摘　　要：论述了TIA-450型碳离子加速器双脉冲形成线形成原理及计算方法.由Marx源引出微秒脉冲高压加载于加速器双脉冲形成线上,向双向传输,首先负电压经B lum-lein线向右传输到输出开关击穿输出负脉冲;而向左方向的负电压传输到开关击穿并形成全反射,输出一正脉冲.在二极管上首先得到一个负脉冲引出等离子体,然后形成正脉冲加速碳离子束,在靶材上形成强流脉冲辐照效应,应用于材料表面改性.In this paper, the transmission of high-voltage in double pulse forming line （PFL） is presented and the transmission voltage in the PFL is calculated. Electrical breakdown delay time and the breakdown rate of the gas switch are provided. Micro-second voltage pulse is transmitted from the PFL, then one positive pulse is generated following one negative pulse, and is loaded in the diode system. Carbon ion beam radiates on the metal for surface modification.
