Paper Abstract

A 25mm. diameter, S25 photocathode, 10- pixel position sensitive photomatrix tube has been recently tested at the focus of the 2.12 m. telescope of the Observatorio Astronomico Nacional at San Pedro Martir in Baja, California. Direct imaging, high resolution spec-troscopy with a REOSC echelle spectrograph covering the 3200 - 6600Å range and high resolution spectroscopy with a scanning Fabry-Perot interferometer have been carried out on faint objects. Spectra of 13th to 16th magnitude quasars and galaxies have been observed with the MEPSICRON detector and satisfactory S/N ratios have been achieved in a few minutes exposure. Limiting total count rates, dark noise, linear spatial and time resolution were carefully measured in an astronomical setting. We present these results and briefly discuss their implication for fast, high resolution, large area imaging and spectroscopy of very faint astronomical sources.
