Ultrahigh vacuum getter magnetic discharge pumps NWGM-2-1, NWGM-5-1.

UHV getter magnetic discharge pumps

NWGM-2-1, NWGM-5-1.

Designed to produce and maintain oil-free high and ultra-high vacuum (10-9 PA) during pumping active, including aggressive (arsenic, ammonia, chlorine, etc.) and inert gases in various process plants (molecular beam epitaxy, in the units of analysis of the composition and structures of the material).

Surpass characteristics similar pumps "Nord" NMD-0,4; NMDI-0,4;

and NMD-1; NMDI-1

Consist of magnetic discharge modules and resistive evaporators getter material, surrounded by a screen.

Equipped with power supplies magnetic discharge modules (open circuit voltage minus V, current short circuit 0.8 A – use one or two blocks) and resistive evaporators getter (voltage 10 V, current up to 65A).
