Multiple Ionization of Metal Ions in SMIS 75
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 Pt2+ up to Pt7+.Maximum stripped observed ion is Pt10+.Total current of ion beam is about 300mA.
