N1 - Funding Information: The several sputter ion pumps with the different magnetic fields and height and diameter of cells were tested in pressure range from 1E-9 to 1E-4 Torr. The pump with cells diameter 8 mm and the magnetic field 0,28 T looks very perspective. It is expected that specific pumping speed 34E-3 l/s/cm^3 for nitrogen can be obtained by choice of cell geometrical sizes and gap between anode and cathodes. The work was done at the shared research center SSTRC on the basis of the VEPP-4 - VEPP-2000 complex at BINP SB RAS, using equipment supported by project RFMEFI62119X0022.

N2 - It is required an ultra-high vacuum (near 1E-11 Torr in the beam absence mode) in the synchrotron source of 4th generation SFR “SKIF”. Owing to the vacuum chambers have small molecular conductivity and 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 argon and methane for SFR “SKIF”. Therefore, it is necessary to create similar combined pumps by Russian manufacture. The first theoretical pumping speed calculations for one cell of diode type sputter ion pump and the whole of sputter ion 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.
