8. Reconnect the ignitor cable to the Detector Controller.
10. Turn on the Detector Controller. Using WinPulse, reset the PMT voltage and
ignitor current to the desired set value.
Replacing the Optical Components
The three main components of the PFPD’s photomultiplier assembly that can be
replaced are the PMT, the optical filter, and the light pipe. These components are
shown in Figure 6.3.
Never use bare hands when installing the PFPD optics. Never handle tool parts
used to remove or replace internal parts of the detector. Always use clean latex
gloves and use Teflon-coated forceps to remove and replace internal optical parts.
Place optical parts on a clean, lint-free lab tissue or in a clean glass beaker, unless
otherwise stated.
