NON EVAPORABLE GETTER PUMPING FOR JET ICRF ANTENNAE
The JET ICRF A-1 Antenna Vacuum Transmission Lines will be pumped with individual non-evaporable getter pumps. The pump is a cartridge type in an all-welded body which is heated externally to give activating, operating and regenerating temperatures. The pumped Hydrogen is periodically regenerated back into the torus. This will be particularly advantageous during the tritium phase of operation. The pump is simple and gives a high reliability. It is tolerant of conditions close to the torus and can be sited within the volume reserved for installation of the RF transmission lines. The all- welded system simplifies remote handling. Tests on prototype pumps are being conducted to establish operational data and confirm contamination, saturation and embrittlement levels. A getter pump has been installed on one of the existing antenna systems on JET, no difficulties have been experienced in operating this antenna.
