GGM Integration Stefano Colafranceschi for the Frascati group in collaboration with Giovanni Polese and Filip Thyssen September 21, 2009 The gas monitoring system is based on small RPC detectors in a cosmic ray telescope whose working point (gain and efficiency) is continuously monitored online. The gas monitoring system is designed to provide determination of shifts in working point conditions. The GGM gaps are located in the SGX5 gas room, the charge response to cosmic rays is monitored for three subsystems fluxed with fresh, before purifiers, after purifiers gas mixes. 12 May 2018 S.Colafranceschi - GGM INTEGRATION 1

WHAT IS AVAILABLE TODAY WITH GGM IN THE PRIVATE NETWORK All Packages have been already tested in the public network DAQ system (XDAQ package) HV, I monitoring (PVSS package) P/T/TH gas sensors (LabView package) Data transfer tested in the public network From/to PVSS DCS to pico sensors through OPC From/to PVSS DCS to trial DB CMS_GAS_GAIN_DATA@DEVDB10 (many problems found!) From/to XDAQ to VME controller Data transfer that cannot be tested (easily) in the public network FROM XDAQ to PVSS (PSX package), expecting help provided by experts Data transfer that cannot be tested at all in the public network From/to PVSS DCS to official CMS DB OMDS ), expecting help provided by experts Once done last two steps;To test the beta version from the cms private network: login to lxplus.cern.ch, login to cmsusrX rdesktop cms-rpc-dcs08 (DCS computer with the daq, HV, I monitoring, environment monitoring) done done 12 May 2018 S.Colafranceschi - GGM INTEGRATION 7

Open problem PSX server cms-rpc-dcs-07 cms-rpc-dcs-08 XDAQ DCS PVSS “PSX server is supposed to send GGM daq value (streamer, avalanche monitoring and efficiency) from our XDAQ application to PVSS through a SOAP protocol” dst file ROOT file (adc spectrum) metadata HV, I monitoring Environment Daq variables RPC PSX This server is needed to export the variables from the XDAQ application, linux based, to DCS PVSS datapoints Outside cms network: any PSX server ready-to-use available, we have tried to setup it but encountered many problems, and at the moment it doesn’t’ work. Installed PVSS 3.7 Installed XDAQ WORKSUITE and PSX compiled package Communication problem with the PSX server, during the setup something was wrong; the expert L.Orsini suggested to use the central one. 2. Inside cms network the RPC PSX server is running, but encountered problems using it, it seems we have to be fully integrated to have access to this server. We expect from Gomez-Reino Garrido  (the expert) the possibility to use this server. 12 May 2018 S.Colafranceschi - GGM INTEGRATION 8

S.Colafranceschi - GGM INTEGRATION WHAT IS LEFT TO DO… Open problem: Developing/Debugging integration protocols (PSX) in the .cms network, what we have done: Installed PVSS/XDAQ WORKSUITE and PSX to setup a private PSX server Tried to use the central PSX server but no communication Open problem discussed with F. Thyssen, G. Polese and R. Gomez-Reino Garrido, we expect to use “easily” the central PSX server as soon as possible From/to DCS PVSS to official CMS database OMDS, thanks to G. Polese PVSS panel ready to be integrated in the main RPC shifter panel 12 May 2018 S.Colafranceschi - GGM INTEGRATION 9
