Getter Vacuum Pump

Element igp are closed pump.

Getter vacuum pump.

Systems fail to pump the main gaseous species in the system i e h2. Ion getter vacuum pump igp the ion pump operates between pressures ranging from 10 4 mbar to 10 10 mbar. Gettering is a vacuum pumping technology that has been with us in many forms for almost as long as vacuum technology itself has been in existence. No foreline only inlet whatever is pumped by igp will remain into the igp.

Vacuum creation with ion getter pumps. An ion getter pump consists of an array of positively charged parallel axis cylindrical anodes. Body and flange magnets. Getter pump or sorption pump in laboratory vacuum systems the bulk neg getter is often held in a separate vessel with its own heater attached to the vacuum system by a valve so that it can be replaced or renewed when saturated.

Their combination with a non evaporable getter neg. Ion pumps pressure range. For those applications igps remain the cleanest and most efficient method for achieving an ultra high vacuum. Nowadays igps with greater pumping speeds are mainly used within pressure ranges of 10 9 mbar.

Pump offering utmost sorption characteristics for h2 may therefore turn out to be useful when the overall pump ing speed and the ultimate vacuum have to be further im proved. Practical vacuum pump practice with dan herring vacuum pump practice with howard tring q s and a s what s hot newsletter glossary metallurgical terms getter materials by dan herring experience has shown us that sensitive materials in the presence of minute q contaminates can destroy the integrity and shorten the life expectance of componen. Ion getter pump uses a high voltage electrode to ionize the gas molecules and drive them into the getter surface. To the left and right of this array are twochemically reactive titanium plates whose normal vectors point along the axes of the anodes.

Ion getter pumps cas 2017. E mail vacuum demaco nl or call 31 0 226 33 21 00. Nonevaporable getter neg pumps are widely used for maintaining a clean ultrahigh vacuum uhv of 10 8 pa because of their high pumping speeds for hydrogen h2 and active gases in the uhv. Getter ion vacuum pumps are offered in diode and triode pump configuration.

Historically especially in the early days of electron tubes vacuum practitioners were concerned with clean up of the residual gases and needed to get them. Vacuum leak very unlikely if not. Cross section of the lep dipole vacuum chamber the main results are the following.
