Description
Provides the high voltage divider network for correctly biasing essentially all 10
stage photomultiplier tubes (PMTs) used for nuclear spectroscopy.
INPUTS | |
---|---|
HIGH-VOLTAGE PMT | Bias voltage. Range 0 to 2000 V dc. Anode and dynode series resistors, 10 Mohms. Bias network total resistance: 6.66 Mohms to 7.16 Mohms. |
OUTPUTS | |
ANODE OUTPUT | Provide negative polarity output from anode pin of PMT. Series high voltage blocking capacitor 0.01 uF. |
DYNODE OUTPUT | Provides positive polarity output from last dynode of PMT. Series high-voltage blocking capacitor: 0.01 uF. |
FOCUS | Range 72 to 145 V per 1000 V dc of high voltage input. |
GAIN | Anode bias range 92% to 100% of applied high voltage. |
