THE MEPSICRON (Microchannel Electron Position Sensor with time resolution) is a new high resolution large sensitive area imaging photon counter developed recently in an attempt to overcome some of the more serious limitations of existing devices. In this paper, a description is given of its basic principles of operation, and a report is presented of the results of extensive tests of its astronomical performance with the echelle spectrograph on the 2.12m telescope of the Observatorio Astronomico Nacional in Baja California. High sensitivity, spatial and time resolution and ultra low noise are the salient operational characteristics of the detector. On the basis of these results, a brief comparative analysis is presented of the MEPSICRON and other detectors in current astronomical use.
