Description
P
erkinElmer Optoelectronics, for-
merly EG&G Optoelectronics, is
pleased to introduce the Channel
Photomultiplier (CPM), a new ultra
high sensitivity optical detector
whichreplacesconventionalphoto-
multipliers (PMTs) and avalanche
photo diodes (APDs). This device
usesauniquedetectorprinciple,re-
sultinginacompactdesignwithul-
tra high gain, high dynamic range,
extremelylowdarkcurrent,andfast
response.

PrincipleofOperation
T
he CPM, like conventional photo-
multipliertubes,convertsaverylow
light level into photoelectrons by a
semitransparent photocathode de-
posited on the inner surface of the
entrancewindow.Ontheirwayfrom
thecathodetotheanodethephoto-
electronspassthroughanarrow,se-
miconductivechannel.Eachtimethe
electrons hit the inner wall of the
curvedchannel,multiplesecondary
electronsareemitted.Thiseffectoc-
curs multiple times along the path,
