Removing The Photodetector (PMT) Assembly

When required:

Faulty photomultiplier

Tools required:

Allen keys
Lint-free optical lens tissue

Parts required:

Photo Detector Assembly (# 0860-0580)

Electronic boards and components are sensitive to 
electronic discharge (ESD). In orde r to prevent damage 
always use ESD protection when handling electronic boards 
and components.

1) Open the detector’s side panel 
using the access key, as shown.

2) Locate the PMT module on the 
optical assembly, as shown.
