Paper Abstract

We have developed an intensified charge-coupled device (CCD) bialkali photocathode image tube, based on the incorporation of a thinned backside-illuminated CCD as the target anode of a Hubble Space Telescope design Digicon tube. The delicate construction of the CCD target required development of a special low temperature (<230°C) processing schedule. The technique required to desorb all gasses, process a visual photocathode with adequate quantum efficiency and still remain within the time/temperature constraints dictated by the CCD is somewhat different than that employed for the typical multi-alkali photocathode tube fabrication. These techniques may be applicable to other types of complex design tubes where processing at >350°C is not possible. We discuss the specific approach we followed in developing this tube.
