Trying the AIDA format power supply with the simple filters installed.
The detector is attached and HV of 200v@3.8uA
Using one channel from each FEE64 as a guide to compare performance. Using the Integrate analysis function Peak width.
With the bench power supply and the restored setup for the ASICs.
FEE64 #11:1.4.L:311, #12:2.8.L:183, #13:1.4.L:202, #14:1.4.L:342
Change to the filtered power supply
FEE64 #11:1.4.L:345, #12:2.8.L:414, #13:1.4.L:311, #14:1.4.L:476
Add Braid between the LEMO00 connectors on the two adaptor boards using "croc" clips.
FEE64 #11:1.4.L:172, #12:2.8.L:141, #13:1.4.L:106, #14:1.4.L:161
Change the shaping time of all the ASICs from 0.5uS to 5uS
FEE64 #11:1.4.L:128, #12:2.8.L:127, #13:1.4.L:119, #14:1.4.L:199
I think this means the AIDA power supply with the simple filters is equivalent or better than the bench supply.
Good news I think.....
It needs a more extensive test ( more channels ? ) |
