Claim 1
Independent Claim
136 words
IN APPARATUS FOR CONDUCTING ANALYSIS OF KNOWN ELEMENTS IN A SUBSTANCE DISPOSED IN AN EVACUATED SPACE WITH MEANS PROVIDED FOR DETECTING CHARACTERISTIC EMISSION FROM THE ELEMENT, THE COMBINATION COMPRISING A HIGH VOLTAGE SOURCE OF ELECTRONS, MEANS EXTENDING BETWEEN THE HIGH VOLTAGE SOURCE AND THE EVACUATED SPACE FOR ACCELERATION OF THE ELECTRONS INTO THE FORM OF A HIGH KINETIC ENERGY CONCENTRATED BEAM FOR DISCHARGE AT ONE END INTO THE EVACUATED SPACE, A MATERIAL ABSORBER LOCATED AT THE DISCHARGE END OF SAID ACCELERATING MEANS TO SCATTER THE BEAM INTO PARTICLE STREAMS OF ELECTRONS, A MAGNETIC FIELD PASSING ACROSS THE EVACUATED SPACE TO DIRECT THE PARTICLE STREAMS TOWARD THE SUBSTANCE, A PLATE INCLUDING AN APERTURE ALIGNED WITH THE SUBSTANCE TO INTERCEPT THE PARTICLE STREAMS, SAID MAGNETIC FIELD BEING OF A CONTROLLABLE STRENGTH TO SELECTIVELY DIRECT ELECTRONS IN THE PARTICLE
