Abstract
The present invention is directed to a bipolar ion detector capable of detecting both positive and negative ions in a single configuration. The invention uses either a single microchannel plates or a stack of microchannel plates to convert the ion signal into an amplified electron signal. Circuitry allows the anode to be biased (floated) to a positive high voltage and efficiently couple the signal from the anode out to recording electronics at ground.
