摘要

The article presents a detailed characterization of the ionization process taking place inside a miniature MEMS-type ion-sorption vacuum pump,based on the Penning pump architecture.Influence of a variety of parameters on the discharge current has been investigated.These include: magnetic field,type of material used for the electrodes as well as horizontal and vertical dimensions of the micropump.It was found that the micropump works efficiently as long as the magnetic field is higher than 0.3 T,and the pumping cell's dimensions exceed lxlxl mm3.Best results have been obtained for copper and aluminum cathodes and low resistivity silicon anodes.
