12.40 The snout w/bPlast plus 3xDSSSDs was removed yesterday AIDA pulser tests via adaptor PCB test inputs, i.e. zero capacitative load and zero leakage current per FEE64 1.8.W spectra - attachments 1-4 per FEE64 Rate spectra - attachment 5 per FEE64 1.8.L spectra - attachments 6-7 From the per FEE64 1.8.L FEE64 FWHM 1 - 2 45 3 25 4 - 5 - 6 45 7 25 8 37 9 30 10 38 11 19 12 35 For comparison we would expect to obtain ~ 15-20 ch FWHM (~10.5-14 keV FWHM) based on tests conducted at T9, STFC DL. The peak widths observed above are significantly worse than expected. Are the adaptor PCBs currently grounded to FEE64 Cu mezzanine cover?
