Outline of Final Research Achievements

High-resolution ERDA was developed in 1 MV electrostatic accelerator in University of Tsukuba in order to investigate the hydrogen dynamics around the Pd surface. In the present study the improvement of limit of detection for hydrogen was made. This is necessary to study the hydrogen on metal surfaces in ultrahigh vacuum. At first, ion-secondary electron coincidence measurement system was developed. With the Al coating on the stopper foil, from where the secondary electrons are emitted, the dark current noise in MCP (Micro-channel plate) was suppressed down to 2% with keeping the efficiency of 79%. Second, a position sensitive detector with a moving Si detector was tried to remove also the stray particles by means of their eneries. As a result, the noise due to the both dark current and stray partices are significantly removed and the limit of detection for hydrogen of 3 x 10(power of 20)/cm(power of 3) was accieved.
