APPLICATION TO BEAM DIAGNOSTICS AND PARTICLE IDENTIFICATION

THE OBJECTIVE OF THE PROPOSED PROGRAM IS TO INVESTIGATE THE USE OF RESONANCE OR COHERENT TRANSITION RADIATION FOR THE IDENTIFICATION OF HIGH-ENERGY PARTICLES. THE TECHNIQUES PROPOSED CAN BE USED FOR PARTICLE-MASS IDENTIFICATION OR FORBEAM DIAGNOSTIC AND MONITORING. TWO DEVICES WILL BE CONSTRUCTED. ONE WILL UTILIZE THE FACT THAT THE ENERGY THRESHOLDS OF VARIOUS RESONANT MODES OCCUR AT DIFFERENT ENERGIES. A FOIL STACK WILL BE DESIGNED WHICH WILL BE ROTATED ALONG AN AXIS PERPENDICULAR TO THE PARTICLE DIRECTION, ALLOWING SELECTION OF VARIOUS RESONANT MODES AND THEREBY DETERMINING PARTICLE ENERGY. A SECOND DETECTOR WILLBE DESIGNED AND CONTRUCTED WHICH ENHANCES THE ANGULAR RADIATION PATTERN OF THE X-RAY EMISSION. THIS WILL ALLOW A MORE ACCURATE DETERMINATION OF THE EMITTING PARTICLE'S ENERGY. BY ENHANCING RESONANT MODES WHICH EMIT AT ANGLES GREATER THAN 1/2, THE ENERGY OF THE EMITTING PARTICLES CAN BE DETERMINED AT LARGER VALUES THAN PREVIOUS DETECTOR SCHEMES.
