  1. GEM based thermal neutron beam monitors

  2. Solution 1: Head on bGEM with back electronics – for testing Envelope space: Detector+Electronics (no cables or gas pipe considered) Gas Connectros 15 cm 6 cm 15 cm 13 cm Neutrons 13 cm Electronics in the beam This has been already realized and works well

  3. Solution 2a: Head on bGEM with side electronics Envelope space: Detector+Electronics (no cables or gas pipe considered) Gas Connectros Move front-end chips out of the beam 4 cm 20 cm Neutrons 20 cm Electronics out of the beam This solution should be developed and would be new FE Chips

  4. Sol 2 b:Head On bGEM with side electronics 4 Carioca Boards 64 channels First prototype with kapton pads No carioca board in the beam spot Only 2 mm of material budget SHIFT BOARD FPGA Matrix 8x8 Kapton Anode BEAM Pad Dimenrsion 8x8 mm2 2 mm 100 um matrix dimension 64x64 mm2

  5. Solution 2: Side-on bGEM TPC like Few borated slabs inside the beam 3D reconstrucion of the beam image Envelope space: Detector+Electronics (no cables or gas pipe considered) Gas Connectros 15 cm 13 cm Neutrons This dimension should fit the beam height 13 cm Electronics out of the beam This solution has been already partially developed

  6. Summary

  7. Cabling and Sensors • Alldetectors require • 2 Gas Pipes (in/out) – 6 mm diameter • Two T/P/H sensors both on Input and Output to monitor gas properties (temperature, pressure and humidity) • The sensors are contained in cylinders with a radius of 3 cm and an height of 10 cm and can be positioned where there is room • HV cable (1.5 cm diameter) • 16/32 Flat cables for front-end electronics • Each cable is 5 cm wide but the full envelope can be contained in a tube of 10 cm diameter A bGEM beam monitor based on Solution 1 will be realized next week Need all described infrastructures to be operated Sol2b will be realized as the next step Lenght of the cables to be determined
