A new photon counting, imaging readout for microchannel plate sensors, the cross strip (XS) anode, has, been investigated. Charge centroiding of signals detected on two orthogonal layers of sense strip sets are used to derive photon locations. The XS anode spatial resolution (< 3 μm FWHM) exceeds the spatial resolution of most direct charge sensing anodes, and does so at low gain (< 2 x 10(6)). The image linearity and fidelity are high enough to resolve and map 7 mum MCP pores, offering new possibilities for astronomical and other applications. (C) 2003 Elsevier Science B.V.
