   Fri Mar 27 19:51:37 2020 RaganGeneralESR Machine
By changing the tune to Qx=2.33, Qy=2.36 the momentum acceptance was significantly improved. A variation of the cooler voltage of 10300 V was possible without beam loss. That corresponds to a momentum acceptance of 2.7 %. That should provide good conditions for longitudinal stacking.

Thanks to the ESR team !
  23   Fri Mar 27 19:59:09 2020 RaganGeneralBeam stacking in ESR is achieved
Thanks to Sergey and Markus, stacking of primary H-like 206Pb81+ beam in ESR is achieved.

The stacking of the primary beam was established. There is continuous cooling on the injection orbit by stochastic cooling and by electron cooling on the stack orbit. (Time controlled operation of stochastic cooling could not be achieved due to controls issues). After stchastic cooling on the injection orbit the rf system decelerates the beam by 1.5 % in momentum and at the lower momentum electron cooling keeps the beam. The DC trafo shows accumulation of 10 injections of primary low intensity Pb81+ beam. Losses during the accumulation seems to be small.

  25   Fri Mar 27 20:52:31 2020 RaganGeneralPlans for the measurement with 206Pb81+
We plan to measure:

1. Lifetime of H-like 206Pb81+ beam with two electron cooler currents:
a) 200 mA
b) 10 mA (so that recombination rate is less)
using MWPC (capture detector in outer pocket) and CsISiPHOS (loss detector in inner pocket). 

2. To find the efficiency of the MWPC.

The ionisation (on CsISiPHOS) and capture (on MWPC) trigger rates are calculated for 206Pb81+ beam with 10^6 particles revolving in ESR ~2 MHz frequency with H2 gas jet target density ~ 10^14 particles/cm3.

XY co-relation of DSSSD showing 206Pb82+ beam hitting the CsISiPHOS detector present in the inner pocket of ESR after the first dipole after the gas jet. 206Pb82+ is 
produced by ionisation of 
206Pb81+ due to interaction of beam with the gas jet.
  28   Sat Mar 28 04:50:34 2020 RaganDetectorsMWPC
Alex and Pierre-Michel applied 1500 V to the anode and adjusted the threshold in Messhute.
x1 signal was small & noisy and rest of the signals were fine.
  29   Sat Mar 28 11:00:14 2020 Ragan, RuiJiu, Mei, Yuri, TinoDetectorsMovement of detector
10:51 am the CsISiPHOS is moved to 65 mm from 60 mm.The spot on the DSSSD is changed by 5 mm which confirms the hit of the beam.

11:05 
Detector is moved back to 60 mm.

Yuri reduces beam intensity in the ESR to reduce the countrate on the detectors.

ESR is open now
  33   Sat Mar 28 12:19:21 2020 Ragan, RuiJiuDAQChange of the polarity of Amplifiers
Since last night, the signals from the p-side of all the Si pads were seen as negative on picoscope.
The signals from DSSSD, all n-sides of Si pads and CsI were positive which all are in MSCF-5.
Thus, I and RuiJiu, changed the polarity jumpers of MSCF 1,2,3 and 4(all the four jumpers inside the mentioned MSCF) and now hope to see positive signals from the p-side of all the Si pads.
  34   Sat Mar 28 13:09:11 2020 Mei,Yury, Tino, Ragan, RuijiuGeneralShift plan
From Yury,

For now, measure the beam life time with 3 different electron current in the e-cooler,i.e. 200mA(default), 10mA, and 20mA. For each current, 4 sets of 30mins long measurements shall be taken.

Starting from 9pm Helmut and Sergey will come for setting up FRS

The HV of detector is off.
Start DAQ to record the ESR current in lmd file.
Nik is optimizing the gas jet target. So this file is still test run.
  39   Sat Mar 28 15:23:05 2020 Alex, Ragan, Mei Bai Generalbeam lifetime measurement
We see two species in the Schottky spectra during the beam lifetime measurement without the target. The one (probably the primiary beam) is significantly better cooled than the other.
So, we were wondering what is the other beam? Maybe the recombined ones?
  40   Sat Mar 28 16:09:50 2020 AlexGeneralno beam in the ESR
Ragan and Ruijiu went in the ESR for short time to fix something with the slow control of the silicon detector.

  43   Sat Mar 28 18:11:13 2020 Alex, YuriGeneralno beam in the ESR
Yuri and Sergey (on phone) have investigated extensively the problem with having no beam in the ESR. The FRS has been checked and seems OK. The ESR is fine as well.
The problem seems to be the timing. Ths SIS and the ESR seem to be completely out of synchronization. The on-call service for the control system has been called.

Yuri and Sergey are still working on optimising the Tl fragments !
  50   Sun Mar 29 13:04:32 2020 Ragan, RuiJiuRunsrun file: 1298
The Tl fragments are being stacked (almost ~20 staacks) and tried to store nicely in ESR.
The plan is to see the number of contaminants on the inner detector (CsISiPHOS) after the gas jet is on (Ar gas jet) and minimise this number for different FRS settings !!

P.S. Prayers have magical powers :) :)

In the ESR picture below, the decay of beam is very fast initially for few minutes and then the decay is constant. But why does it decay for first few minutes ?

Hi everybody,

is there now much more rate on  the detectors?

Perhaps it helps to turn down the bias for a while and to take the detectors out of the beam, by pulling the pocket out?

