Development of an Ion Emitter with Hollow Cold Cathode

Ion physics forms the basis for numerous modern technologies and research directions such as microelectronics, material research, analytics or high-energy physics. The reason for the broad range applications of ion physics lies in the ions characteristics: -The ions possess a mass, which makes a direct energy transfer possible to the solid atoms (flexible energy transmission); -The velocity of the ions can be multiplied by multiple ionisations in usual electrostatic accelerator installations. -The ions interact also with the electrons of the target material; this reciprocal effect is speed dependent and particularly effective, if the particle speeds are comparable; -The ions transporting characteristics with itself, which correspond to their chemical elements, from which were produced; -The ions can overcome the Coulomb barrier at high speeds with the impact with the target atoms and cause a nuclear fusion, whereby it comes afterwards to a nuclear explosion and to sending of elementary particles; -The ions can be bundled to particle beams with high energy and impulse density and be used thus as tool for metalworking. Although ion physics is a basic science in the most diverse fields, it exists mostly not as independent Discipline, but as application method within other science ranges. The development in this area carried of some specialists, who are active in different specialist areas. The most important sub ranges of ion physics are the ion production, the ion beam forming and the ion beam guidance. These aspects are gathered in the Monograph from I.G. Brown (Aitken, 1989). In addition a number of other recapitulate works over ion sources was published For the sub ranges of ion physics it is characteristic that progress in this area is obtained by skill and experience by specialists and the results in the connection a physical reason experiences. This applies in particular to the ion source development (Domonkos, 1999; Pessoa et al. 2006). With the beam forming and guidance come more computer simulation into the play, in order to before-compute favourable geometrical arrangements. Because of the procedures complexity in the combustion chamber of an ion source and the sensitive dependence of the ion source points on the kind, geometry and fuel parameters of the ion source often the task exists to optimize parameters, to the beam forming empirically in ion physics, which we want to examine with a cold cathode discharges. The aim of the present studies was to obtain experimental observations about the main features of hollow cold cathode discharge in order to evaluate its capability of generating compounds in the plasma medium, by reaction between sputtered species from the cathode and radicals from the gas discharge.
