Abstract
A NOVEL, HIGH THROUGHPUT, TITANIUM GETTER VACUUM PUMPING CONCEPT THAT UTILIZES THE KINETIC ENERGY IN THE PLASMA JET EMANATING FROM AN ARCJET ENGINE AS THE GETTER PUMPING POWER SOURCE IS PROPOSED. CALCULATIONS ARE PRESENTED WHICH SHOW THAT ARCJET ENGINES, WITH EXHAUST PLUME POWERS IN THE RANGE OF 20 - 60 KW, COULD BE OPERATED STEADY STATE FOR SEVERAL TENS OF MINUTES AT A BACKGROUND PRESSURE OF 5 X 10(-4) TORR USING THIS CONCEPT. THE ABILITY TO EFFICIENTLY GETTER NITROGEN OR HYDROGEN PERMITS APPLICATION OF THIS PUMPING CONCEPT TOENGINE PROPELLANTS SUCH AS AMMONIA, HYDRAZINE, AND HYDROGEN. A PROOF OF CONCEPT EXPERIMENT IS PROPOSED TO VERIFY THIS PLASMA JET SELF-GETTER PUMPING TECHNIQUE.
