Abstract (en)

[origin: EP0610666A1] The present invention refers to a turbomolecular pump (turbo-pump) (1000) having a cold trap panel (414) wherein the trap panel contains an annular panel (416), a disk-shaped panel (420) and a supporting frame (418) that connects the annular panel (416) to the disk-shaped panel (420) such that these two panels are coaxially positioned relative to one another. The trap panel (414) is positioned within an inlet (410) to the turbo-pump (1000) and coaxially aligned with a main axis of an impeller shaft (404) thereof. Additionally, a heater (1002) is located proximate said trap panel (414) such that, when energized, the heater (1002) relatively quickly vaporizes any molecules adsorbed by the trap panel (414). <IMAGE>
