Abstract：
A Simple Mirror Ion Source with 75GHz pumping (SMIS 75) has been created. The confinement system is a mirror trap with magnetic field in the plug up to 5T, variable length 15—20cm and mirror ratio 3—5. The plasma of metal ions is injected into the trap by a special vacuum arc minigun. Plasma heating is performed by the microwave radiation of a gyrotron (the frequency of 75GHz, power up to 200kW, pulse duration up to 150μs). The results of the experiment have demonstrated substantial multiple ionization of metal ions. For a metal with high melting temperature (Pt), heating shifts the average ion charge from Pt ²⁺up to Pt ⁷⁺. Maximum stripped observed ion is Pt ¹⁰⁺. Total current of ion beam is about 300mA.
