This hollow cathode tip is commonly within the discharge cathode (HC) electron source in gridded ion sources. Compare to part number HC500, HC 500, HC-500, H.C. 500 (07HC-001-001). This HCHT500ST tip is a patent-pending long-life version of our standard HCHT500 tip. Both are otherwise identical in form, fit, and function. 1/4 inch diameter cathode tube, 2.054 inch overall length. Orifice diameter Ø0.043" The heater cable has a #10 ring terminal electrical connection at the base of the cathode. Knurled compression tube fitting (common Swagelok double-ferrule type). Intended to be finger-tightened only onto a bulkhead or other male fitting to allow for future removal and replacement. Over-tightening, made more likely when using a wrench, especially when exposed to elevated temperatures during operation, can lead to galling or seizing at the mating surfaces, potentially making removal difficult. Internal patented low work function insert (Pat. No. 10,002,738).
