Bremsstrahlung Characteristics of Thick-Target Applied in High Energy X-Ray Facility

  • Variety of X-ray facilities are widely used in many fields. One of its developing trend is to gain harder and more intense X-rays which are yielded by electron beam with energy above 10MeV and current above kA impacting on thick-target. Dependence of bremsstrahlung characteristics on beam parameters and target thickness are much concerned. The paper studies the selection of the thickness of the target, the bremsstrahlung photons intensity distribution along emergence angle as well as the bremsstrahlung energy spectra. Also, the dependence of X-ray intensity on beam emittance and size of beam-target interaction spot is given. The result reveals at the usual emittance, the decreasing rate of the X-ray intensity with decreasing spot sige is much slowe than that claimed by other references. The consistency between the simulation with experimental results shows that the EGS4 codes can be effectively used in High Energy X-ray facility study.

Abstract: Variety of X-ray facilities are widely used in many fields. One of its developing trend is to gain harder and more intense X-rays which are yielded by electron beam with energy above 10MeV and current above kA impacting on thick-target. Dependence of bremsstrahlung characteristics on beam parameters and target thickness are much concerned. The paper studies the selection of the thickness of the target, the bremsstrahlung photons intensity distribution along emergence angle as well as the bremsstrahlung energy spectra. Also, the dependence of X-ray intensity on beam emittance and size of beam-target interaction spot is given. The result reveals at the usual emittance, the decreasing rate of the X-ray intensity with decreasing spot sige is much slowe than that claimed by other references. The consistency between the simulation with experimental results shows that the EGS4 codes can be effectively used in High Energy X-ray facility study.
