Operating the VELO Vacuum System under beam conditions

Make sure the PVSS-project "VEDCS_VacMot" is running under "velo_user" on "vedcs02w". If not, start it. If "gedi" is not running, start it. Start via "Vision" the panel G:\velo\pvss\VELO_VacuumMotion\panels\VeloVacuum_UI_Main.pnl

  • Click on "Show Details/Hide Details" (left top) to get information of more/fewer vacuum meters.
 
  • The most important ones are the 4 red encircled ones: PE411 and PE412 give the pressure in the beam volume in mbar. The pressure in the detector volume of the VELO is given by PE421 and PE422.

The state "Ready for Beam" is a combination of a several conditions, some of which can be overruled via a so-called "ignore"-action. This can only be done at the PLC-screen and is password protected. So if the vacuum system is not in the state "Ready for Beam" you cannot do much about it. The following information is there to help you to find the cause such that you can better judge what to do and/or who to call. Below it is assumed that no "ignore"-actions have been taken. "Ready for Beam" is defined as an AND of the following conditions:
