Entry  Wed Jun 26 16:20:31 2019, Jan, DAQ, unpacker: lmd > root E121.specdet_mapping.hh
I have written an unpacker for the lmd data taken with the current daq-system for E121.
The crate configuration is as follows:
ADC1 channels 1-32 (Caen 785)
ADC2 channels 1-32 (Caen 785)
ADC3 channels 1-32 (Caen 785)
SCALER channels 1-32 (Caen 830)

The unpacker binary can be found here
/u/litv-exp/unpacker/unpackexps/E121/E121

The current spec file is attached.

To convert lmd-files to root-files, please use it as follows:

Entry  Mon Mar 30 16:25:05 2020, ruijiu, Detectors, turn down the HV 
turn down the hv and pull out the detector.  

suggest by 
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

Entry  Mon Mar 30 15:03:58 2020, ruijiu Tino, Yuri, Lasoro, Nik and Uli, Detectors, the gas bottle is empty. IMG_20200330_152735_mh1585575780057.jpg
The gas bottle was empty. Tino replaced 
the previous old bottle with 50 bar gas left. 

Yuri is getting new gas bottles.

Yuri got a new gas bottle. We repalced 
the the new gas bottle. There is 200 
bar gas left now. 
The old gas bottle with 50 bar gas 
left was kept inside ESR.
The empty gas bottle was removed from 
ESR.  

The outlet volve was decreased by 30 degree.
Since the value is almost 0, we can not read the value of outlet volve.

store 206Pb81+ beam inside ESR and measure its halflife. 
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.

Entry  Wed Dec 5 17:29:24 2018, Chen, Sidhu, Detectors, signal map 13x
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:











Entry  Thu Apr 2 12:52:25 2020, ruijiu, General, setup FRS with 2 g/cm2 degrader. 
Yuri sets up FRS with 2 g/cm2 degrader (previous one is 1 g/cm2). The ESR is not changed. The contamination should be less now.
Entry  Mon Mar 30 23:30:35 2020, Jan, Analysis, run251 - Si-pad performance & status 7x
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.
Entry  Sun Mar 29 23:48:12 2020, Jan, Analysis, run0251: E_spectra for CsISiPhos  14x
This is a collection of energy spectra of the CsISiPhos detectors from run0251 with primary beam.

There is no good spectra for n-side of Si-pad 1!
Entry  Sun Mar 29 13:04:32 2020, Ragan, RuiJiu, Runs, run file: 1298 61308F61-2C4C-4651-8C74-608E4E585B14.jpegEB5CA42A-B8DC-4892-8357-9006A1C3BAC0.jpeg
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 :) :) 
Entry  Thu Nov 5 15:13:43 2020, Jan, Analysis, root script example e121_analysis.Ce121_mapped.he121_raw.h
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)

Entry  Thu Nov 19 09:14:40 2020, Jan, Detectors, remote MSCF settings for CsISiPHOS setting.1585477986det_mapping.png
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.
Entry  Sat Mar 28 16:09:50 2020, Alex, General, no 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.
After this, there is no beam in the ESR.
