Michael is modifying the settings of the electron cooler --> changed beam from bunched to coasting

Merger, Tape server (WS3) checks: DONE, writing ~1036 kB/s, refreshing is fine

Leakage current (WS4): 3.46 uA , stable current

DAQ (WS2): temperature checked,

     - clock status:

Clock status test result: Passed 5, Failed 0

Understand status as follows
Status bit 3 : firmware PLL that creates clocks from external clock not locked
Status bit 2 : always logic '1'
Status bit 1 : LMK3200(2) PLL and clock distribution chip not locked to external clock
Status bit 0 : LMK3200(1) PLL and clock distribution chip not locked to external clock
If all these bits are not set then the operation of the firmware is unreliable

  221   Mon Feb 21 20:56:51 2022 SHB, JM, CB, OH (remotely)DAQ connection for ion current

signals from ICT and CRYRADIO are now connected to AIDA2 and AIDA5 respectively. ICT is set to factor 200 and CRYRADIO to 40 for now.

  220   Mon Feb 21 18:03:58 2022 SHB, JM, CB, OH (remotely)Info: signals on ion intensity for experiment

Currently 4 possibilities to have a look at the beam, all of them are OK to check whether there is beam or not, but some of them are better for checking absolute values.
- Schottky RF signal
- Schottky zero span signal
- CRYRING Radio (signal from BPM) --> YR12DA1R
- ICT (integrated current transformer) --> YR12DT1C


absolute measurements:

- currently the beam is at 5.5 MeV/u calibrated on the flat top. The signal of ICT before is noisy but on the flat top it is well calibrated.


relative measurements:

- The signal from CRYRING radio, has a good amplifier and is frequency independent with a nice log signal. it can be used for relative measurements

- The zero span signal of Schottky can be used, but it is not reliable for measuring the number of ions since change in the control room may change the signal level.

- Schottky RF signal can be viewed by running Launcher-App using the button "VNC Tektronix RSA". The only problem is that only one instance can run, so if in the control room someone needs it, in the container it will disappear.
