All 3 detectors working

Detector A: High Voltage = 1900V; Threshold = 5mV

Detector C: High Voltage = 1860V; Threshold = 10mV

Detector D: High Voltage = 1950V; Threshold = 5mV

Note: Really high background in the experimental cell, so more shielding was added: i.e. paraffin wax.

Before shielding:
