      MC for GBP. Priority list

      LUXE

      1. Dose for the electronics placed nearby the gamma beam horizontal plane
        • (4/5) Kyle will prepare a neutrons map of irradiation of the area where the mini-crate is going to be placed.
        • (1/6) Kyle showed dose maps. There was an issue with horizontal x axis. Also, histograms binning is rather coarse due to the small number (300x300 ?) of bins for a large volume O(10^3 m3). (no link available)
        • (15/6) Kyle will present the fixed dose maps for (a) the GBP assembly volume and (b) the region near the pedestal where the electronics will be placed.
      2. Hadronic interactions on the profile reconstruction
        • Results: energy deposited is 30% higher. Main conclusions of the TN still valid.
      3. Best distance between the I and II station (min/max distance d_1, d_2)
      4. Check that 10um W foil in gamma spectrometer is included in lxsim [yes]
      5. Check that 200um Kapton - Al window at the beam pipe exit window in accounted [yes]
      6. Thermal stress on the detectors and on the beam pipe exit window (200um Kapton/Al)
        • Not a problem for the Kapton (link101) (link102). Therefore, thermal stresses on the sapphire detectors is expected to be neglibible.
        • However, temperature variations over time are important since they affect local charge carriers mobility in sapphire. A temperature map for a representative set of \xi values (i.e. \xi=3, 10) is necessary to evaluate this effect.
      7. Dynamic range of signals for the front-end electronics under LUXE typical operative conditions.
        • Effect on the resolution in reconstructing the beam profile
        • Estimate the range of signals to optimize the front-end electronics setup

      CLEAR

      For a general overview about CLEAR for our GBP, please check M.Bruschi status report here.

      Test beam at CLEAR is scheduled for 29/8-2/9 or 5-9/9. 

      Tentative deadline for the conclusion of MC jobs experiment-related may be the 22/8.
