Use of Electron Beam Gun for Hard Rock Excavation

Abstract

A mobile, field-worthy electron gun was checked out in a very limited series of outdoor tests on a 6 ft. cube of granite. Test results confirmed all expectations. It was proven that x-ray shielding posed no problems. A mathematical model of the electron beam piercing process and thermal stress cracking was devised which is in reasonable agreement with observations.
