Detector Service the critical components of the electronic circuit and the
PMT/Crystal Assembly are aligned before leaving the
factory. If any component of the Scintillation Detector
is adjusted or replaced, the performance of the entire
system will be adversely affected and will require
realignment before continued use is possible.
Therefore, the scintillation detector IS NOT field
serviceable. Should a problem arise with the detector,
the entire Detector Assembly should be returned to
Ronan for repair/replacement.
