   Abstract:
   A gam­ma-ray beam pro­duced by Comp­ton scat­ter­ing of a laser beam with a rel­a­tivis­tic elec­tron beam has been used to de­ter­mine the elec­tron beam pa­ram­e­ters. In the past, the elec­tron beam en­er­gy and en­er­gy spread were di­rect­ly fit from the high en­er­gy edge of a mea­sured gamma beam spec­trum using a gam­ma-ray de­tec­tor. How­ev­er, due to non-ide­al re­sponse of the de­tec­tor, the mea­sured spec­trum can­not rep­re­sent the true en­er­gy dis­tri­bu­tion of the gam­ma-ray beam. Thus, the elec­tron beam en­er­gy and en­er­gy spread could not be ac­cu­rate­ly de­ter­mined from the mea­sured gamma beam spec­trum. In this paper, we will pre­sent a novel end-to-end spec­trum re­con­struc­tion method to ac­cu­rate­ly ex­tract the en­er­gy dis­tri­bu­tion of the gam­ma-ray beam from the mea­sured gamma beam spec­trum. Using this method we have ac­cu­rate­ly de­ter­mined the en­er­gy and en­er­gy spread of the elec­tron beam in Duke stor­age ring using a Comp­ton gam­ma-ray beam from the High In­ten­si­ty γ-ray Source (HIγS) fa­cil­i­ty.
