- | GRETINA DAQ system | + | ======= FRIB online build window ====== |
+ | Issue the following command prior to starting the ReadoutGUI: export COINCIDENCE_TICKS=300 | ||
- | ====== HowTo for experimenter in charge ======== | ||
- | * Online SpecTcl [[:onlinespectcl|onlinespectcl]] | + | ======= Turn on/off Mode3 Data collection ====== |
+ | * To start/stop mode3 data collection on the EPICS GUI page click the button Cluster. In the newly opened window click the button **2 only** for mode2 data only or the **2 and 3** for both mode2 and mode3 data. | ||
+ | * Alternatively in a terminal on a2.gam run the command **"caput Data_CS_Save2And3 0/1"** to turn mode3 collection off/on. | ||
+ | * After doing this the decomp scripts should be modified as running the syncrofix command could overwrite this. | ||
+ | * For GRETINA standalone the script to modify is is **grdecompSA.sh** and for GRETINA-S800, **grdecompParticleGamma.sh**. | ||
+ | * For both scripts change the line **"caput Data_CS_Save2And3 0/1"** to turn mode3 collection off/on | ||
+ | |||
+ | ======= New in 2022 ====== | ||
+ | start run window is obsolete. Two scripts are available for changing the data directory. Daq needs to be stopped, directories need to exist: | ||
+ | * changeDataDir_maintainRunNum <data dir> : keeps the Run number the same, for when we need to move physics experiment data collection to another disk | ||
+ | * changeDataDir_resetRunNum <data dir> : finds the lowest available Run number without any larger RunDir #s | ||
- | ====== Changelog ======== | ||
- | ANY change to the DAQ system out here: [[:daqchange|daqchange]] | ||
- | **NOTE**: No change pass July 13th 2012 can be done without explicit | ||
- | announcement and approval (by Dirk). | ||
+ | ======= This is DAQ page from previous campaigns ====== | ||
+ | The DAQ page from the former S800-GRETINA campaign in 2012 can be found at | ||
+ | https://wikihost.nscl.msu.edu/gretina/doku.php/daq:daq_2012 | ||
- | ====== issues ======== | + | * S800-Gretina control [[docsS800Grt|docsS800Grt]] |
- | ANY issue/breakdown put here: [[:daqtrouble|daqtrouble]] | + | * {{ :daq:ulm-e16011_names.png?linkonly |S800 Trigger GUI}} |
+ | ======= Troubleshoot ====== | ||
+ | * S800-Gretina not correlated: Check CC setfile ~s800/converged_daq/Scripts/CC0105Begin.tcl for extsynch and extclock | ||
+ | * S800 is losing events. Check the network speed of spdaq32 by /sbin/ethtool eth0 and /sbin/ethtool eth1 , both should show speed as 1000Mb/s, if one shows 100Mb/s then the network is too slow and S800 cannot send data to GEB fast enough which will cause event loss happen. | ||
+ | * Check the ringbuffer status, $DAQBIN/ringbuffer status - -host=spdaq32 - -all , if the free colum becomes zero, DAQ related people needs to be notified for diagnostics. | ||
+ | ======= Decomp Information ====== | ||
+ | * [[easy_decomp_calibrations|Easy Gretina Decomp File Creation]] | ||
+ | * [[decomp_calibrations|Gretina Decomp Calibrations Explanation]] | ||
- | ReadOutShell reports "S800 changed to inactive" [[:ReadOutShellS800Inactive|ReadOutShellS800Inactive]] | + | ======= Gretina Computing ======= |
+ | Gretina computer farm is maintained by LBNL computer group and local NSCL IT department. Nonetheless I put documents here, but we do NOT do anything to the GRETINA computers! | ||
- | ====== start procedures ====== | ||
- | * [[GRETINA:GRETINA]] | + | * May 2019, documentation provided from Jackie: [[https://docs.google.com/document/d/1Aq5NkuEKBc4_5fx-95d2RaSZM08VQwVleYWr42QTsFg/edit?invite=CNr_nogM&ts=5cd488d9|Gretina System Documentation]] |

- | * [[daq:triggerconnection|Trigger connection (Card 29)]] | + | ======= Misc 2019 ====== |
+ | * Dual homed NSCL machines are spdaq32 and spdaq07 | ||
+ | ====== miscellaneous ====== | ||
+ | * Validation/Trigger window width is set by Dig116_CS_X55WidthP, Dig116_CS_X55WidthN. N/P stands for positive/negative maximum difference relative to Trigger timestamp which will be read out. | ||
+ | * Bringing up just the EPICs screen: in gretina home **./startGRETINA_EPICSdisplay** | ||
+ | * Set trigger multiplicity: **caput Trig0_CS_FSCThr n** (n=0,1,2,3... for mult 1,2,3,4...) | ||
+ | * See trigger pulse width: **CheckLED.sh** | ||
+ | * Change trigger pulse width: **SETLEDWIN <# of 20ns ticks>** | ||
+ | * Check timestamps, report boards that are out-of-sync: **CheckTS** | ||
+ | * Force timestamps to reset, DO NOT USE DURING RUN!!!: **SINGLEIMPSYNC** | ||
+ | * Warning script: run on a2 as gretina in ~/scripts: **./warningMessage4.sh ** | ||
+ | * Check decomp stats ** recordDecomp.sh | head -n50 ** | ||
+ | * [[Flash digitizer firmware]] | ||
+ | * Check digitizer firmware version: on a2 or a1 terminal, type: **DIGSNIDFW** ,all digitizers should have same version firmware | ||
+ | * [[Replace digitizer with different color ones]] | ||
+ | * [[Replace fuses of digitizer]] | ||
+ | * [[No valid decomposed events]] | ||
+ | * Verify connecedt digitizers, at IOC interface, type **dbior**, it will print all identified digitizers within one bank | ||
+ | * VME related scripts are located at /global/devel/boot/vmeArray | ||
+ | * Check connected PVs, at IOC interface, type "casr" | ||
+ | * [[ Move detectors to new Hole position ]] | ||
- | ====== Status ====== | + | ====== Reboot a2 ====== |
- | [[:status|status]] | + | * If a2 is rebooted due to system failure, two scripts need to be brought up |
+ | * from ~gretina: nohup scripts/warningMessage4.sh & | ||
+ | * from ~gretina/scripts/watcherdir: nohup watcher & | ||
+ | The first is the alarm script that talks to users. The second is responsible for two things: writing record{Counters,Decomp,Settings} in the current run directory and cleaning up cluster process issues (usually restarting broken processes) soon after starting or stopping runs. | ||
- | + | * Switch to a1 | |
- | + | * If a2 cannot be brought back. Gretina DAQ can still run on a1. In the file ~/.profile , environment variable **DAQSERVER** needs changed to be a1.gam . This parameter is used to restrict gretina daq critical scripts to run on specific machine. | |
