RESEARCH ON ELECTRON BOMBARDMENT INDUCED CONDUCTIVITY TARGETS IN CAMERA TUBES
Abstract
An analysis of scan parameters as they affect the performance of electron bombardment induced conductivity (EBIC) targets is presented. The conclusion is reached that the secondary emission characteristic of the target surface is an extremely important parameter in camera tubes of the photoconductivity and EBIC types. Evidence that the electron absorptivity of the target for low voltage electrons is affected by the degree of induced excitation is presented. Results of an investigation of different EBIC target materials are reviewed. The fabrication of experimental EBIC tubes having electrostatic and magn tic focused image sections is described. Test results are discussed.
