Abstract

The Digicon detector, (in which accelerated photoelectrons are detected by solid state devices), has been used in various UV and visible photon counting applications, including the spectrographs in the Hubble Space Telescope'. Since the input photons are converted to electrons prior to detection, electronic image control such as gating, deflection and magnification is possible. A novel Digicon in which all three modes of image control are used has been designed. In this tube, magnetic deflection is used to randomly select a small area of the photocathode to be magnified for detection by a two dimensional diode array. Features of this design are presented along with preliminary data from demountable design-verification experiments. The data include magnified images in addition to the time dependence of the deflection magnetic field.
