Universal metal ion source

The metal ion source based on the magnetic trap with crossed fields (radial electrical and axial magnetic) is considered. This source formes plasma flow with magnetized heavy (metal) ions flowing along the longitudinal magnetic field. The self-supporting heavy ion discharge is existed in the source. The working substance is a cathode material which can be any conducting material. The operating principles and the features of the source are discussed. The plasma flows consisted of various metal ions (Cu, Ni, Ti) were experimentally obtained. The main parameters and the dependences of the titanium ion source are presented in detail. The typical parameters of this plasma flow are following: longitudinal velocity of 2–3×105 cm/s, ion transversal energy of 20–80 eV, average plasma density of 1012 cm−3; electron temperature of 40–60 eV; total ion current of plasma flow reach up to 3.6 A in pulse mode (discharge duration of 4–10 ms) of the source. The application of the source for plasma separation process is discussed.The metal ion source based on the magnetic trap with crossed fields (radial electrical and axial magnetic) is considered.
