摘要
We describe a novel, charge centroiding, position readout, the spiral anode (SPAN) which combines excellent spatial resolution with very high count rate performance. SPAN is a planar structure of six electrically isolated electrodes. The ratio of the charges collected by the electrodes determines a two-dimensional position. The novel design allows the spatial resolution to be an order of magnitude better than the charge measurement accuracy. We present results from a prototype detector consisting of a microchannel plate stack in conjunction with the SPAN readout and discuss opportunities for the use of the SPAN readout with other photon counting detectors.
