Abstract
THE OBJECTIVE OF THE PROPOSED PROGRAM IS TO INVESTIGATE THE USE OF COHERENT TRANSITION RADIATION TO MEASURE THE ENERGY OF ULTRA-RELATIVISTIC CHARGED PARTICLES. THIS RESEARCH IS IMPORTANT IN HIGH-ENERGY PHYSICS FOR THE DETECTION AND IDENTIFICATION OF THESE PARTICLES. THE RESEARCH CAN ALSO RESULT IN A PARTICLE-ENERGY DETECTOR FOR BEAM DIAGNOSTICS FOR BOTH HIGH-REPETITION RATE AND SINGLE-PULSE HIGH-CURRENT ACCELERATORS. THE DEVICE WOULD BE LOW COST AND WOULD OPERATE INSTITU WHILE CAUSING LITTLE OR NO PERTURBATION TO THE BEAM. WE WILL SHOW THAT THE ANGLE AT WHICH SOFT X-RAYS ARE EMITTED FROM AN ELECTRON CROSSING A PERIODIC FOIL STACK DEPENDS UPON THE ELECTRON'S ENERGY. ACCORDINGLY, AN ACCURATE DETERMINATION OF THAT ANGLE WILL IDENTIFY THE PARTICLE'S ENERGY. A SOFT-X-RAY LINEAR-DIODE ARRAY WILL BE USED TO DETERMINE THE ANGLE OF EMISSION ON A PULSE-TO-PULSE BASIS. THE PRINCIPAL INVESTIGATOR AND HIS COLLEAGUES WERE THE FIRST TO OBSERVE COHERENT TRANSITION RADIATION IN THE SOFT-X-RAY REGION OF THE SPECTRUM (1 TO 3 KEV). A BEAMLINE IS AVAILABLE FOR THIS WORK.
