Difference between revisions of "CPP DAQ/Monitoring Test Spring 2022"

Revision as of 16:22, 7 June 2022

Overview

These are plans for some short tests to be done prior to the start of data taking to establish that the DAQ and online monitoring systems are configured and working properly. This will be done in 2 parts:

1. DAQ Cosmic test: This will exercise the full DAQ and online monitoring systems using cosmic rays. It will ensure all detectors are being read out and that the data is being both stored properly on tape and passed through the online monitoring system.

2. Online Monitoring High Rate Test: This will pass raw data files through the monitoring system at high rate to ensure the online monitoring is working and that the new plugins function properly under high rate.

Schedule

Important dates

• Mon. May 9 : AI/ML models trained and installed on gluons (Andrew, Nikhil, David)
• Tue. May 10 : Drift Chamber Atmospheric Pressure Alarm active (Naomi, David, Hovanes)
• Thu. May 12 : FMWPC_online, and FMWPC_performance production histos and macros in GitHub (all)
• Fri. May 13 : AIEC run-sync'd HV control tested (Thomas, David)
• Mon. May 16 : halld_recon updated and plugins built (Alex)
• Tue. May 17 : DAQ Cosmic Test starts (let run until 5/19 or 5/20)
• Fri. May 20 : Online Monitoring High Rate Test
• Mon. May 23 : GlueX - software/analysis tutorial for students
• Tue. May 24 : GlueX - Collaboration meeting starts (ends 5/26)
• Mon. Jun 6 : CPP run starts

DAQ Cosmic Test configuration: May 17

1. Use the standard DAQ configuration for CPP.
2. Solenoid OFF
3. BCAL, CDC, FDC, TOF, FCAL, FMWPC, CTOF all on
4. Trigger: TOF, CTOF, BCAL-cosmic
5. Online monitoring, HOSS, and Incoming Data systems active
6. AIEC CDC dynamic control active (fully automated, not run-sync'd)
7. Establish run and allow to continue for ~2-3 days in order to gather large cosmic data set

Online Monitoring High Rate Test configuration: May 20

1. DAQ system OFF (data will come from pre-existing files)
   •  ?? Can we start DAQ but pause run and feed from file into DAQ's ET system??
2. Online monitoring, HOSS active*
   • HOSS configuration modified to write data files to scratch directories on RAID so they do not get transferred to tape
3. Run in high rate mode for 2-4 hours to ensure operation for normal run duration

AIEC planning

Questions/to-do things

• Check these instructions https://halldweb.jlab.org/hdops/wiki/index.php/Central_Drift_Chamber_Shift#Running_the_AI_for_CDC_gain
• Monitor CDC AI High Voltage Control
• Is the on/off switch active?
• Is RoboCDC all ready to start up when DAQ go is pressed?
• If we see a never-before-measured pressure, we should switch off the AI & use 2125V to increase our training data. We don't have any data below 97.5 kPa or above 102 kPa. We only need to do this the first time we get that pressure - one run at previously unmeasured pressure is enough.
• D1 temp is 26C now - hopefully will remain within trained range.

Actual plan

1. Thomas: share location of init script.
2. Naomi: find location of HV graph scripts.
3. Add the initialization instructions to the CDC HV scan instructions. It could be done during the 2125V run, or during Sean's detector checkout.
4. Redraw the relative HV graph after the HV scan. Hopefully it will be exactly the same as previously. Adjust the function if not.
5. Activate the AI after the detector checkout (if that is after the HV scan).
