【Abstract】 Three slices of Li Al target alloy, whose thickness is 2mm, 4mm and 8mm respectively, are irradiated in SPRR 300. The inner neutron flux distribution in these slices is measured during irradiating, and the self shielding factors of these three slices are calculated. The self shielding factors of calculation are 0.76, 0.55 and 0.30, respectively.更多还原
