Rebuild\/retrofit triode pumps to get better physical ruggedness, lifetime and low\u003cbr\u003epressure operation.\u003cbr\u003e3. Rebuild differential ion and noble ion pumps at reduced cost.\u003cbr\u003eSummary of Galaxytm Specifications\u003cbr\u003eThe new Galaxy ion pump technology uses two titanium cathodes penetrated with spiral\u003cbr\u003epatterns which are axially co-located beneath the anode cells. Noble gas ions, such as argon,\u003cbr\u003estrike the spiral elements at grazing incidence, resulting in sputtering and neutralization. The\u003cbr\u003eneutralized atoms are permanently buried in inactive areas of the pump.\u003c\/p\u003e\n\u003cp\u003eAn image of a Galaxy cathode is shown below.\u003cbr\u003e1. Pumping speed for active gases: The Galaxy pumping speed and capacity for air,\u003cbr\u003ehydrogen and water is the same as for the standard diode (two flat titanium cathodes).\u003cbr\u003e2. Stability for air pumping: The Galaxy pumping speed for air is stable for all pressures\u003cbr\u003eand extended times measured.\u003cbr\u003e3. Pumping speed for argon: The Galaxy pumping speed for argon is ~ 10% of its pumping\u003cbr\u003espeed for air. This represents ~ 65-70% of the pumping speed for argon of the same geometry\u003cbr\u003eDI (Differential Ion), Noble Diode, Starcell or Triode ion pumps. Galaxy operation for argon\u003cbr\u003eis stable for all pressures and times measured, except at argon operating pressures above about\u003cbr\u003e2 X 10-5 Torr.\u003cbr\u003e4. Lifetime: Accelerated and extrapolated lifetime tests with air and argon indicate that the\u003cbr\u003elifetime of the Galaxy elements is in the same range quoted for other ion pump element\u003cbr\u003etechnologies, i.e. 40,000 to 50,000 hours at an operating pressure of 1 X 10-6 torr.\u003cbr\u003eGalaxy elements plus new and rebuilt ion pumps are available from Duniway\u003cbr\u003eStockroom Corp. for:\u003cbr\u003eVarian-style pumps (Part Number: EL-LG-GX)\u003cbr\u003ePE-style pumps (Part Number: NEW-GXY-2000)\u003cbr\u003eStarcell pumps (Part Number: EL-ST-GX)\u003cbr\u003ePlease inquire for other configurations and special applications.\u003cbr\u003eGalaxy cathodes, elements and pumps are covered by US Patent #6004104\u003cbr\u003eGalaxy is a trademark of Duniway Stockroom Corp.\u003cbr\u003eStarcell is a trademark of Varian, Inc.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003eBrand new.\u003c\/p\u003e\n\u003ch2\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDUNIWAY NEW-GXY-2000 New ION Pump Element PE-style pump\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eLRGS\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cspan style=\"color: #0000ff; text-decoration: underline;\"\u003eWarranty\u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e30 Day warranty.
