A new-type charged particle spectrograph has been proposed and built up. It combines the property of the small magnet which can analyse the particle momentum with that of the semiconductor detector which has a higher energy resolution. As a result, the particle identification and the analysis of energy spectrum can be obtained simultaneously. In this paper, the design and structure of this spectrograph are described, some experimental results of using it in nuclear reaction studies are given, and its applications and characteristics are discussed. This kind of spectrograph is more simple and facile but possesses rather better performances.
