MULTIPLE CHANNEL DETECTION FOR TIME OF FLIGHT MASS SPECTROMETER

摘要

An ion detector for a Time of Flight mass spectrometer is disclosed comprising a single Microchannel Plate (1) which is arranged to receive ions (2) and output electrons (3). The electrons (3) are directed onto an array of photodiodes (4) which directly detects the electrons (3). The output from each photodiode (4) is connected to a separate Time to Digital Converter provided on an ASIC (5).
