W.J. Urbanus,R.W.B. Best,W.A. Bongers,A.M. van Ingen,P. Manintveld,A.B. Sterk,A.G.A. Verhoeven,M.J. van der Wiel,M. Caplan,V. L. Bratman,G. G. Denisov,A.A. Varfolomeev,A.S. Khlebnikov +12 more
TL;DR: In this article, the main components of the free-electron maser, the electron beam line, the undulator and the millimetre-wave system are described, which are optimized with the help of a fully 3D, particle-pusher, FEM simulation code.
Journal ArticleDOI
Comparison of the performance of different options for the ITER ECRH Upper Launcher
TL;DR: In this paper, the performance of different options for the ITER ECRH upper launcher is analyzed in terms of NTM stabilisation efficiency, which is the main task for this system.
Journal ArticleDOI
High-power electrostatic free-electron maser as a future source for fusion plasma heating: experiments in the short-pulse regime.
W.H. Urbanus,W.A. Bongers,C.A.J. van der Geer,P. Manintveld,Jeroen Plomp,J. Pluygers,A.J. Poelman,P.H.M. Smeets,A.G.A. Verhoeven,V. L. Bratman,G. G. Denisov,Andrey V. Savilov,M Y Shmelyov,M. Caplan,A.A. Varfolomeev,S V Tolmachev,S.N. Ivanchenkov +16 more
TL;DR: A high-power, frequency-tunable electrostatic free-electron maser, being developed at the FOM Institute for Plasma Physics "Rijnhuizen," shows lasing at various frequencies and the main issues, such as the possibility of high- power, single-mode operation and frequency tuning, have been confirmed.
Journal ArticleDOI

TL;DR: In this article, the authors investigated the modulation capabilities of the 140 GHz/1 MW gyrotron for long-pulse operation with deep modulation in phase with the tearing mode.
Journal ArticleDOI
First mm-wave generation in the FOM free electron maser
A.G.A. Verhoeven,W.A. Bongers,V. L. Bratman,M. Caplan,G. G. Denisov,C.A.J. van der Geer,G.P. Manintveld,A.J. Poelman,Jeroen Plomp,Andrey V. Savilov,P.H.M. Smeets,A.B. Sterk,W.H. Urbanus +12 more
TL;DR: The Dutch Free Electron Maser (FEM) as discussed by the authors was built as a pilot experiment for a mm-wave source for applications on future fusion research devices such as ITER, the International Tokamak Experimental Reactor.
