TIME-RESOLVED X-RAY SPECTRUM DIAGNOSTIC FOR FLASH BREMSSTRAHLUNG GENERATORS

THE GOAL OF THE PROPOSED RESEARCH IS TO INVESTIGATE TWO PROMISING APPROACHES FOR THE TIME-RESOLVED MEASUREMENT OF BREMSSTRAHLUNG IN THE RANGE OF ? 1 MEV ENERGY. ONE IS A MAGNETIC X-RAY DIODE (MAGNETIC XRD) WHICH EMPLOYS A MAGNETIC FIELD TO PROVIDE ENERGY DISCRIMINATION OF COMPTON ELECTRONS PRODUCED IN THE DETECTOR BY THE X-RAYS. THE OTHER APPROACH USES CHERENKOV EMISSION IN MATERIALS WITH DIFFERENT INDEX OF REFRACTION TO DETERMINE THE ENERGY DISTRIBUTION OF COMPTON ELECTRONS. THE RESEARCH OBJECTIVE IS TO DETERMINE THE SENSITIVITY OF THESE APPROACHES TO THE BREMSSTRAHLUNG SPECTRUM. PREDICTION OF THHE RESPONSE OF PROTOTYPE DEVICES WILL BE CALCULATED WITH COMPUTER CODES SUCH AS ITS. A PROOF-OF-PRINCIPLE TEST WILL BE PERFORMED.
