Observed reduction in YR09 presure over last few hours in ML online plot. Beam intensity looks OK but target density was fluctuating quite a lot. Current value was 1.5e11.

Changed the nozzle position slightly which increased target density to 5.5e11. Pressure in YR09 looks OK.

I accidently scrolled slightly with the target code (only by 100 but am not sure). Target looks stable but I will not touch remotely again for fear of losing total target position.

Rates in ADC data items statistics and in the monitoring code look consistent with beam on target.

Run stopped to change beam energy

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.

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.
