Design of Focus De-flection System for Tri-electrodes Electrostatic Deflection Type Cam-era Tubes.

In this paper,the structure for the focus deflection svs-tem of the electrostatic deflection type is studied and analyzed. This paper is to give the analytic solution for electrostatic focus.(rotary symmetry)and electrostatic deflection(non-rotary symmetry)field in cylindrical coordinates. The method is discussed of solving general equation of motion for an electron in the mixed field which is pro-duced by the combination of the electromagnetic focus field and the electrostatic deflection field. The optimum processing for twenty-eight derivatives of the potential function is performed by a matrix method. In the end,this paper presents calculation results for the test tube with electrostatic deflection type.
