Claim 1
Independent Claim
116 words
A METHOD FOR DETERMINING THE THICKNESS OF AN INTEGUMENT ON A BASE MATERIAL UTILIZING THE KNOWN RELATIONSHIP BETWEEN RANGE AND ENERGY OF ELECTRONS PASSING THROUGH MATTER, SAID INTEGUMENT AND SAID BASE MATERIAL HAVING DIFFERENT CHEMICAL COMPOSITIONS, WHICH COMPRISES: DIRECTING AN ELECTRON BEAM AT SAID INTEGUMENT, VARYING THE KINETIC ENERGY OF SAID ELECTRON BEAM, DETECTING THE PENETRATION OF SAID INTEGUMENT BY SAID ELECTRON BEAM TO DERIVE AN INDICATION OF THE KINETIC ENERGY OF SAID ELECTRON BEAM AT WHICH COMPLETE PENETRATION OF SAID INTEGUMENT OCCURS, AND OBTAINING THE THICKNESS OF SAID INTEGUMENT BY RELATING THE KINETIC ENERGY OF SAID ELECTRON BEAM AT WHICH COMPLETE PENETRATION OF SAID INTEGUMENT OCCURS TO THE RANGE-ENERGY CURVE OF ELECTRONS PASSING THROUGH MATTER.
