1) Select 'No Storage' [workspace 4, display 1, browser tab 'TapeServer']
    If already in 'No Storage' mode please ignore this step

2) STOP DAQ [workspace 3, display 1, browser tab 'Run Control']
   all FEE64s should change status from 'going' to 'stopped' *except* whichever FEE64(s) have a problem - typically their status is 'going' or 'error'

3) Restart Merger by selecting the Merger icon [workspace 4, display 2]
    terminal window showing the startup will popup

4) Setup Merger by selecting 'SETUP' [workspace 4, display 1, browser tab 'NewMerger Control']

5) Start Merger by selecting 'GO' [workspace 4, display 1, browser tab 'NewMerger Control']
     all data links will be inactive (red)

6) Start DAQ by selecting 'GO' [workspace 3, display 1, browser tab 'Run Control']
     check that DAQ is *actually* going - if not repeat 'GO'

7) Check data is being transferred to Merger and TapeServer

    Select 'Reload' [workspace 4, display 1, browser tab 'NewMerger Control']
     you should see a non-zero 'current merged data rate' and all links should show as green at least some of the time (requires observation over several reloads)

    Select 'Reload' [workspace 4, display 1, browser tab 'TapeServer']
     you should see 'Blocks written' and 'kb written' counters increase

8) Unselect 'No Storage' [workspace 3, display 1, browser tab 'TapeServer']
    If already in 'No Storage' mode at the start of this procedure please ignore this step


   If you continue to have problems, please request expert assistance.

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.
