Expert Information
This page tries to capture/consolidate some low-level details in the Hall C Counting House configuration. In general every directory/system will contain one or more README files describing the relevant software/philosophy etc. The majority of the configuration files/code are also stored in git repos with remotes on the hallcgit.jlab.org host. Brad Sawatzky and Steve Wood set up a lot of this. Now, Bob Michaels and Chandan Ghosh are running the DAQ. I think this section may need updating.
Before becoming an expert, reminder on the basics: https://hallcweb.jlab.org/wiki/index.php/Hall_C_DAQ
- Hall C CODA/DAQ Layout
- General hardware and software layout of DAQ and CODA systems
- Some notes on how to change-over between experiments
- Hall C Trigger Layout
- Video capture systems
- Spectrometer Angle cameras
- Hall Cameras, etc.
- Hall C EPICS
- HV systems
- Gas systems
- Auxiliary softIOCs
- Hall C Compute Cluster
- Systems and layout
- Puppet configuration
- System backups
- Notes on spectrometer and cryo controls
- Monitoring and Alert Systems
- Munin: Temperatures, gas flows, computer systems, etc. Run

Detector/DAQ 'pre-beam' Checklist
This is a copy of the Detector/DAQ 'pre-beam' Checklist that is generally completed prior to beam delivery into the Hall (after a SAD or an extended down). It is intended to ensure that basic operational things like crate fans, crates, HVs, gas configuration, etc are confirmed and logged. This is typically requested by the Hall Work Coordinator (ie. Walter Kellner) and gets logged to the HCLOG. An example can be found here HCLog 3968308.
Print out two copies. One for HMS, one for SHMS: File:Detector readiness checklist.pdf, (File:Detector readiness checklist.ods)
Spare Hardware Locations
- CAMAC, NIM: Hall C Counting House cabinets (in electronics room by door to the outside)
- VME: Counting House, 2nd floor, blue module cabinet in Jack Segal's area
- HV: Counting House, 2nd floor, cabinet in "G0 cage"
- PMTs, HV bases: EEL/126 cabinet at rear of room (labelled, standard 'A12' keyed lock)
- Wiener Crate control units (front panel, ethernet, etc): EEL/126 cabinet
ESB / Building 23 (NE corner)
This has been my staging and test area for a number of years and contains several DAQ test beds supporting several groups. The hardware, cabling, modules in that space should generally be considered as either 'in-use' or as being staged for a near-term future experiment (ie. NPS/LAD/GEn-RP). The experiment on the floor takes priority, of course, but don't steal from future experiments without actively following up on replacing that hardware.
- CAEN Sy45xx crates and modules (NPS)
- Wiener VXS crates (NPS)
- FADCs, SD, TI, boards etc (NPS)
- Cabling (NPS, GEn-RP)
Spectrometer Magnets
- Magnet screen is brought up on any hcdesk machine by the command go_magnets
- Note: only ONE copy of the magnet control GUI screen can be running. Creating a new one will cause the old one to disappear.

- Do not use the milk frother; this will just get nasty. Warm up some milk in the microwave before running the machine.
- Regularly empty the drip tray and coffee grounds container.
- You can find a user manual and other information here
- The machine needs regular descaling; a warning light will tell us when. Instructions on how to do this are here.
