Optimization of Microchannel Plate Multipliers for Tracking Minimum Ionizing Particles

The progress in development of special Microchannel Plates for particle tracking is reported. The requirements of i) high spatial resolution, ii) high density of information and, iii) rate capability were found to be satisfied in a thick Microchannel Plate with a CsI coating operating in a focusing magnetic field. The measurements of the Microchannel Plate detection efficiency, gain and noise are presented for several detectors. The pictures of the passage and interaction of the high energy charged particles inside the detector are shown.
