Abstract :
The factors affecting the performance of a position sensitive timing detector (PSTD), based on the detection of secondary electrons ejected from a foil by the passing ion, were investigated. We studied effects of multiple scattering in the foil, electron transport from foil to micro-channel plate detector (MCP) surface, and signal processing hardware. We conclude that, for detector with foil-to-MCP distance of 5-10 cm, electron transport limits the devices currently in use to resolution worse then 2 mm (fwhm)
