Backup Data Files to SILO

Cron scripts are installed on the idaq account on opsmdaq0 to back up data and delete it from /data and /data1: 

/opt/idaq/cron/cron_opsmdaq0

Do not attempted to copy, delete, move, or rename files. Never !

The scripts assume that data appears in /data*/DIR where DIR = "annihilation" or "compton" or "mott" Files must have the keywords "PEPPo" or "Scalers" or at least "dat". This avoids writing scratch files like root output. Do not start putting data in some new place or with new names. It won't be backed up to MSS if you do that.

The data are deleted from local disks if they have been written in duplicate with correct byte count to the MSS tape silo. The data stay on disk for an amount of time that is related to the amount of disk space is available. If lots of disk available, the data stay forever. If not much disk, the data are deleted aggressively. 

 The data is copied to: /mss/accel/peppo/raw

The copying of data was disabled on January 3rd, 2014.

  • Reference: JLab Module Manuals [1]
  • Changed Mott_SemiInt to the FADC Mode 7 from Mode 3 -- Done on April 29, 2014. This mode provides:
  1. Pulse integral (sum of all 4ns samples over set threshold, up to 3 pulses per window)
  2. Pulse time (62.5 ps resolution)
  3. Pedestal average of 4 samples at beginning of window.
FADC Programmed Thresholds:
  1. Mott_Sample: Threshold = 0
  2. Mott_SemiInt:
 CH1 - E LEFT            Threshold = 600
 CH2 - E RIGHT           Threshold = 600
 CH3 - E UP              Threshold = 600
 CH4 - E DOWN            Threshold = 600
 CH5 - dE LEFT           Threshold = 600
 CH6 - dE RIGHT          Threshold = 600
 CH7 - dE UP             Threshold = 600
 CH8 - dE DOWN           Threshold = 600

Trigger Prescale

The input trigger can be prescaled by the ti:prescale parameter in the Configuration File 

 /*
    Trigger Prescale := 1 / 2^(prescale)
    prescale is fixed to 0 for Mott_Int
 */
 prescale = 0;

jeviodmp

The Java-based event display utility can be used to navigate through the data files.

evio2xml

The event format utility (evio2xml) can display, in a readable XML format, events from the data files. 

evio2xml [-max max_event] [-pause] [-skip skip_event]
         [-dict dictfilename] [-dtag dtag]
         [-ev evtag] [-noev evtag] [-frag frag] [-nofrag frag] [-max_depth max_depth]

Issues and FAQ

  • RunNumber: if the run number in msql is different from the one in CODA cool database, coda doesn't work. Open dbedit => localhost => sessions and change the RunNumber to match the one in CODA cool database.
