FPM+FEE modules testing at Nevis Laboratories

• eLogs
• ToDoList:
  1. UPS setup
     1. Setup remote control with network card (support: Bill)
        1. ✔ Make connection (Bill sets up monitoring)
        2. ✔ Figure out remote controlling
     2. ✔ Connect: SiPMs PSU, Adapter PSU, PC, Fan, Function Generator, Laser driver
  2. ✔ Replace bias capacitors on SMART test board. See red circle in enclosed picture: 20201022_171019_MOD2.jpg (support: Nancy):
     1. C1, C3, C4: replace with 100nF, 100V (1206 package)
     2. C5, C6, C7: replace with 2.2uF, 100V (1206 package)
  3. Laser driver:
     1. Setup security switch on dark box
  4. ✔ PSU units:
     1. Write software for remote control. Basic functions: voltage r/w, compliance r/w, current r, enable control, channel select (for dual PSU)
        1. Software details written up in the 2020-12-09 eLog
  5. ✔ PC:
     1. Setup VNC server (support: Deivid)
  6. "Dark" tests:
     1. Connect Ham FPM to SMART + INFN Bari testing board; power up and look at scope signals
  7. "Light" tests:

Lab Setup

1. Connect 3 biases of 5V all from the same power supply (2 on the adapter board, 1 on the FPGA)
2. Connect HV SiPM to adapter board
3. Connections are mtx on the board, lemo on the scope
4. Organized in 4 rows, 2 for each SiPM tile connected

In the middle of the copper finger (towards the matrix) there is a hole to which the grey cube is screwed:

1. screw the cube on the copper finger
2. screw the matrix
