Shift Summary

Beam, target density and vacuum appear to have been stable overnight

FEE64 temperatures continue to cycle

Evidence of some radiation damage DSSSDD 0 presumably for most forward lab angle strips?

aida12 asic #1 and #2 high rate HEC activity - fixed by ASIC check load

DSSSD 0 aida01 1*L spectra, aida04 **L spectra

Double peak structure feature of aida04 ( n+n Ohmic side ) strips. Single ( albeit sometimes broad peak ) observed in aida01 ( p+n junction side ) strips.
Not currently observed by DSSSD 1-3. DSSSD 0 high energy peak rate far higher than DSSSD 1-3.

Data from last week did not display this double peak but DSSSDs and beam have been moved since.

Unclear whether this reflects radiation damage and/or wafer/active area edge effects on the n+n side.
Might also reflect beam characteristics throughout cycle.

Requires calibration and dE cut to investigate.

JM comment -> early time cut analysis indicates this is a beam effect. DSSD#0 has majority of halo on it so double peak is very pronounced. 
We observe double peak all DSSDs just to a much lower level.

Summary

All FEE64s appear to be working (except aida05 which has c. 8 missing channels) with pulser - which 
validates the FEE64, ASICs and adaptor PCB.

Electronic noise c. 50keV FWHM for aida01 & aida03 - other FEE64s better/worse.

Preamplifier noise appears to be similar for all FEE64s which may suggest an issue with the test signal chain

1) STOP DAQ [workspace 2, 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'

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

3) Setup Merger by selecting 'SETUP' [workspace 3, display 1, browser tab 'NewMerger Control']

4) Start Merger by selecting 'GO' [workspace 3, display 1, browser tab 'NewMerger Control']
     all data links will be inactive (red)

5)   Disable data transfer by selecting 'Data transfer Disable #1 all' [workspace 2, display 1, browser tab 'Run Control']

6) Start DAQ

    Start DAQ by selecting 'GO' [workspace 2, display 1, browser tab 'Run Control']
     check that DAQ is *actually* going - if not repeat 'GO'

7) Check WR timestamps by selecting 'Collect all timestamps' [workspace 2, display 1, browser tab 'GSI White Rabbit Control']
     readout times will be displayed for each FEE64
     check that the readout times are monotonically increasing as you read down the list of readout times - if not, contact expert support

8) Stop DAQ 

    Start DAQ by selecting 'STOP' [workspace 2, display 1, browser tab 'Run Control']
     check that DAQ has *actually* stopped - if not repeat 'STOP

9) Enable data transfer to Merger and TapeServer and start DAQ

    Enable data transfer by selecting 'Enable data transfer Enable #1 All' [workspace 2, display 1, browser tab 'Run Control']

    Start DAQ by selecting 'GO' [workspace 2, display 1, browser tab 'Run Control']
     check that DAQ is *actually* going - if not repeat 'GO'

10) Check data is being transferred to Merger and TapeServer

    Select 'Reload' [workspace 3, 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 3, display 1, browser tab 'TapeServer']
     you should see 'Blocks written' and 'kb written' counters increase

11) Check AIDA data is being forwarded from the TapeServer to MBS [workspace 3, display 2, command terminal]

12) Restart should now have been successfully completed. Please inform the 'on shift' crew' that AIDA is forwarding data.

    If not, please request expert assistance.
