Power-Cycling Mott DAQ VME Crate
We do NOT have remote reset for this crate. We tried these options but none is working now:
- Use APC http://g0injreboot.acc.jlab.org but after power cycling the crate remains in power-safe mode.
- At one time, we used minicom to hard reboot the Mott DAQ VME crate. This service was discontinued.
- We will try the RS232 connection on the CAEN VME64X VME8200.
Mott DAQ sbcmdaq0
Upgraded from MVME6100/VxWorks to Intel/Linux VME SBC. For more information, please see: [1]
MVME 6100 was replaced with a Concurrent Technologies VX915.
Local Operating System (CentOS 5.10) is installed on a Compact Flash (4GB) that is mounted on the module.
All DAQ software resides on NFS mounted directories from opsmdaq0.
From the idaq home directory, softlinks were made to /opt/coda/sbcmdaq0/linuxvme (contains an up to date version of the JLab module software drivers) /opt/coda/sbcmdaq0/rol (CODA readout lists for Mott)
Non-DAQ group software drivers were also ported to Linux to minimize software changes to be done on the analysis and monitoring side. These include:
- scalers (SIS3801, SIS3801.no_ring, intlib, scaser)
- v775
- v895
- helicity
To support the scaler library framework, a new library was written to facilitate the movement of data between different processes (scaler server, scaler producer, CODA ROC): crateSharedMem
All of these new libraries are located (and used) in: /opt/coda/sbcmdaq0/linuxvme/
The Scaler server and sisProducer are launched after boot via boot scripts in (sbcmdaq0) /home/idaq/boot_scripts/ via entries in /etc/inittab
CODA Readout Lists used in the 6100 were updated into the newer "C" readout list framework. No more using makelist or writing .crl files.
Scaler libraries were then optimized to support DMA.
All Mott CODA configurations are now ready to go:
- Mott_Sample
- Mott_SemiInt
- PEPPo_Int
- Scalers
The source is available here: /opt/coda/sbcmdaq0/rol
To compile, must be on sbcmdaq0. Use the Makefile.
To access the Mott DAQ VME SBC:
idaq@opsmdaq0 > ssh sbcmdaq0
Mott DAQ iocmdaq1
There are two ways to access the Mott DAQ ioc:
- From an accelerator machine: telnet iocmdaq1
- From an accelerator machine: ioc_concole iocmdaq1. Here you need to enter a password to this cannot be done with the idaq account.
The startup file: idaq@opsmdaq0:/cs/op/iocs/iocmdaq1/startup
# IOC: iocmdaq1 # Location: shellPromptSet("vxwrks@iocmdaq1 -> "); # Add the DAQ Host hostAdd "opsmdaq0","129.57.236.240" # Mount the CODA Distribution nfsMount "opsmdaq0","/opt","/opt" # Load CODA software and Drivers for Mott system cd "/opt" < /opt/coda/boot/mott_roc1.boot
The CODA boot file: idaq@opsmdaq0:/opt/coda/boot/mott_roc1.boot

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)
Mott_SemiInt Settings: FADC_BLOCK_MODE = 1 MODE = 7 PL = 80 PTW = 50 NSB = 5 - Number of Samples before the threshold crossing sample (TC) included in the pulse data set (integral) NSA = 28 - Number of Samples after the threshold crossing sample (TC) included in the pulse data set (integral) NP = 1 - Number of pulses to search for in PTW

Trigger Prescale
The input trigger can be prescaled by editing the crl file: /* Front panel trigger prescale: 2^<arg> */ tidSetPrescale(0);
cefdmp/xcefdmp
The event dump utility (cefdmp) can display, in a readable ASCII format, events from the data files.
Syntax
% cefdmp [filename] [-o object] [-t tag] [-u uniquetag] [-s start] [-e end] [-d dictionary] [-x] % xcefdmp [same]
Options
o specify the source object name (CODA component name) t select specified tag number or name (full path in event structure) u select specified unique tag, independent of location in the event s number of first record in file to dump e number of last record in file to dump d specify dictionary for obtaining tag names and titles x hex dump of integers (default is decimal)
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.
