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. Plasma heating is performed by the microwave radiation of a gyrotron (frequency 75GHz, power up to 200kW, pulse duration up to 150μs). The first results on plasma creation, heating and confinement are presented. Gas discharge conditions and charge state distributions are investigated. The main features of the plasma are high density and short confinement time. Plasma is confined in the trap in quasi-gas-dynamic regime. This means very short rising time and very dense plasma flux.
