Experimental Results on the Ion-Beam Excitation of Drift Waves in an Alkali Plasma

Ion-cyclotron waves are excited by cesium and potassium ion beams in cesium and potassium Q-machine plasmas. The ion beams are injected along the magnetic field with care to avoid beam transverse velocities. The observed ion-cyclotron mode frequencies are below those driven by electron currents. These resonant instabilities are convective in character with small spatial growth rates ki/kr ≃ 0.05. Plasma ion heating is observed and is consistent with a model in which mode amplitudes are saturated by diffusion effects.

Polycrystalline Metals

The sputtering ratio of polycrystalline metals as well as the amount of ion beam energy reflected from the target surface showed angular behavior which was not monotonic at large angles of incidence. The simple model which takes into account "close-packing" at the target surface and, consequently, more or less ordered shadowing of the surface atoms seems to describe the experimental results qualitatively.

The Impact

Experimental results on the impact of pulsed ion beam with parameters the pulse duration 80 ns, energy of 200 keV and current density 120 А/сm2 , pulse energy ~ 1,5 J/сm2 on the alloy Zr1Nb on structure – phase state of the alloy of zirconium Zr1Nb. It is shown that such irradiation leads to changes in the structure of the surface and the hardening of the material.
