Abstract
Abstract Self-scanned silicon diode arrays designed for light detection are now available commercially. Attempts have been made to use them in a Digicon type image tube but the signal produced appears to be too low for single photoelectron detection. At the last Symposium we reported experiments on a silicon diode having a charge amplifier integrated on the chip. These indicated that single photoelectron detection should be possible with a self-scanned array if a charge amplifier is provided for each diode (“Adv. E.E.P.” Vol. 33B, p. 873 (1972)). The development of a self-scanned silicon diode array image for spectrographic recording is now well advanced. It will have two parallel arrays each of 512 diodes. (Diode dimensions 200 × 40 μ 2 , pitched at 50 μ). The scan rate will be 1000 scans per sec. The paper gave a progress report on (a) the MOS chip, (b) the image tube, (c) the hard-wired electronic circuitry, and (d) computer control of data acquisition and data processing.
