Abstract:
An exhaust apparatus and a high vacuum pumping unit including such high vacuum device and an auxiliary vacuum pump are disclosed, wherein a high vacuum is achieved in a vacuum vessel such that the gas molecules within the vacuum vessel are ionized and accelerated to be exhausted and, further, in the high vacuum pumping unit, those gas molecules diffused back or desorbed from the vacuum pump are ionized and accelerated to be returned to the vacuum pump.

Abstract:
An ultra-high vacuum (UHV) system includes a UHV cell and an ion pump to maintain the UHV in the UHV cell. The ion pump has a GCC (glass, ceramic, or crystalline) housing. An interior wall of the ion-pump housing serves as an anode or bears a coating that serves as an anode. At least one cathode is disposed with respect to the housing so that it can cooperate with the anode to form an electric field for establishing a Penning trap. The GCC housing defines a flow channel that extends radially through the anode so that a molecule can flow directly into the most ionizing region of a Penning trap.
Abstract:
A vacuum pump wherein a a traveling magnetic wave coupled to ionized gas particles propels the particles from the inlet of the pump to the outlet thereof. Gas within the coupling region of the traveling wave is kept ionized by a high temperature electron emitting structure which directs electrons through said region. A roughing and backing pump is provided to bring the pressure in the system down to about 20 mm of mercury at which time the traveling-wave pump takes over.
