Fermilab Test Beam Run¶

Shifter Roles¶

• Leader: Communicate with MCR regarding desired beam energy and other relevant details. Manage the DAQ (start and stop runs)
• Remote: Keep a shift log of actives during the shift. Decode runs as they are completed. Post a shift summary logbook entry at the conclusion of your shift.

VNC Connection Information (for Remote Shifts)¶

• Using terminal, ssh into login and then the computer that has the VNC server on it
  ssh -L 5901:localhost:XXXX janedoe@fnalu.fnal.gov
  Replace XXXX with a port number of your choice (avoid 22). Log in using your credentials

• In the same session, ssh to the computer:
  ssh -L XXXX:localhost:5901 a-compton@clrlpc.dhcp.fnal.gov
  Log in using JLab CUE credentials for user a-compton.

• On your machine, run the VNC application. When prompted for the VNC Server, use: localhost:5901
  Encryption: Let VNC Server choose
  Enter password set up on the VNC server
  Log in using your credentials

How to make beam position plots using the MWPC data¶

Directions below are for the soliddaq.dhcp.fnal.gov machine.

The MWPC folder is located at: /home/a-compton/MWPC/
Raw data at: /home/a-compton/MWPC/data
decoder at: /home/a-compton/MWPC/analysis/basic

A script to run decoder and make one figure of beam position is available here:

/home/a-compton/MWPC/analysis/basic/wcsolid.csh

You can run this script at any folder.
