 Tue May 7 15:52:47 2019, Chen, Sidhu, SlowControl, GUI for remote control of MSCF+MHV4 [detailed] 
|
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
litv-exp@astrum1:~$ ssh -X litv-exp@lxg1254.gsi.de
2. get the EPICS environment by typing in terminal: epicsfind
litv-exp@lxg1254:~$ epicsfind
Found nice EPICS in /u/litv-exp/epics/opt_x86_64-linux-gnu_4.9.2.
3. type in terminal: GUIe121 (alias for 'medm -x /u/litv-exp/E121/medm/e121.adl')
litv-exp@lxg1254:~$ GUIe121
if you get the message: 'medm: command not found' you didn't load the EPICS environment (1.)
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 |

Mon Apr 6 14:17:54 2020, Yuri, Shahab, Runs, FRS 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!!!!
arrrrgggggggg!!!!!!! |

Fri Mar 27 13:04:17 2020, Ragan, General, FRS 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. |
