为拓展单粒子效应实验中可用离子种类及能量范围,在串列加速器上对高电荷态实验技术进行了研究。串列加速器上离子能量由加速器端电压和离子电荷态共同决定,在端电压一定的情况下,电荷态越高的离子能量越高。然而,离子穿过剥离膜后不同电荷态的离子剥离概率并不相同,在大于最可几电荷态后,电荷态越高,剥离概率越低,束流因为强度弱就更加难以引出。本年度针对高电荷态离子调试技术以及弱束流监测技术进一步进行了完善,获得了剥离概率
In order to expand the available ion species and energy range in the single-particle effect experiment, the high charge state experimental technique was studied on a tandem accelerator. The energy of the tandem accelerator is determined by both the accelerator voltage and the ion charge state. The higher the charge energy is, the higher the ion energy is. However, the ionic debonding probability of different charge states is different after the ions pass through the release film. When the charge is larger than the most chargeable state, the higher the charge state is, the lower the probability of delamination is and the more difficult the beam exits due to the weak intensity. This year for high charge state ion debugging technology and weak beam monitoring technology has been further improved, access to the probability of peeling
