Implantation stack mounted - BB18(DS)-1000 + bPlas + bPlas + 3x BB7(DS)-1000 N.B. aida02, aida09 & aida15 have grounded copper screen (3M 1245 - aluminimum braid to copper screen of ribbon cables) for Kapton PCBs connecting the Samtec ribbon cables to the BB18 DSSSD. n+n FEE64s aida02, aida04, aida06 and aida08 LK1 fitted p+n FEE64s aida03 and aida07 LK3 fitted BB7 aida10 (asics #1-2 p+n, #3-4 n+n) BB18 p+n FEE64s 9-15, 1-3, 5-12 - n+n FEE64s 2-4 (L-R looking downstream) 10.30 FEE64 power ON DSSSD bias ON (BB18 only) - attachment 1 leakage current OK ASIC settings 2024Dec13-17.02.45 restored p+n FEE64 slow comparator 0xa, n+n FEE64 slow comparator 0xf Attachments 2-7 WR timestamp aida05 & aida12, system wide check aida12 & aida05 global clock status 6 - to be checked - OK for initial tests without merger WR decoder status aida02 per FEE64 Rate spectra - attachment 8 aida10 high rate - BB7 not biased rates OK for p+n FEE64s, rates high for n+n FEE64s - to be checked BNC PB-5 pulser ON to p+n FEE64s - no obvious adaptor PCB misalignments ADC data item stats - attachment 9 rates generally OK aida10 high - BB7 not biased aida02 & aida04 n+n FEE64s - rates high - to be checked when bPlas install complete all p+n FEE64s connected to BB18 <10K except aida05 25k - very good! BNC PB-5 settings - attachment 10 WR timestamps OK - attachment 11 FEE64 temperatures OK - attachment 12 12.15 bPlas driver PCB installed, bPlas cabling and grounds *not* connected yet ADC data item stats - attachment 13 all rates higher cf. attachment 9 per FEE64 Rate spectra - attachment 14 per p+n FEE64 1.8.L spectra - attachment 15 aida09 pulser peak width 69 ch FWHM = 49keV FWHM aida14 pulser peak width 50 ch FWHM = 35keV FWHM per p+n FEE64 1.8.W spectra - 20us FSR - attachments 16-17 per n+n FEE64 1.8W spectra - 20us FSR - attachment 18 DSSSD bias & leakage current OK - attachment 19 ambient temperature +21.6 deg C, d.p. +0.4 deg C, RH 24.4% FEE64 temperatures OK - attachment 20 DSSSD bias volatge & leakage current OK - attachment 21 CAEN N1419ET ch#0 BB18, ch#1 BB7 Install of bPlas drivers, cabling, grounds complete ADC data item stats - attachment 22 per FEE64 Rate spectra - attachment 23 all BB18 p+n FEE64s *except* aida05 show very low rates of noise per p+n FEE64 1.8.L spectra - attachment 24 aida09 pulser peak width 62 ch FWHM = 42keV FWHM BB18 p+n FEE64s better electronic noise cf. p+n FEE64s not connected to a DSSSD per FEE64 1.8.W spectra - 20us FSR - attachments 25-26
