Abstract (en)
[origin: WO2020079428A1] A set of pumps, method and system for providing a high vacuum within a radioactive environment is disclosed. The set of pumps comprise: a primary pump configured for operation outside of the radioactive environment and configured to connect to a chamber within the radioactive environment via a conduit, the primary pump being configured to evacuate the chamber to a first pressure; a radiation resistant intermediate pump configured for operation within the radioactive environment and configured to evacuate the chamber from the first pressure to a second lower pressure; and a radiation resistant high vacuum pump configured for operation within the radioactive environment and configured to evacuate the chamber from the second lower pressure to a third operational vacuum pressure.
