A beam line for HERDA (High-resolution Elastic Recoil Detection Analysis) was developed in the D-course of 1 MV Tandetron accelerator in UTTAC, Univ. of Tsukuba. The 500 keV 16O+was selected as the incident beam after a result of investigation of the suitable incident ion beam from the viewpoint of available current and cross section for ERDA. The 300 nA, φ1 mm 16O+beam was obtained on a target. The energy of the recoiled 1H+ion (the recoil angle is set at 30 degree) was analyzed by 90 degree magnet. In this project, the 90 degree magnet with the radius of 200 mm and electrostatic quadrupole lens put in front of the magnet were prepared. The energy of the recoiled ion is determined by the PSD (Position Sensitive Detector) consists of the micro channel plate and the resistor array. The fundamentals of the developed beam line was checked by using the hydrogen-terminated Si(100) as a sample.

在筑波大学UTAC的1 MV串列加速器的D-程上，研制了一条用于高分辨弹性反冲探测分析（HERDA）的束线。从ERDA的可用电流和截面的角度出发，对合适的入射离子束进行了研究，选择了500 keV的16 O+作为入射离子束。在靶上获得了300 nA，φ1 mm的~（16）O ~+束流。通过90度磁体分析反冲的1H+离子的能量（反冲角设定为30度）。在本项目中，制备了半径为200 mm的90 °磁体和置于磁体前的静电四极透镜。由微通道板和电阻阵列组成的位置敏感探测器（PSD）确定反冲离子的能量。以氢封端的Si（100）为样品，验证了所发展的束线的基本原理。
