Determination of Optimum Materials Thickness for Converting E-Beam Energy into Bremsstrahlung X-Rays on a 10 MeV High Energy Electron Accelerator Using MCNP

The e-beam produced by the high-energy electron accelerator has a relatively small penetrating power. To increase power, converter must convert energy into bremsstrahlung x-rays. This research aims to determine optimum thickness of tantalum, tungsten, and lead as x-rays at 10 MeV accelerator. is determined using simulation with MCNPX software. source modeling an made in form flat plane size 120 cm distance 1 mm from converter. dimensions 160 24 its varies - 7.5 mm. Then two planar detectors are placed 2 front behind results show that for 2.0 mm, 1.8 2.8 respectively. maximum forward scattered 2.1137 MeV, 2.1287 2.1850 And conversion efficiency 21.137%, 21.287%, 21.850%, These can be used reference design
