GMDPROV server works now on the PBD DAQ. The servers stores the GMD data 4 channels for 60 shots (6 sec):


  • PBD.PHFLUX/TUNNEL.ENPULSEIC
  • PBD.PHFLUX/BDA.ENPULSEIC
  • PBD.PHFLUX/TUNNEL.ENERGYPULSE.FF
  • PBD.PHFLUX/BDA.ENERGYPULSE.FF

One can retrieve the channels by sending a request to the corresponding properties including the desired eventID:


  • TTF2.DAQ/PBD.GMDPROV/GMDPROV/TUNNEL.REQ.ENPULSEIC
  • TTF2.DAQ/PBD.GMDPROV/GMDPROV/BDA.REQ.ENPULSEIC
  • TTF2.DAQ/PBD.GMDPROV/GMDPROV/TUNNEL.REQ.ENPULSE.SPECT
  • TTF2.DAQ/PBD.GMDPROV/GMDPROV/BDA.REQ.ENPULSE.SPECT


general features


  • if 0 is sent then the most recent data will be retrieved.


  • if there is no eventID in the server the reply will contain error: ill format.
