A G050700100014 4.6007g/cm2 thick gold metal foil of weight 0.05434g G050700100015 is wrapped with 0.025mm thick super pure Al foil in G050700100016 the case of 10MeV Bremsstrahlung G050700100017 DETECTOR (HPGE) Energy resolution of the detector is 2.0keV G050700100018 FWHM at 1332.0keV peak of Co-60. The detector volume G050700100019 of 80 cc coupled to a 4K channel analyser and 41.1 cc G050700100020 to a 16K channel analyser was used for 10 MeV and 8 MeVG050700100021 Bremsstrahlung irradiation experiment respectively. G050700100022 METHOD (ACTIV) G050700100023 INC-SOURCE (BRST) When an electron beam hits a 0.188cm thick Ta G050700100024 target, 8MeV Bremsstrahlung radiation was produced G050700100025 whereas 10MeV radiation was produced by impinging the G050700100026 electron beam on 1mm thick Ta target.
