Proton Calorimetry/Experimental Runs/2020/Nov27
27 Nov 2020
Dark noise measurements in different rooms at UCL and with different conditions
Setup: - PD array exposed to dark - some runs have noise level recorded with PD unplugged
Aim: Measure the dark noise with different conditions. The spikes visible for all runs recorded inside D27 might come from noise
