The neutron generator is widely used in the fields of oil logging and element on-line analysis.The measurement of the transverse intensity distribution of the deuterium ion beam at the target position is of great significance to the improvement and optimization of the neutron generator.For Al_2O_3,SiO_2 and BGO scintillation screens used for transverse ion beam profile measurements,the temperature rises of the materials caused by 100 keV and 3 mm in diameter deuterium ion beam radiation was calculated with ...
