Offline data analysis of data file R52 
c. 1h 2.25MeV neutrons from 10uA p+ + 410ug/cm2 LiF -> copper block -> sample #4 Mylar+NaCl+197Au

ADC data are offset corrected but not gain matched.

Attachments 1-2 - DSSSD#1 and DSSSD#2 ADC spectra (10keV/channel nominal)

Attachment 3 - ADC hit pattern (DSSSD#1 0-15 p+n/16-31 n+n, DSSSD#2 32-47 p+n/48-63 n+n)

Attachment 4 - energy (10keV/channel nominal) versus channel (DSSSD#1 0-15 p+n/16-31 n+n, DSSSD#2 32-47 p+n/48-63 n+n)

Attachment 5 - per DSSSD p+n junction energy - n+n Ohmic energy + 2048 (10keV/channel nominal) - with/without energy difference gates currently set to 1948-2148 (i.e. 
non-
selective)

Attachment 6 - per DSSSD p+n junction energy versus n+n Ohmic energy (20keV/channel nominal) - with/without energy difference gates currently set to 1948-2148 (i.e. 
non-selective)

Attachment 7 - scaler spectra (1000x rate updated every 60s)

Attachment 8 - sort program variables

Issues

From pulser tests and pulser walkthrough (R51) all channels are OK *except* channels 14, 40, 41 with no data

From data with beam (R52)

Channels 24-31 - little data - check RAL109 LLD?

Channel 23 - no ADC data => issue between preamp and Si wafer or RAL109 discriminator

Channel 36 - low amplitude ADC data => issue between preamp and Si wafer

Channel 58 - no ADC data => issue between preamp and Si wafer or RAL109 discriminator
