Day Shift Program

Following is the program for this monring:

— DUT( 2Col,50um) x-Position Scan —

  1. Keep the Trigger Rates from the current run as the reference. ~10Hz (screenshot in “Print” folder).
  2. Measure current position of Trigger counter-2.
  3. Put marker on the DUT at Laser height.
  4. Remove the trigger counter-2
  5. Relocate trigger counter-2 between LGAD-5 and MCP-PMT
  6. Measure x-position of the DUT

— post trirger counter position change —

  1. X-check rates after the trigger counter-2 relocation. Fine tune alignment until we reproduce coincidence trigger rates of ~10 Hz.
  2. Execute DUT x-position scan (0, -3, +3, -6, +6, 0mm) : Actual entry for this sequence 0 → -3.0 → +6.0 → -9.0 → +12.0 → -6.0

— Aligntment optimization — Fine tune alignment relative position of trigger counters, trackers, and DUT.

— DUT( 2Col,30um) x-Position Scan —

  1. Remove DUT( 2Col,50um) from Line-2
  2. Take 1hour run without DUT @ nominal position (x=0)
  3. Take (2Col30um) sensor out from Line-3 and install (4Col30um) to Line-3.
  4. Install (2Col30um) sensor to DUT in Line-2.
  5. Repeat x-Pos scan (0, -3, +3, -6, +6, 0mm) : Actual entry for this sequence 0 → -3.0 → +6.0 → -9.0 → +12.0 → -6.0
