Scientific paper

An imaging system, capable of operating in a photon counting mode and applicable to the large space telescope environment was studied. From the solutions available a direct coupling between a double-proximity focused curved microchannel plate intensifier and a camera tube with unitary target gain (vidicon) was chosen. This imaging system fulfills the requirements for a space mission of long duration. The effects of space radiation and magnetic fields are considered, as well as fatigue effects, noise, weight, and power consumption.
