CHARM Update
  • Goal of the facility:
    • Complexmixed particlefieldpresentwithin the accelerators
    • Simultaneouseffect (TID, DD, SEE)
    • In the framework of the R2E project the testing of electronicequipment in a radiation fieldsimilar to CERN acceleratorsis crucial → Assure mid-long termoperationrequirements
    • Facility not onlyuseful for CERN accelerators but also for :
      • Groundlevel and atmosphericenvironment(neutron energyspectra)
      • Spaceenvironment(representative for the inner proton radiation belt)
    • Size of the test area (severaltens of m3):
      • Large objectscanbeirradiated
      • Evenobjects in operationwith services connected (power, cooling…)
      • Can also host satelittes, part of cars or planes.

  • Implementation
    • Hypertack
    • 6 NE48 (RadTOL)


  • Schedule:
    • We are on the way → around 2 monthsbeforegetting first beam → Everypieces/blocks/systems of CHARM are building/mountingeachday.
    • Commissioningshouldstart in August.
    • OperationshouldstartduringSeptember up to the 8th of December.
  • In order to prepare the CHARM operationschedule, the beam time requestform has been sent to the RadWGlist and externalusers.
  • For the moment someusers (alsoexternal) showedinterest of suchfacility (e. g. BNL, LHC experiments etc…)
  • FromRadWG, I have not yetreceivedanyfilledform.
  • Anycommentsregarding the beam time requestform ?
  • Information:
    • The new websiteisavailablehere
    • You canalsofind information about the availablecables on-site.
