Abstract A recent experiment showed that a Cherenkov radiation spectrum from thin radiators with wavelength-dependent refractive index could transform into quasi-monochromatic spectral lines. Simulations based on the standard Geant4 toolkit not correctly describe experimental results because uses traditional Frank-Tamm theory developed for an ideal (infinitely thick) radiator. Because of that, we endeavor to present new way utilizing using newly models and comparing simulation ones. Now, one...
Abstract In light of our recent research, we discussed the possibility observing quasimonochromatic Cherenkov Radiation (ChR) spectral lines from a dispersive medium (thin quartz radiator). Such experimental results were verified on Mainz Microtron MAMI, Germany [1], while both polarization currents analytical model [2] and Geant4 [3] simulations used to analyze results. To describe radiation process, toolkit uses only approximation obtainable for an infinitely thick emitter (cos θ = 1 / βn...
Abstract In this paper, we propose to use quasi-monochromatic Cherenkov spectral lines for ion beam diagnostics. As representatives of light and heavy ions, C12 Au197 respectively. First, using the Geant4 toolkit, determine ionization lost energy as a function radiator penetration depth. After that, those data in polarization currents method compare theoretical with without losses. We also real-beam analyze setup parameters affecting accuracy emphasize that precision refractive index...
A layout for the investigation coherent Cherenkov radiation from a dielectric target with large spectral dispersion and diffraction conducting screen as tool non-invasive longitudinal electron beam profile diagnostics are proposed 20∼30MeV Linac at Shanghai Institute of Applied Physics (SINAP). In this paper status joint experiment future plans presented.
A recent experiment showed that a Cherenkov radiation spectrum from thin radiators possessing frequency dispersion could transform into quasi-monochromatic spectral lines. Simulations based on the standard Geant4 toolkit not correctly describe experimental results because uses traditional Frank-Tamm theory developed for an ideal (infinitely thick) radiator. Because of that, our endeavors in this paper are to present new way utilizing using Gneat4 models, while should be used as helping text...
In this paper we discuss the possibility of proof-of-principle experiment to observe backward transition radiation in EUV region as a first step for beam diagnostics. We have carried out simulations angular distributions molybdenum target different geometries. The simulation results are promising diagnostics purposes.
