SIMPLIFIED RESISTIVE LENS ELECTRON GUN WITH COMPOUND LINEAR VOLTAGE PROFILE |
摘要 |
<p>RCA 74,243A The electron gun includes a pair of electrodes between which a resistive lens structure comprising a stack of alternate apertured plates and resistive blocks is disposed. The stack comprises a first section which has two resistive blocks between each adjacent pair of electrode plates and a second section which has one resistive block between each adjacent pair of electrode plates. The lens is thereby adapted to operate with a potential profile which comprises a compound linear slope in a 1:2 ratio.</p> |
