Test of the LV_Cutoff board for the Atlas Pixel system

Test of the LV_Cutoff board for the Atlas Pixel system

  • 4 identical sections that allow the passage of the power supply voltage between PS and Chip
  • Each section allows you to interrupt the power supply to the Chip by about 1.8V 10A, if an Interlock signal is activated.
  • Conditions:
    1) the Interlock signal is deactivated
    2) the PS supplies a voltage below 80mV.

PRT_2 board for Limadou2 PMTs

PRT_2 board for Limadou2 PMTs

  • Sensor: Hamamatsu R9880U
  • Limadou calorimeter with Plastic Scintillators
  • Critical issues:
    • Small PCBs/ high voltages : discharges risk
    • Outgassing
    • Thermal resistance (made with Kapton-Polyamide)
    • Redundancy (doubling capacitors)
