Start CODA
 
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
 
 
 
Data stored on 'hamoller' computer to directory: /data1/raw/
