Opis:: The Monte Carlo method based model of the ionization in the hot cavity taking into account radioactive decay of nuclides is presented. The code upgraded compared to the previous version enables calculation of the ion source ionization efficiency not only for different geometries and temperatures of the ionizer, extraction voltages etc. but also gives opportunity of setting different values of the nuclide half-life and its sticking time, which may be considered as the main factor determining the time that a particle spends in the ion source. The results of calculations are presented together with the discussion of the radioactive decay on the ion source performance.

Tytuł:: Modeling of Ionization in a Spherical Surface Ionizer

Opis:: A Monte Carlo method-based model of a hot cavity surface ion source with a spherically shaped ionizer is presented. A numerical code enables studies of ion source efficiency as a function of an extraction voltage, geometry of the ionizer and its temperature, the size of extraction aperture and many other factors. The calculation results for a variety of mentioned parameters are presented. A novel configuration of surface ion source is proposed and discussed - the efficiency of the source with an almost spherically shaped ionizer could be much higher than that of currently used constructions of ion sources.

Tytuł:: Ionization of Short-Lived Isotopes in Spherical Hot Cavities
Autorzy:: Turek, M.
Powiązania:: https://bibliotekanauki.pl/articles/1402238.pdf

Opis:: The numerical model of ionization of short-lived nuclides in spherical hot cavities is presented. Two different cavity configurations are considered: one of them (the hemispherical one) resembles that known from already existing ion sources while the other (closer to the full sphere) could be more efficient for short-lived isotopes. Changes of ionization efficiency with the half-life period as well as with the particle average sticking time are presented and discussed. Influence of the extraction opening radius on ionization efficiency is also under investigation.

Tytuł:: Effects of Electron Impact on Ionization of Short-Lived Isotopes in a Hot Cavity

Opis:: A Monte Carlo method based numerical model of hot cavity surface ion source that takes into account radioactive decay and the delay due to the sticking of particles to ionizer surface is considered. The influence of electron impact ionization by thermionic electrons accelerated by the extraction field is investigated. It is shown that the contribution from that process rises with decreasing half-life period and cannot be neglected, especially for substances of small surface ionization coefficient. The changes of relative yields from electron impact and surface processes with the length of the average sticking time are also studied.
