| الملخص: | Title screen Most Cherenkov experiments focus on detecting a continuous Cherenkov radiation spectrum, in principle, from the sub-THz/THz range to “soft” X-ray. However, in the recent experiment on the Mainz Microtron MAMI, Germany, the possibility of detecting quasi-monochromatic Cherenkov peaks was confirmed using a high-energy electron beam and a thin quartz plate. Such experimental results were compared with the polarization currents model results, and a fair agreement was obtained. In the chase for even better agreement between theoretical and experimental results, it was decided to try out the Geant4 toolkit. Therefore, this paper aims to present Geant4 obtained results and compare them with both experimental and polarization currents model’s calculations. The first tryout with pencil-like electron beams, i.e., conditions used in analytical calculations, gave rather bad results. However, more realistic Gaussian beams gave much better results, even comparable to the analytical model results. Moreover, the results obtained for both beams are significant in drawing conclusions and open many possibilities for future improvements Текстовый файл AM_Agreement |
