Abstract: A crossed delay line (CDL) readout for use in conjunction with a z-stack of 40 mm diameter microchannel plates (MCPs) has been designed using standard transmission line theory. The CDL readout was subsequently wound and tested in various configurations to determine if the electrical characteristics followed predicted trends. The agreement was good. The optimized CDL and MCPs were then designed into a sealed tube format which could be manufactured with either a visible or ultraviolet photocathode. The components were assembled into a vacuum system version and tested. The prototype detector displayed 15 $mu@m resolution and a maximum deviation from linearity of 180 $mu@m over the 40 mm format.!2
