We have studied gain vs. voltage characteristics and position resolutions of multistep capillary plates (two or three capillary plates operating in a cascade), as well as capillary plates operating in a mode where the main amplification occurs in between the capillary plate and the readout plate (parallel plate amplification mode). Results of these studies demonstrated that in parallel-plate amplification mode one can reach both high gains (>105) and good position resolutions (similar to100 mum) even with a single step arrangement. This offers a compact amplification structure which can be used in many applications.
