Follows the A, B and C procedures to take a RICH pedestal run, generate the pedestal files and make them visible to the DAQ.
Contents
A) Take the RICH pedestal run
a1. Ask MCC for beam OFF
a2. login as a-onl@adaql4 (l5, l6 or l7)
a3. go to the directory: /adaqfs/home/a-onl/rich/pedestal
a4. do the command: ./preped.sh
a5. prescale all trigger except T3 and T5
a6. run a standard calibration run in TwoArmRICH (comment as RICH pedestal), deadtime should be araound 15% at 25 Hz
a7. take 2000 events at least, then stop the run
B) Generate the pedestal files
b1. login as adaq@adaql6 (or l7)
b2. go to the directory: /adaqfs/home/adaq/e06010/rich/leftreplay
b3. run analyzer
b4. within analyzer do: .L newdecodeRICH.C+ (note: to speed up the processing, do not forget the + at the end)
b5. then run: newdecodeRICH(####) where #### = number of the pedestal run
b7. check the message about pedestal and noise means at the end of the processing
b6. quit analyzer: .q
C) Make them visible to the DAQ
c1. go back to a-onl@adaql4 (or higher) in the directory /adaqfs/home/a-onl/rich/pedestal
c2. run the script: ./copyped.sh (check the messages about file length)
c3. you can now start the production; do not forget to set the prescalers correctly
Additional Information
The file save/log.txt keeps track of the operations of the above scripts preped.sh and copyped.sh and therefore of the pedestals used in the data acquisition in each run.
Moreover copyped.sh backups a copy of the latest pedestal files in a subdirectory in save/; the subdirectory is written in save/log.txt.
