Determination of Optimum Thickness of Tantalum, Tungsten, and Lead as X-Rays Converter for 10 MeV Electron Beam Using MCNP | Chapter 6 | Fundamental Research and Application of Physical Science Vol. 3

 This research aims to decide the optimum width of tantalum, tungsten, and lead as a BXR converter at a 10 MeV high-strength electron. If the diameter is too thin, the change efficiency will be relatively depressed because the energized matter deceleration process apiece atomic nucleus of the preacher material is not yet maximized. An e-beam accompanying a finite penetrating capacity is produced apiece high-strength electron accelerator. The e-beam strength needs to be transformed into bremsstrahlung x-rays utilizing a converter to increase its seepage.  This optimum width provides best energy conversion adeptness. The simulation accompanying MCNPX software is used to decide the optimum thickness of each material. The power source is designed as a 120 cm by 10 cm flat plane at a distance of 1 mm from the preacher with an energy of 10 MeV. The preacher measures 160 cm by 24 cm and ranges in thickness from 1 to 7.5 mm. Two even detectors are then established 2 cm in front and behind the converter. The imitation results indicate that the optimum thicknesses for the tantalum, tungsten, and lead converters are 2.0 mm, 1.8 mm, and 2.8 mm, respectively. Furthermore, the maximum forward-scattered bremsstrahlung radioactivity energies are 2.1137 MeV, 2.1287 MeV, and 2.1850 MeV, individually, while the maximum conversion adeptness are 21.137%, 21.287%, and 21.850%, respectively. These findings can present image of a reference when plotting the converter for the 10 MeV extreme-energy electron machine for giving charged particles high velocity. The results can be secondhand as a reference in the design of the BXR preacher for the 10 MeV high-energy energized matter accelerator.
