Beam continues to turn off and on

CG, AE, TD, DK | Wednesday 30 November | 00.11 Beam stopped for target @F8 change.
R35 stopped at R35_62.
BRIKEN file 161129_1951 155->159
BigRIPS files 1084-1088.
Bias and leakage currents ok (attachments 1+2).
00:38 Added 0.2 mm Al fixed degrader. The new target at F8 is 0.9 g/cm2 C, which (according to LISE calculation)
results in 2.7 MeV/u less energy loss than the previous 0.9 g/cm2 CH2 target.
00:42 Beam returned. R36 started. BigRIPS file 1089.
Initially out of sync with BRIKEN so reset correlation timestamp @ 01:45 (~1/2 way through R36_0).
02:26 Beam rate at F11 about doubled. Now ~80cps @ F11.
Previously changing beam spot position, but now 41Al now centred.
02:39 Beam stopped start @ of R36_11.
03.33 Beam returned to F11, centred on 40Mg in ZDS.
Just after start of R36_22.
BigRIPS file 1094.
04.35 Beam stopped. ~1/2 way through R36_34.
Continue running with R36.
06.13 R36 stopped.
The control module of a power supply of one of the STQs has broken and the accelerator team must contact the
manufacturer to work out a solution.
This will take some time (hours or maybe even into tomorrow).
09.36 STQ PSU fixed - beam returns
BigRIPS data file 1096
10.00 AIDA DAQ soft reset to recover from LN2 fill cycle transient

10.50 Unable to sync DAQs - appears BRIKEN timestamp is not being reset, AIDA-RIBFDAQ appear to be sync'd
11.16 Looks like BRIKEN gets the sync again. It's some kind of integer overflow issue?! Unclear.
BRIKEN starts the new run. It is the same time as AIDA R38_14 (about 400 MB into file)
11.43 BigRIPS data file 1098
12.47 BigRIPS data file 1099
13.02 DSSSD bias & leakage currents OK - see attachments 3 & 4

All FEE64s << 100 k data items/s

13.20 DAQ stopped OK (RIBF0R1/R38_35)
Change degrader to (8mm Al) fixed + ( 0.5mm W/1mm Al + 1mm W/1m Al) variable, i.e. additional 0.2mm W

B-rho changed from 6.384Tm to 6.673Tm overnight => 9.3% energy change
A=40 ions at F11 change from 145MeV/u to 158MeV/u
14.22 Beam was off to change stripper foil. Now it is back at F11, around 10 cps at the scint (BigRIPS scaler) or
60 cps at our normal F11 plastic
Very nearly the time of R39_12 beginning.
BigRIPS run 1101
15.25 Offline analysis indicates we need to increase degrader thickness further
Will add 0.5mm W/1mm Al to change degrader to (8mm Al) fixed + ( 0.3mm W/1mm Al + 0.5mm /1mm Al + 1mm W/1mm Al
) variable
15.30 DAQ continues (RIBF03R1/R39_25)
BRIKEN data file 178
16.06 BigRIPS data file 1103
16.23 We observed that the degrader was not actually inserted previously as we thought.
Now it is inserted, so variable degraders 1, 2 and 3: 0.5 mm W (+1 mm Al), 0.3 mm W (+1 mm Al) and 1.0 mm W (+1
mm Al)
AIDA run is R39_36
