PREX Main<< HOW TOs


For shift workers

To launch the HV GUI

Image 1
  • Log in as aslow@adaqsc (ask for password/probably no need of password)
  • cd into slowc directory
  • run ./hvs PREXR for RHRS HV GUI
  • run ./hvs PREXL for LHRS HV GUI
      • Note: If the HV GUI is already running in some other computer, it will ask if you want to kill the running process (see Image 1). You can type y and hit Enter. This will just kill the pre-existing GUI but will not affect HV settings and status.
  • Choose the desired slot
