Date: 02 December, 2010 File: start_coda.html
- FADC CODA is running on 'hamoller' computer under 'moller' account.
To start CODA one can type command: 'start_coda_brad' - that fires up the usual set of windows for ET, ER, EB, etc. For FADC DAQ 'fadc_moller' configuration is used.
- FADC parameters.
There is configuration file with settable parameters for FADC. File is located in directory: ~moller/crl/FADC/fadc_params.cnf Parameters from file are loaded to FADC in 'Prestart' state of CODA. There is self explained list of FADC parameters from configuration file:
# Wed Apr 21 16:22:20 EDT 2010 # FADC settable parameters
# Threshold on calorimeter sums (define triggers and SW scaler logic) FA_SUM_THRESH_CR 8500 FA_SUM_THRESH_CL 8500
# Threshold on individual channels # Define SW scaler logic for Scintillators only # Controls digitized data output for all channels (ie. 'zero-suppression') FA_CHN_THRESH_SR 500 FA_CHN_THRESH_SL 500 FA_CHN_THRESH_CR 500 FA_CHN_THRESH_CL 500
## Prescale range: 1--2047 FADC_PRESCALE_CL 1000 FADC_PRESCALE_CR 1000 FADC_PRESCALE_CRL 200 ## These many DATA trigger are grouped into each DATA interrupt FADC_EVENTS_PER_BLOCK 20
## PULSE_WIDTH range is from 3--255 (3 is default) FADC_PULSE_WIDTH 3
## COIN_WIDTH range is from 1--255 (2 is default) FADC_COIN_WINDOW 2
## Delays range: 1--255 FADC_DELAY_CL 0 FADC_DELAY_CR 0 FADC_DELAY_SL_0 1 FADC_DELAY_SL_1 1 FADC_DELAY_SL_2 1 FADC_DELAY_SL_3 1 FADC_DELAY_SR_0 1 FADC_DELAY_SR_1 1 FADC_DELAY_SR_2 1 FADC_DELAY_SR_3 1 ## This delay is for the _delay counts (random background measure) FADC_DELAY_SRL 25
