The temperature dependence of the Kerr constant for water has been determined over the range 19°C-45°C at a wavelength of 658 nm. This paper presents the experimental arrangement used for this purpose and the data obtained, for which a polynomial fit is provided. A formula is also suggested to help estimate the variation of the Kerr constant for water with both temperature and wavelength.
By particle-in-cell (PIC) simulation and theoretically analysis, electron spatial distribution and energy distribution in the rod surface of rod-pinch diode(RPD) are obtained separately, as input parameters for Monte Carlo simulation of photon energy spectrum of X-ray emitted from RPD. The Monte Carlo simulation results show that the average photon energy of shot 09006 is 0.441 MeV. Taking account of Pb attenuator, the simulation results accord with experiment data detected by PIN detectors array.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
