Minutes of 3 June (taken by Paul)

Particle Peers

Choices to take:

• Materials / Thicknesses of absorbers
  • Technical drawings of rails
  • Brackets available or technical drawings
• Telescopes
  • Send around specs
  • Readout time
  • Number of planes
  • Simulation @Markus finds a G4 expert
• Data storage
• Analysis?
  • Add-on machine learning? @Cristovao

Computing:

• Analysis
  • EduSWAN (global SWAN, Jupyter notebooks)
• Data Storage
  • Options: NAF / desycloud / CERNbox
  • What do we store?
    • Raw?
    • Root?
  • Backed up please (NAF, desycloud, CERNbox)
  • Data transmission?
  • Copy data on a daily basis / convert to ROOT
    • Script executed by students?
  • Open access data storage?

Accounts:

• Maybe DESY computing accounts
• CERN accounts?
• Functional accounts for the students if (edu)SWAN will be used
• 4 PCs for analysis

DESY Chain:

• To decide:
  • Scintillation materials
    • Markus contacts experts/companies
  • PMT
    • which are the relevant wavelengths -> 400 - 550 nm for EJ-200
    • anything against the available 40 mm PMTs? -> No. Sune recommends using them
• To design:
  • Dark box
  • Optical coupling
    • Grease? Air? Optical gel?
    • Do we need a light guide? -> not for the organic scintillators. Decision for crystal pending
• Simulation:
  • G4 simulations: Does the scintillator (<10 cm) affect the electron beam

• Tracking (energy measurement):
  • In case of BRM usage:
    • Setup: Black box → 2-3 planes particle tracking (alpide?) → Magnet → MicroMegas → Trigger
    • @Paul ask Norbert for Laura’s beam support (tracking before the magnet)
    • Scintillators:
      • Large tails?
      • Mechanical support?
      • @Markus sends pictures around
  • In case of another magnet materializing:
    • Difference:
    • Potential of using DWC in case of not having Alpide ready

• Micromegas:
  • Need 8 MMFE8 cards (@Markus)
  • MicroMegas electronics cooling (@Markus)
  • Mechanical adjustment (@Cristovao)
  • Gas mixture → @Paul contacts Ralf / Baro
  • HV: brought from CERN (@Markus)
• Lead glass calorimeter:
  • Check DESY calo @Paul contacts Jan/Norbert
• VME readout:
  • SBCs:
    • One is at DESY
    • Spare will be prepared at CERN
  • Alpide:
    • Integration: @Paul contacts Yi/Lennart

• Homework for students:
  • Calculate synchrotron radiation → does it affect the experiment?

---++ Layout of the area:

• Challenges:
  • Moving the telescope (Monday morning it has to be reinstalled at the original position)
  • Material budget in front of the shower telescope / remove black box for shower experiment?
  • Different time slicing? Do scintillator experiment first and then the shower
  • Alternative setup: BRM → 1x MicroMegas → Shower telescope (can be moved out) → 1x MicroMegas

General:

• • Discuss spares (mechanics, detectors)
  • Analysis volunteers:
  • Find volunteers (J.H. Arling, Lennart, Yi, Uwe, Mengqing) @Paul
  • Use of Jupyter notebooks with ROOT → C++ or python? @Cristovao/@Paul
