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. - To list: crontab -l - To remove: crontab -r - Check again: crontab -l - To load: crontab cron_opsmdaq0 (in /opt/idaq/cron)

- Summary of FADC250 Operating Modes (2/18/14): Media:FADC250_modes_2.pdf
- Changed Mott_SemiInt to the FADC Mode 7 from Mode 3 -- Done on April 29, 2014. This mode provides:
- Pulse integral (sum of all 4ns samples over set threshold, up to 3 pulses per window)
- Pulse time (62.5 ps resolution)
- Pedestal average of 4 samples at beginning of window.
FADC Programmed Thresholds:
- Mott_Sample: Threshold = 0
- 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 CH9 - BFM Threshold = 1750 CH10 - Empty Threshold = 100 CH11 - Mott Trigger Threshold = 1000 CH12 - Empty Threshold = 100 CH13 - Delayed Hel Threshold = 10 CH14 - T_Settle Threshold = 10 CH15 - Pat Sync Threshold = 10 CH16 - Pair Sync Threshold = 10
Mott_Sample Settings: FADC_BLOCK_MODE = 1 MODE = 1 PL = 80 - Programmable Latency (100 ns to 8 µs) PTW = 50 - Programmable Trigger Window (100 ns to 2 µs)

Trigger Prescale
The input trigger can be prescaled by the ti:prescale parameter in the Configuration File
prescale = 0; /* Prescale factor := 1 / 2^<prescale> */

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

cedit and dbedit
Use cedit and/or dbedit to modify CODA database.
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.
