A New Laser Stripping Method by use of Multi-Photon Resonance Ionization Enhanced with Multi-Mirror System (RIMMS)

摘要

A new laser stripping method by use of multi-photon resonance ionization is proposed which is an advanced design of LUCE (Laser Undulator Charge Exchange) and DoLUCE (Double LUCE) for the next generation's proton storage rings. The new method utilizes a magnetic field to generate the Lorentz electric field on an H beam and to neutralize the beam. It utilizes also a visible laser light which irradiates the H~0 beam efficiently with a multi-mirror system in the central region of the magnetic field as like in the cases of LUCE and DoLUCE. In this method, the laser beam strips the electron of the H~0 beam almost completely by multi-photon resonance ionization. Thereby, the low emittance growth of H~+ beams after ionization can be achieved. It will possibly be realized with the existing technology.
