1) The mechanical design of the GBP must be integrated in the overall CAD of the LUXE experiment. Massimo will send the relevant files to Karsten (done!)
2) The radiation map in the experimental area is important to take decisions on the positioning of electronics (which is not rad hard). Louis should tell us when these maps are available.
3) The vibration in the experimental area have average values of 1um and frequency O(10 Hz). Important to minimize lever arms of the GBP supporting structure (Massimo)
4) Halogen Free cables in general not allowed  unless the halogen quantity is less or equal to 1l/100 m3 of air. We are needing microaxial cables 50 Ohm. About 1 km total length.
Karsten will look for solutions (At the moment we know only about not halogen free solutions)
5) Understand if we need to monitor humidity which ranges from 30% to 60% in the experimental area. This could impact HV discharge in the detector. (Mauro)
6) Kapton/Aluminum window of the beam line. Which material/thickness . Calculate the thermal stress to the window due to the beam (Louis)
7) Do we need dry air or Nitrogen to flux the Faraday cage? How many liters/hour? (Marco, Mauro)
8) Radiation doses in the environment as a function of the number of years of running should be known in order to properly plan human maintenance intervention in the GBP area.(Louis)
9) Something forgotten/misunderstood?

09:00 → 09:20 Mechanics Design status and next steps
