摘要
Recoil-ion momentum spectroscopy(RIMS)[1-3]is a very efficient technique to determine the charge state and the momentum vector of a recoiling target ion emerging from collisions between ions and atoms.However,the present RIMS techniques,typically employing gas target,are hard to efficiently obtain physical information of fast recoil ions in violent close collisions.A Fast Recoil-Ion Momentum Spectroscopy(FRIMS)with a new layout was designed to provide an efficient experimental tool to explore the dynamics of fast recoil ions.The recoiled ions with up to 2 keV energies are expected to be collected.The schematic drawing of the FRIMS is shown in Fig.1,the whole setup is operated in a high vacuum chamber.
