test_1881 #slot
August 04
1st version of readout list is successfully loaded.
Modules should work in Multi-Block Mode, so there should be more than 2 ADC boards in the crate.
A simple replay code is developed and available at cpeng@ifarm
August 05
Readout list from Brad (hsft01.crl) is modified and tested. It can take data from up to 3 1881M ADC boards.
Some limit and problems are:
- More than 4 ADC boards result in an "exception of interrupt" and reboot of the single board computer.
- Need to update the crate map in the readout list (how many boards and at which slots they are)
Replay code is refined, it can automatically divide the data for each channel on each ADC board, right now it can only decode for a crate with up to 3 ADC cards.
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
Readout list (pradtest.crl) is upgraded, it solves several problems, including:
- Now it supports
The limit is:
- It can only be used for ADC 1881M boards, no TDC is supported
- There should be more than 2 ADC boards in the crate to work on the Multi-block Mode.

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 Run 110)
18 and 20 are left to be tested again in the next run
Run Number: 112
Slots: 6, 7, 8, 9, 10, 11, 12, 13, 14, 15
ADC Number: 18, 20, 24, 25, 26, 27, 28, 29, 30, 31 (additional board, numbered as 31, no mark on the board)
Board 18, channel 32 has no readout, it fails 3 tests (run 110, 111, and 112) in a row.
Board 20, channel 32 has readout now, but all of its channels have a wide spread of pedestal. width is about 20 ~ 25, has a slope at the left.
