ELECTRODE FORM AND PRECISION POSITION

IT IS NOW FEASIBLE TO BUILD A THERMIONIC EMITTER (ELECTRON GUN) WITH 25 TO 50 TIMES GREATER PRECISION OF ELECTRODE FORMAND POSITION THAN HAS BEEN CONVENTIONALLY ACHIEVABLE. LEHRER-PEARSON, INC., (LP) WILL DO THIS BY USING A DESIGN CONCEPT (PATENT PENDING) THAT ALLOWS, FOR THE FIRST TIME, HIGH PRECISION CONTROL OF ELECTRODE FORM AND POSITION. WHAT THIS MIGHT DO TO IMPROVE BEAM QUALITY IS PRESENTLY UNKNOWN. LP PROPOSES TO USE MODERN MATERIALS AND STATE-OF- THE-ART PRECISION TECHNOLOGY TO CONTROL A SCHEDULE OF ELECTROSTATIC FIELD PATTERNS IN TEST GUNS. DATA FROM THESE TEST GUNS WILL BE USED TO DEFINE THE PRESENTLY UNDEFINED PORTION OF THE CURVE ELECTRODE PRECISION VS. BEAM QUALITY. IT IS IMPORTANT FOR DESIGN PURPOSES TO KNOW THE BREAK OF THEPRECISION VS. PERFORMANCE CURVE; THAT IS, WHERE IMPROVING ELECTRODE FORM AND POSITION PRECISION DOES NOT SIGNIFICANTLYIMPROVE BEAM QUALITY.
