PARTICLE SENSOR

摘要

A particle sensor comprising a plurality of detectors (7) arranged in an array of rows and columns. Each detector generates a pulse when activated by an incident particle. A plurality of pulse sensors (8), such as SQUIDs, are each arranged to generate an output signal when it senses a pulse from one of a plurality of detectors in a respective row or column of the array. Means (15) are provided for deducing the location of an incident particle from the output signals of the pulse sensors in accordance with a predetermined algorithm.
