Offline analysis of
AIDA RIBF128/R5_124 to R5_148 data "130Ag setting", June 2017 RIBF128 experiment *yellow*
AIDA Oct17/R17_31 to R17_34 data "84Ge setting" , October 2017, 78Ni experiment *red*
AIDA Nov17/R2_8 to R2_16 data "115Nb setting", November 2017 RIBF139 experiment *blue*
N.B.
1) no software thresholds
2) no PID correlation
3) unless otherwise stated, all implant energies are the stopping layer implant energies
Attachment 1 - *total* implant energy for AIDA DSSSD stack (5.6MeV/channel)
Attachment 2 - implant energy for stopping DSSSD layer (20MeV/channel)
Attachments 3-4 - per pixel implant-decay correlation times (163.84us/ch)
The 130Ag data (yellow) clearly shows the "20ms bump" but the later test data (red & blue)
with the revised AIDA FEE64 adaptor PCBs *and* using ASIC setting I_bias LF feedback 0x8 -> 0xf
for all p+n FEE64s shows (with the limited statistics available) no evidence of a "20ms bump". |
