QADC spectrum

QADC Analysis

The first test for the detector signal after installing U-233 is by using CAEN V792 QDC (Analog charge to digital converter). The aim of this test is to test the shutter ability to help in distinguishing the emitted particles from U-233 source based on liberated charge from their ionization in gas.