And then see if the leakage current comes down again.
good luck, Thomas

  103   Mon Mar 30 20:51:06 2020 RaganDetectorsBias Voltage for Si-pads
The limit of the leakage current for all Si pads was increased from 1500 nA to 5000nA and 
leakage current was recorded for different Bias Voltages (32V, 35V, 40V, 45V, 50V, 55V 
and 60V).
Since, I_leakage remains < 3 uA for 60 V, it is decided to increase the Bias Voltage for 
all the Si-pads from 32 V to 60 V.
For DSSD and CsI, bias voltages remains same (-50V and -160V respectively).
  104   Mon Mar 30 23:30:35 2020 JanAnalysisrun251 - Si-pad performance & status
Attached are plots for Si-pad 2 with hits from ionization of 206Pb81+ at the target.
The plots are representative for all Si-pads, the pattern is always the same!

y-axis: E n-side
x-axis: E p-side strip
condition: E_gate on peak in CsI

While strips 1, 2 and 7 look fine, strips 3 and 6 show already signs of degradation. 
For strips 4 and 5, it is clearly visible that something is wrong.
Those are the central strips, which probably see the most rate.

The same dataset was analyzed here: https://elog.gsi.de/esr/E121/62

This might be a hint to a radiation damage or to the fact that we operate at too low bias voltage (32 Volt).
Maybe it recovers if we increase bias to 60 Volt.

  139   Fri Apr 3 17:55:13 2020 ShahabRunsNice picture from 205-Tl
In this high contrast Schottky recording, the main three frequency peaks are resolved w.r.t. time from left to right:

203 Hg 80 +, 200 Hg 79+ and 205 Tl 81+

There are also some spurs visible, whose nature is not 100% sure. One possible explanation can be:

Since this is taken during the storage time (gas target still off), we have no separation between parent and daughter ions, the daughter 205 Pb 81+ basically has the same revolution frequency as parent. It is a possibility that after the decay, daughter ions are slowly cooled back to the nominal frequency. Daughter ions are highly charged and have a high velocity, so single ion sensitivity is expected. They come from all directions, but Schottky measures only the longitudinal plane. Symmetric spurs can hence be an indication of this.

  167   Mon Apr 6 14:17:54 2020 Yuri, ShahabRunsFRS valves
We saw reduction in ESR beam life. It turned out that FRS has opened valves and venting caused us reduction of the quality of vacuum in ESR leading to beam loss. We manged to closed GEE5VV so that now beam is stable somehow.


how could you guys!!!!

  175   Thu Oct 1 22:20:03 2020 JanDAQfinal unpacker config
We identified an issue with randomly missing adc channels in all lmd-files before run 0273.
This led to errors in the unpacking process. 

This issue is solved with the new config and mapping for the unpacker. 
The respective files are attached here. 
The unpacker is ready to use in /u/litv-exp/unpacker/unpackexps/E121

The adc issue is also understood. We deactivated the internal adc thresholds during the experiment, because we encountered the very same unpacker errors. This solved the problem for all later runs, but we forgot to think about a solution for the earlier runs. 
Mea culpa.

  177   Thu Nov 5 15:13:43 2020 JanAnalysisroot script example
Attached is an example root script/macro that shows how to use scripts for analysis.

Usage:
1. change INPUT and OUTPUT preprocessor variables in e121_analysis.c pointing to your desired input and output root-files.
2. open root and type:
  root [1] .L e121_analysis.C++
  root [2] run()
3. check plots popping up and output files

Hints:
in e121_analysis.C use
#include "e121_raw.h"
for the original channel names/mapping (e.g. ADC1_1,...)
and use
#include "e121_mapped.h"
for named channels (e.g. e_csi[0] or e_dssd_top)
  178   Thu Nov 19 09:14:40 2020 JanDetectorsremote MSCF settings for CsISiPHOS
Attached is a list of all set values for the 5 MSCF shaper modules.
This was done prior to run0251, which served as a final benchmark for those settings.
See: https://elog.gsi.de/esr/E121/62
And https://elog.gsi.de/esr/E121/104

The det. to MSCF assignment is the following:
MSCF 1: Si-pad 1 + 2 p-side/strips (ch. 1-7 + ch. 9-15)
MSCF 2: Si-pad 3 + 4 p-side/strips (ch. 1-7 + ch. 9-15)
MSCF 3: Si-pad 5     p-side/strips (ch. 1-7)
MSCF 4: Si-pad 6     p-side/strips (ch. 1-7)
MSCF 5: DSSD (ch. 1 - 4); CsI (ch. 7 & 8); Si-pad n-sides (ch. 11 - 16)

Note that only the pre-amplification stage of the MSI-8 amplifiers were used for all channels.
  180   Tue Dec 8 15:47:07 2020 JanDetectorsmanual preamp & shaper settings for CsISiPhos
attached is a document showing fotos of all involved amplifiers in the chain to document the manual settings active during the experiment.

Summary:
Si-pad n-sides [MSI-8 (1)] were set to 5 GeV      (expected E-deposition ~2 GeV)
Si-pad p-sides [MPR-32 (1 & 2)] were set to 1 GeV (expected E-deposition ~2 GeV)
DSSD channels  [MSI-8 (2)] were set to 5 GeV      (expected E-deposition ~1.2 GeV)
CsI channels   [MSI-8 (2)] were set to 4 GeV      (expected E-deposition  46 GeV)

It seems we got clipped signals from the Si-pad p-sides, because the MPR-32 were saturated due to a wrong gain setting. 
This might explain, why there was not real influence on the spectra when adjusting MSCF settings for those channels.
 
I cannot comment on the CsI gain setting, because i don't know whether the given GeV-range by MesyTec directly applies for CsI & photodiode.

However, for DSSD and Si-pad n-sides the settings look okay.
