FLNR STAD Scientific Seminar

On Friday, 8 April 2016, at 11.00 am in FLNR (bld.131, room 250, second floor) a seminar “MAIN MAGNETIC FOCUS ION SOURCE: Basic principles, theoretical predictions and experimental confirmations” will be held.

Speaker: V.P.Ovsyannikov (Hochschulstr. 13, D-01069, Dresden, Germany)

Abstract:

It is proposed to produce highly charged ions in the local potential traps formed by the rippled electron beam in a focusing magnetic field. In this method, extremely high electron current densities can be attained on short length of the ion trap. The design of very compact ion sources of the new generation is presented. The computer simulations predict that for such ions as, for example, Ne⁸⁺ and Xe⁴⁴⁺, the intensities of about 10⁹ and 10⁶ ions per second, respectively, can be obtained. The experiments with pilot example of the ion source confirm efficiency of the suggested method. The X-ray emission from Ir⁵⁹⁺, Xe⁴⁴⁺ and Ar¹⁶⁺ ions was detected. The control over depth of the local ion trap is shown to be feasible.
