Non-evaporable getter pump operations in the TCV tokamak

Highlights: • A non-evaporable getter pump using the ZAO NEG alloy was installed on TCV and tested. • The pump performance was determined from in-situ pumping speed measurements. • The results of the tests indicate that current getter pump technologies are well suited to tokamak operations. A non-evaporable getter pump using the ZAO alloy was installed on TCV and operated during the 2019 experimental campaign. The pump performance, determined from in-situ pumping speed measurements, indicates that current getter pump technologies are well suited to tokamak operations with high power exhaust plasmas, and provide an interesting alternative for applications in fusion experiments.
