Sat Dec 12 03:30:50 2015, Alfred, Chris, Phong, change configuration of NNAIDA modules in setup
|
We want to reduce the configuration of the setup to 4 FEE cards (8 NNAIDA modules), so we only have to isolate 4 of them from the cooling crate for a
noise test. Following instructions in April2015 test logbook.

*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

Continued work on beta-trigger for EURICA. However the system seems to have different noise condition than before, which
we think appeared after we changed power source for FEE's PSU (https://elog.ph.ed.ac.uk/AIDA/220). This is high frequency
noise of low amplitude, with a period of 10 usec.

The main experiment changed to a carbon reaction target at F8 (similar thickness of CH2 previously used), and retuned the ZDS. First BigRIPS run after
retuning is 40Mg_1093 (at 2:29 am, Nov 30th)
The background at F11 has increased. The neutron backgroun incresead by a factor of ~10. The rates of visual scalers also increased; for example |

We noticed a peculiar feature in the time-stamp synchronization monitor. The spectra of timestamp difference between pairs of DAQ systems show, for all
possible pair combinations, a peak at Delta(ts)= 65535 = 2**15
This corresponds to a difference of 2.6 ms (for 25MHz correlation clock). See the attachments taken ~23:00 of Nov 28th. |
