SIMPLIFIED RESISTIVE LENS ELECTRON GUN WITH COMPOUND LINEAR VOLTAGE PROFILE

摘要

RCA 74,243AAbstractThe electron gun includes a pair of electrodesbetween which a resistive lens structure comprising a stackof alternate apertured plates and resistive blocks isdisposed. The stack comprises a first section which has tworesistive blocks between each adjacent pair of electrodeplates and a second section which has one resistive blockbetween each adjacent pair of electrode plates. The lens isthereby adapted to operate with a potential profile whichcomprises a compound linear slope in a 1:2 ratio.
