Interposed therebetween is an accelerating electrode and a further electrode interposed between the accelerating electrode and the photocathode. The accelerating electrode is supported opposite the photocathode by a distance equivalent to the longitudinal length of the further electrode. The further electrode is maintained at the same potential as that of the photocathode.
