Digicon

A digicon detector is a spatially resolved light detector using the photoelectric effect directly. It uses magnetic and electric fields operating in a vacuum to focus the electrons released from a photocathode by incoming light onto a collection of silicon diodes. It is a photon-counting instrument, so most useful for weak sources. One of digicon's advantages is its very large dynamic range and it results from the short response and decay times of silicon diodes.
