Power-Cycling Mott DAQ VME Crate -- UPDATE

To power-cycling the Injector crates. This is necessary when ROC31 (aka g0inj) or ROC24 (aka happexinj) get hung up. Go to: http://g0injreboot.acc.jlab.org (parity, parity).

"sbcmdaq0" is connected to Outlet4. Click "Control Action" and select "Immediate Off", then click the "Apply" button. Wait a few seconds, then "Control Action" and "Immediate On" and "Apply".

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

CODA Files

CODA crl files are in: idaq@opsmdaq0: /opt/idaq/crl
Scalers.crl
Mott_Sample.crl
Mott_SemiInt.crl
PEPPo_Int.crl
To compile: makelist Mott_Sample.crl ppc

CODA scripts files are in: idaq@opsmdaq0: /opt/idaq/scripts

Summary of CODA Configurations

Name	Readout	Output	Trigger
Scalers	Scaler S1 (helicity gated), S2 (un-gated)	Scalers_%d.dat	Delayed nT_Settle
Mott_Sample	Mott FADC, S1, S2, TDC	Mott_Sample_%d.dat	Mott Detector
Mott_SemiInt	Mott FADC, S1, S2, TDC	Mott_SemiInt_%d.dat	Mott Detector
PEPPo_Int	INT FADC, S1, S2	PEPPo_Int_%d.dat	nT_Settle

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)

TDC

 CAEN v775
 const int V775_ADD    = 0x1190

 From Coda file:
 Full Scale (ns) = v775_getFSR() = 134 ns
 Bin Resolution (ps) = (v775_getLSB()*1000.) = 34 ps/channel

 vxwrks@iocmdaq1 -> v775_printScaleInfo()
 v775 => fullscale register =255 (0xff), LSB=0.034902 ns/chan, full scale=134.023529 ns, sliding Gate=1

 The TDC is operated in Common Start Mode: v775_setupCommonStart()

TID

 A24 Address for TID Module (0x100000 for VME Slot 2)
 const TRIG_ADDR       = 0x100000

Reference: Media:TImaster.pdf

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.
