Preparation and Requirement

Dosimetry

  1. Regular dosimetry (long term)
  • Requirement : CERN ID, level 1&2 safety course, radiological safety course (F), medical cirtificate
  1. Short term (temporary) dosimetry : Only once per year (max. 2 months)
* CERN ID, level 1&2 safety course

Safety course

  • level 1&2 Link
  • Radiological safety training EDH->Training Catalogue->Safety

Before test beam shift

  • Access Request in EDH (Select your shift area,(e.g. Blg.887 H6 and 0157-R-012)

CERN beam test DAQ set up and how to run

  • Run SRSDCS_1.5.4 from desktop
    • connect the system to the FEC 10.0.0.14 (/home/dateuser/Desktop/MMs_30sept_2014_DAQ/config/XXXXX), load configuration file sdc_FEC_14.txt
    • open SRSDCS program and connect to the 10.0.0.14, apply the external trigger and enable the data acquisition
  • Starting the program
    • ./mmdaq3_server (/home/dateuser/Desktop/MMs_30_sept_2014_DAQ/mmdaq3-server)
    • ./browser --online (/home/dateuser/Desktop/MMs_30sept_2014_DAQ/GUI)
    • From GUI, load the config file (e.g. /home...../Config/TestBeam_MMSW.../DAQ_config.xml)
  • Run (pedestal)
    • select Pedestals n Run type, check "write the file", start run (change trigger switch in rack)
    • check the quality
  • Run (physics)
    • check trigger switch,
    • load pedestal file, check "write the file", then select Physics in Run type
