          ■ High-voltage feedthroughs are Thermionics, Perkin-Elmer (Alberox type), Varian style or 
              standard BNC type connectors
          ■ All pumps are tested for vacuum integrity and excessive electrical leakage current
          Custom Design ion Pumps

          To meet your special application requirements, any of our pumps can be built in a custom configuration. All of the pumps are manufactured in the USA. Prefab pump subassemblies are kept in stock. We can modify them, process, and ship your custom pump in two weeks or less.

          In-Line, Tube Type Ion Pump, Straight Through, 150 l/sec, Line of Sight Ion Pump
          This unusual ion pump illustrates Thermionics’ ability to meet special needs. In this case, the need was for pumping on either side of the magnetic deflection sector of an ultra-high vacuum mass spectrometer. Either of the large ports or the small ports can be attached to the system, providing good conductance and a savings in the cost of fittings. This pump allows line-of-sight conductance for X-ray beams, laser beams, and highenergy particle beams. Because of the small magnetic fringing field, it is not recommended for low-energy particle beams.

          Height      163/4”            Small flange    6” O.D., 2.5” I.D.
          Diode Pumps

          20 l/sec Ion Pump

          We manufacture three configurations of diode pumps: standard, hydrogen and noble (D-I) types. For theory of operation, selection criteria, pumping speed curves and alternative configuration options (e.g., double-ended pumps) see Thermionics main catalog or contact a Thermionics sales engineer.

          Triode Pumps
          Triode pumps have the highest speeds for pumping noble gases. The cathode design consists of multiple strips of titanium held at a negative high voltage. For theory of operation, selection criteria, pumping speed curves and alternative configurations (e.g. double-ended pumps) see Thermionics’ main catalog or contact a Thermionics sales engineer.

          Combo-Vac Pumps

          Thermionics Combo-Vac pumps combine a noble diode (D-I) ion pump, a titanium sublimation pump (TSP), and a cryo-shroud, in a single package. This combination provides ideal UHV pumping characteristics for the processing of high power vacuum tubes, x-ray sources, etc. Prices for Combo-Vac pumps include power supplies and cables for the ion pump and TSP.
