CVD diamond microwave optics enabling high power RF generators

Our CVD diamond microwave optics play a crucial role in the development of sustainable energy systems such as nuclear fusion

CVD diamond’s properties make it a unique solution enabling the construction of two megawatt gyrotrons used to heat plasma in the fusion reactor;

      • Low absorption in the radio frequency range
      • High mechanical strength
      • High thermal conductivity

The beam line microwave windows facilitate low loss transportation of high energy radiation from the source (gyrotron) to the target (plasma).

Our radio-frequency (RF) optics solutions

Element Six synthetic diamond is used in RF optics including;

      • Gyrotron windows: exit windows for high power gyrotrons both mounted and un-mounted
      • ECRH beam line windows
