FEE64 configuration https://elog.ph.ed.ac.uk/AIDA/935

Note

- aida06 not connected to DSSSD ( cabling broken  - will be replaced later this week )

- LEC ( 20MeV FSR ) data ADC offset corrected 
   ADC offsets available for 489 of 512 channels and are included in the analysis - 23 strips for which no ADC offsets could be calculated ( usually because there was 
no 
pulser data ) are not included in analysis 
- LEC ( 20MeV FSR ) front-back strip energy difference cut +/- 50 channels ( c. +/- 280keV )
- HEC ( 2GeV FSR ) front-back strip energy difference cut +/-200 channels ( c. +/- 1120MeV )

- LEC ADC data: 13 < channel < 188 ( c. 73-1053keV )
- HEC ADC data: > 13 channels ( c. 73MeV )
- FEE64 hardware thresholds: LEC c. 100keV, HEC c. 200MeV

Attachments 1 & 2 - per pixel HEC-LEC event time difference spectra - 4.096us/channel

Attachments 3 & 4 - per pixel HEC-LEC event time difference spectra - 65.536us/channel

Attachment 5 - DSSSD x-y hit pattern: HEC-LEC event time difference < 4.3s
 Majority of events associated with 'hot' p+n junction strips - few plausible decay candidate events - as expected.
 z-scale - semi-logarithmic - scattered events are single counts ( blue )
 1 count => rate ~ 1/2355s ~ 0.0004Hz, the great majority of pixels have zero counts

Attachment 6 - LEC ( decay ) and HEC ( implant ) events - 262.144us/channel ( 65536 channels = 17.2s )

HEC implants channels 12000-25000 = 216 counts => HEC rate ( in spill ) 63.4Hz
LEC decays channels 12000-25000 = 3865 counts => LEC rate ( in spill ) 1134.1Hz
LEC decays channels 25000-38000 = 2790 counts => LEC rate ( inter spill ) 818.7Hz

Attachment 7 - per pixel HEC-HEC event time difference spectra - 4.096us/channel

Attachment 8 - per pixel LEC-LEC event time difference spectra - 4.096us/channel

Attachment 9 - variables.dat
This is a ( Fortran ) Namelist I/O data file containing of the ADC offsets, FEE64 configuration, LEC and HEC energy difference windows

The ADC offset channel number is calculated as

channel = channel_ident + ( module * 64 ) where module = 0-7 corresponding to AIDA FEE64s aida01-aida08

and is used as follows

ADC data = INT ( RSHIFT( ABS( 32768 - data( i ) ), 3 ) - offset( i ) + 0.5 )

where data(i) is the ADC data item for channel i, offset(i) is the ADC offset for channel i

An ADC offset of -9999 means there was no pulser data for this channel in data files R5 and R11.
