Proton Calorimetry/Experimental Runs/2022/MayLED
Optical isolation tests using LED fibre in D27.
Aim: Investigate optimal material to use to optically isolate unpainted sheets and whether single layers of material provide sufficient isolation.
Notes
- DDC232 settings: 170us integration time and measured 10000 samples per run.
- Signal Generator settings: 0 ps delay, 500 kHz, 300 ns width, 5 ns leading edge and trailing edge, 6V high, 0V low.
- Fibres used: 25 and 29 (25 used for single injection tests).
- Sheets used: 84, 82, 81, 80, 79, 78, 77, 76, 75
- Materials tested: none, white paper (0.01 mm thick), black card (0.02 mm thick), mylar foil (0.006 mm thick). Materials cut into 10 cm x 10 cm layers and placed in-between sheets.
