*2:30 pm*: changed power source of USB-controlled power supply for FEEs. Now one of the power cables is connected
to the 'B' power supply of F11, and the second to the 'C' power supply (these are in the unit on top of WASBI
crates). The reason for change is that before both were connected to 'C', and drained current was very close to
limit of 10 A (and power cord getting noticeable hot). We'll check resolution after this switch.
Detectors 1, 2, 3, and 4 biased to 100V, detectors 5, 6, and veto biased to 70V.
n-side is more noisy than p-side, but resolution comparable to previous configuration:

*5 pm*: Set-up correlation scalers for AIDA<->EURICA<->BigRIPS (detail diagram coming soon, now only in paper
logbook).
*6:30 pm*: Started EURICA DAQ with Pieter and Gabor.
A folder is created to record data of June campaign: /raid/11/mbs/2016_ucampaign/
Tested correlation of AIDA and EURICA with a pulser run, triggering EURICA and AIDA correlation scaler with 250
Hz. The corresponding files are
/raid/11/mbs/2016_ucampaign/test0003.lmd
/TapeData/may2016/R12_0.gz
Phong did a quick analysis and the pattern of correlation scalers in both files is similar (attached figures). It
is also consistent with the number of reset requests we sent during the data taking (three requests closely spaced
in the middle of run, and two more in the end of the run). |
