Abstract:

A photon-counting detector array utilizes a one-dimensional multiple element anode array is in proximity focus to the last plate of the microchannel array for collecting the electrons generated therein. A specific embodiment has 64 anode elements. A detector system is provided with separate charge amplifiers, and level discriminators for each anode element. The discriminator outputs can be serially read out to a digital computer. Alternatively or additionally, the discriminator outputs are accumulated in counters, and display electronics are provided which can include digital-to-analog converters for forming a display representative of the counts accumulated in each counter, and the total count accumulated in all the counters.
