Ragan | General | 203Tl80+ 200Hg79+ 205Tl81+ |
Below in the schottky spectrum, on left is 203Tl80+ contamination, in middel is 200Hg79+ contamination and on right most is 205Tl81+.
These contaminations cannot be seen on CsISiPHOS but can only be seen on schottky.
The goal now is to get rid of these contaminations by putting slits. |

Ragan | General | 200Hg79+ 205Tl81+ |
203Tl80+ impurity is removed by moving scrapper inside ESR.
Only 220Hg79+ is left now |

Ragan | General | Separation of 203Tl80+ and 200Hg79+ using scrapper in ESR |
It can be seen in the video how 203Tl80+ (on extreme left) and then 200Hg79+ (in middle originally) is separted from 205Tl81+ by using scrapper in ESR.
Now, we want 205Pb81+ mixed with 205Tl81+ to be separated as much as possible in FRS. |

Ragan | General | Stochastic cooling and orbit problem |
On 1 April by 5 pm, we could stop the stochastic cooling after the stacking process and also change the orbit of the Tl beam to centre.
Thanks to the efforts by the ESR team ! |

Mei,Yury, Tino, Ragan, Ruijiu | General | Shift 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 |

Jan Glorius | SlowControl | EPICS ioc on raspberry |
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 |

Jan Glorius | SlowControl | GUI 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 |

Jan | DAQ | MBS 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
forks './rawServRFIO64-wheezy' for each client request - inside screen go to 1st tab and connect MBS to RFIO server
<Ctrl-a 0>
mbs > @connect
mbs> show file
mbs> -R4L-47 :transport :Name of output device = RFIO
-R4L-47 :transport :current tape label = lxg0155 , opened

Jan | DAQ | unpacker: lmd > root |
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:litv-exp@lxg___: E121_unpacker /path/to/file.lmd --ntuple=RAW,/path/to/new_file.root |
