Abstract: A photoelectronic image tube usable as a high-speed shutter is being developed. The tube is a magnetically focused image intensifier, in which the photoelectron beam is made to pass through two metal meshes mounted a few centimeters from the photocathode. The first mesh acts as a control grid while the second serves as an auxiliary electrode. Its introduction increases the control sensitivity and makes the electron focus less dependent on the control mesh potential. Shutter tubes having an on-off control voltage range of about 3 v and a resolution of 15 to 18 line pairs per millimeter have been made. The loss of electron current due to the meshes is less than 20%. Curves are presented showing the electron penetration under various conditions of cutoff.
