Description
It is required an ultra-high vacuum (near 10-11 Torr in the beam absence mode) in the synchrotron source of 4+ generation SFR “SKIF”. Owing to the vacuum chambers have small molecular conductivity and it exists the space limitation for pumps location, compact combined pumps application is required, i.e. pump on the base of non-evaporable getter and sputter ion pump. The modern pumps NEXTorr (SAES Getters, Italy) are not implemented the all of requirements on the inert gases such as argon and methane for SFR “SKIF”. Therefore, it is necessary to create similar combined pumps by Russian manufacture.
The first pumping speed calculations for one cell of triode type sputter ion pump and the whole of pump are presented here. Also experimental results of pumping speed measurements depending on the magnetic field, diameter and length of cell for sputter ion pump are given.
