RELICS PMT test data analysis

Guide

To install the package, run the following command in terminal:

git clone [email protected]:Westlake-University-Lsc-lab/RELICS_PMT_Data_Analysis.git

cd PolariserCheck

git checkout (branch_name)

Experiment

The setup of the experiment is shown in the box diagram.

Calibrations

Dark rate

Dark rate is tested every time HV is applied. A reasonable range is several hundreds of Hertz.

Polariser transmission ratio

Data is stored in the laboratory's server, analysised by this notebook.

Linearity

To find out the minimum energy for saturation, we tested the linearity of our PMT by comparing the pulse area of two PMTs.

Data was analysised by

Tests

Time constant of recharge

Dynode readout
