August 05
1st version of readout list. Can take data from up to 3 1881M ADC boards.
Run Number: 91
ADC Number: 26, Slot 4. ADC Number: 7, Slot 5. ADC Number: 28, Slot 6.
Run Number: 98
ADC Number: , Slot 9. ADC Number: , Slot 10. ADC Number: , Slot 11.
August 06
Slot 13 in the test crate (the most left) is found problematic ADC #30 is found problematic
New readout list is compiled and tested. It solves several problems.
August 07
Test for all boards
Run Number: 106
Slots: 6, 7, 8, 9, 10, 11
ADC Number: 1, 2, 3, 4, 5, 6
All boards passed the test
Run Number: 107
Slots: 6, 7, 8, 9, 10, 11
ADC Number: 7, 8, 9, 10, 11, 12
All boards passed the test
board 8 was marked as "wide pedestal". No difference seen.
board 7: channel 58, no readout.
board 10: channels 16 ~ 31, 48 ~ 63, no readout
board 11: There are uniform background with a width of 80 for each channel
Double check, run number: 108
Change slots and use the problematic boards only
Slots: 14, 15, 16
ADC Number: 11, 7, 10
Every problem disappears
Run Number: 110
Slots: 6, 7, 8, 9, 10, 11, 12, 13, 14, 15
ADC Number: 13, 14, 15, 16, 17, 18, 19, 20, 22, 23
Number 21 is TDC 1877, will not be used in this experiment
All boards passed the test
Some events are bad on boards at slot 9, 11, 13. The installation is not very tight, it might be the reason.
Re-insert the boards Run Number: 111
Bad events are gone, but the channel 32 on both of board 18 and 20 has no readout. (The same as they are in Run110)
18 and 20 are left to be tested again in the next run
Run Number: 112
