DESIGN OF THE SHIFTING SECTION OF AN INTENSIFIER SILICON TARGET PICK-UP TUBE

In this paper, the principle of design of the shifting image section of an intensifier silicon target pick-up tube is given. An electrostatic electron-optical system with a photoca-thode having an effective diameter of 40 mm and a system magnification of 0.65 has been designed. The experiments show that when the electron image of the photocathode is tran-sfered to the silicon target, the geometrie distortion is only 2%, the field curvature is 2 mm. The astigmatism is less than 0.32 mm at 80 percent of the viewing field and the resolution is over 50 1p/mm. It shows that the design of the electron-optical system is good and reasonable.
