Fri Dec 7 10:56:04 2018, 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:

We have a GUI for remote controlling our MesyTec modules MSCF16 and MHV4 for E121 experiment.
Here is the instructions to run it:

We have a GUI for remote controlling our MesyTec modules MSCF16 and MHV4 for E121 experiment.
Here is the instructions to run it:
|
|
Tue May 28 08:36:14 2019, 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)
|
|
Wed Jun 26 16:20:31 2019, 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)

Tue Aug 27 14:53:47 2019, Chen, Sidhu, Detectors, The thickness uncertainty of Ta is less than 1%.
|
The thickness of Ta plate have been measured by target group. The result is show as following.
According to this measurement, the thickness uncertainty is less than 1%.
This thickness uncertainty is good enough for Tl experiment.

Be careful. The voltage value on user interface is 10 times of real value. e.g. if the real value is 32V, the voltage value on UI has to be 320V.

Thu Mar 26 17:21:40 2020, Ragan, General, Stochastic cooling
|
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. |
