Abstract

The article presents the results of measuring the luminescence of ambient air and a solution of an organic compound, when they are irradiated with a high-current pulsed electron beam with an average energy of Ee = 170 keV and a duration of 2 ns, formed by the RADAN-303 accelerator. It has been shown that under the action of UV radiation, the transformation of the Crystal Violet dye is only 2%. The addition of hydrogen peroxide leads to an increase in the phototransformation of the dye. The action of an electron beam on an aqueous dye solution is accompanied by a decrease in the intensity of air luminescence bands with an increase in the number of irradiation pulses. The results showed the degradation of both the dye itself and its transformation products under the action of an electron beam.

染料在电子束辐射下的发光
本文介绍了RADAN-303加速器形成的平均能量为170 keV、持续时间为2ns的大电流脉冲电子束辐照环境空气和有机化合物溶液时的发光测量结果。实验表明,在紫外辐射作用下,结晶紫染料的转化率仅为2%。过氧化氢的加入增加了染料的光转化。电子束作用于染料水溶液时,空气发光带强度随辐照脉冲数的增加而降低。结果表明,在电子束作用下,染料本身及其转化产物均发生降解。
