Let’s go Gyrotrons!   

Kick-off meeting for the gyrotron manufacturing contract with THALES


On 8 December, an IRFM delegation visited the THALES site in Vélizy (close to Paris) in order to attend the kick-off meeting for the supply of three gyrotrons of 105 GHz/1MW with long pulse capability (up to 1000 seconds). Gyrotrons are very high frequency wave generating systems. These new gyrotrons will power an ECRH (Electron Cyclotron Resonance Heating) antenna to heat the WEST plasma. Thanks to this antenna, the heating capabilities of the plasma core will be increased while controlling impurities.

THALES introduced its team and displayed the design of the gyrotrons as well as how they will be produced and tested. During the visit of THALES premises, IRFM team could also see how the system will be built and brazed.

The WEST gyrotron is named « TH1511 ». The first one should be delivered at Cadarache by February 2023.
