Abstract

 IN THIS PAPER A REPORT OF SIMULATION AND CONSTRUCTION AND EARLY DEVELOPMENTAL STAGES OF A THERMIONIC ELECTRON EMITTER ALONG WITH ACCOMPANYING ELECTRON OPTICS INCLUDING ELECTROSTATIC LENSES NECESSARY FOR ACCELERATING ELECTRONS, PASSING THEM THROUGH APERTURES AND FORMING AN ELECTRON BEAM AS WELL AS MAGNETIC FOCUSING LENSES FOR INCREASING POWER DENSITY OF THE BEAM IS GIVEN. THE COMPUTATIONAL CODE SIMION3D8. 0 MAY BE USED TO CORRECT THE CANONICAL PROPERTIES OF ELECTROSTATIC LENSES AND CALCULATE THE IMPOSED VOLTAGES ON OPTICAL COMPONENTS OF THE ELECTRON GUN. IN THESE GUN A 0. 3 MM TUNGSTEN WIRE HAVING A SHARP EMITTING AREA AT THE TOP IS USED AS A CATHODE. A DIRECT CURRENT WAS USED TO HEAT THE CATHODE. AN ELECTROMAGNETIC COIL IS USED FOR FOCUSING THE BEAM ONTO THE WORK PIECE. WE ACHIEVED TO A BEAM WITH FINAL EMISSION CURRENT OF 212 MA AND FINAL RADUSE OF 1.5 MM.
