• set up the SSH tunnel between the luxelab computer and the facet-srv20 we use the following command:
  
  • [fphysics@facet-srv20 ~/ivoschul ]$ ssh -F .ssh/config -N -f luxelab
  • -F defines the config file which is not at the default location, it defines
    • the users, key-pair, IPs, and proxyjump
    • RemoteForward 62882 localhost:62882
    • LocalForward 62883 localhost:62883
  • -N makes the session non-interactive
  • -f puts the session in the background
• to kill the session we can use the following:

  • [fphysics@facet-srv20 ~/ivoschul ]$ ps aux | grep 'ssh -F .ssh/config'

  • this will output three processes, one is the grep command and two are the ssh connections to the gate and to the luxelab
  • get the process ID of the connection to the gate and kill it with [fphysics@facet-srv20 ~/ivoschul ]$ kill processID

Run the Time Server

• create the tunnel between luxelab and facet-srv20 with the proper port forwarding (see above)
• log in to facet-srv20
• create or reattach the screen session (usually called ivoschul_timeSrv)
• run $ python /home/fphysics/ivoschul/timeServer.py
• log in to luxelab
• run $ /home/luxelab/LUXE320/control/timeClient/build/timeClient
• it should print the server and client times

Port Usage

• 62882 / 62883 → ports between luxelab and facet-srv20port usage:
• 62884 → Ivo's jupyter server on facet-srv20
• 62885 → daq server on luxelab
• 62886 → Antonio's jupyter server on luxelab

Machine/Beam Trigger

1. open facethome (from the control network)
2. navigate to the Experiment - LI20 section
3. select the Triggers... menu in the FKG20-24 section
4. our trigger is channel 2 in the front panel section, called trigger FP2
5. we use the following settings
   
   1. beam trigger (coming from trigger RP2)
   2. normal polarity
   3. 1000 ns width
   4. 10 ns delay
