Numerical analyses and loss tangent measurements for the W7-X ECRH gyrotron diamond output windows

G. Aiello, A. Meier, H. P. Laqua, T. Scherer et autres

The 140 GHz 1 MW gyrotron for the electron cyclotron resonance heating (ECRH) system at the stellarator Wendelstein 7-X (W7-X) is being upgraded to 1.5 MW continuous wave operation to increase the total heating power for achieving operating regimes with high plasma …

On the fracture toughness and structural integrity assessment of MPA CVD diamond in nuclear fusion devices

G. Aiello, P. Estebanez, B. Gorr, A. Meier et autres

Nuclear fusion power plants require electron cyclotron (EC) heating and current drive (H&CD) systems to deploy MW-class, mm-wave radiation, generated by the gyrotrons, to the plasma for heating and control of instabilities. Diamond windows are used as confinement and vacuum barriers on …

Performance of the W7-X ECRH gyrotron diamond output window at 2 MW operation

G. Aiello, Bronislava Gorr, J. Jelonnek, H.P. Laqua et autres

The current electron cyclotron resonance heating (ECRH) system at the stellarator Wendelstein 7-X (W7-X) is in the phase to increase the gyrotron output power from 1 MW to 1.5 MW and, last, up to the target of 2 MW by different steps. …

Overview of JET results

F. Romanelli, M Laxåback, I. Abel, V. Afanesyev et autres

Scientific and technical activities on JET focus on the issues likely to affect the ITER design and operation. Our understanding of the ITER reference mode of operation, the ELMy H-mode, has progressed significantly. The extrapolation of ELM size to ITER has been …
