Read the complete Shifter Instructions¶MCenter Control Room (MC-CR) x3726 or x8871
- Call the Main Control Room at the start and at the end of shift. This is required, and pleasant.
- If the beam goes away for more than a few spills, look for Accelerator Alarms in ACNET (a default window). If the problem persists a few minutes, and you see nothing about it in the MCR elog, (or you just really want to find out more), call the MCR. They're friendly, though they may be super-busy.

Shifter, use these¶
- LArIAT Run 1 DAQ Instructions (March 2015)
- LArIAT Engineering Run (Aug 2014) How to Run the Lariat Data Acquisition (OBSOLETE)
- Run the Wire Chamber mini-DAQ
- LArIAT e-Log For making/ending access, starting/ending shifts.
- How to control and monitor PMT HV
Shifter, look at these¶
- Beam Monitor Display
- Operations Elog
- How to make DQM plots
- How to make Lariat DAQ Plots
- MC7 WebCam
- MC-7 Enclosure Layout
- If your Kerberos username and password are good, but you can't log on to FTBFLX[NN] machines: Have someone who CAN log into those machines heck that your kerberos principal appears in
~ftbf_user/.k5loginin the LArIAT section.
- If you cannot ssh to FTBFLX machines: Get a kerberos ticket for yourself, then ssh ftbf_user@ftbflx01 (or whichever machine...).
- If the wire chamber mini-DAQ is skipping spill numbers, it may be a high trigger rate (> 30 k per spill). The wire chamber controller may still be reading out the hits from the last spill.

Examining the WC mini DAQ ASCII data¶
The Processor makes TTrees from the ASCII files saved by
WC MiniDAQ Data Processor
Data files for various beam conditions can be found in the DataFiles page.
