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.
