This technique only gives time-of-flight of the fragments, consequently one obtains only one-dimension information of the fragment. In order to investigate the complete dynamics of ion-molecule collisions, it is necessary to develop a position-sensitive multi-hit detector system. The position information was obtained by using the wedge-and-strip anode with very good resolution.展开更多
