Abstract

A desirable goal in experimental astronomy would be to find a detector that can individually record the time and coordinate position of each input photon, regardless of its wavelength -- subject, of course, to unavoidable quantum-uncertainty restrictions. For certain spectral regions, photocathodes would come close to meeting these basic objectives if satisfactory techniques could be developed to individually record each emitted photoelectron. While perhaps not widely recognized, the first practical television camera tube, the image dissector, does an excellent job of detecting individual photoelectrons, since each electron which enters its aperture is multiplied by a comparatively large factor, typically 10⁵-10⁶, and appears almost instantaneously as a large readily-counted burst of charge in the output circuit.
