| description | The invention relates to turbo molecular pumps enabling high pumping speed. The disclosure suggests using one or more cage-like rotor stages to optimize pumping speed on vacuum systems with low gas flows and low ultimate pressures. This allows for a smaller motor as well as smaller overall form factor and makes it well suited, in particular, for compact mass spectrometers and desk-top mass spectrometers. |
