MAGNETIC ELECTRIC DISCHARGE PUMP Russian patent published in 1994 - IPC

FIELD: acceleration technology. SUBSTANCE: insert produced from getter material is installed between pumped out vacuum chamber and electrode system of pump. Insert is manufactured in the form of parallel sorption-active elements 5 having thickness t. Lateral dimension r of pump, its height h and axial length 1 of insert are tied up by relations: r ≫ t , τ_oV_o/[(h-0,51)²+r²]^0,5 >1,, where τ_o, V_o are mean values of time of life and velocity of molecules of main component of gas mixture under excited state. Description of invention gives versions of manufacture of insert. Invention can be used for pumping out of particle accelerators and other electrophysical installations. EFFECT: enhanced speed of response, improved mass and size characteristics, prolonged service life with pumping out multicomponent gas mixtures. 7 cl, 1 dwg
