Monolithic integrated circuit (IC) detectors have been developed which consist of an array of electron sensing anodes and a corresponding array of amplifiers and counters all integrated onto a single chip. The anodes are fabricated on the surface of the chip over a thick dielectric film. The IC is mounted with a microchannel plate multiplier so that it counts individual charged particles and photons. The detector chip is so designed that it can be used in hybrid configurations. The active anode area can, therefore, be arbitrarily extended by abutting individual detector chips side by side, under the control of a customizing gate‐array chip. Quad‐detector chip sets are currently in use.
