Journal ArticleDOI
Interpretation of Be migration studies at JET and validation of an integrated numerical model for plasma impurity transport and wall composition dynamics
TL;DR: In this article, the authors present a model that combines parameterized DIVIMP calculations and a simplified sputtering model to simulate the time evolution of first wall material migration in a fusion experiment.
Proceedings ArticleDOI
Hybrid Couplers On The JET ICRF System: Commissioning And First Results on ELMs
M.-L. Mayoral,I. Monakhov,T. Walden,V. Bobkov,T. R. Blackman,M. E. Graham,J. Mailloux,J.-M. Noterdaeme,M. P. S. Nightingale,J. Ongena,Jet-Efda Contributors +10 more
TL;DR: In this paper, a hybrid 3 dB couplers were installed between the A2 ICRF antennas A and B to monitor the forward and reflected voltage amplitudes with a time resolution up to 4 μs.
Journal ArticleDOI
Atomic modeling and instrumentation for measurement and analysis of emission in preparation for the ITER-like wall in JET
M. G. O'Mullane,Hugh Summers,A. D. Whiteford,A. G. Meigs,K. D. Lawson,K.-D. Zastrow,Robin Barnsley,I. H. Coffey,Jet-Efda Contributors +8 more
TL;DR: In this article, a suite of spectroscopic diagnostics in the visible, extreme ultraviolet, vacuum ultraviolet, and x-ray spectral regions suitable for these tasks is described. But the authors do not specify the spectrum characteristics of the upgraded JET.
Journal ArticleDOI
Demonstration of real-time control of impurity seeding plus outboard strike-point sweeping in JET ELMy H-mode plasmas
G. P. Maddison,C. Giroud,G. K. McCormick,B. Alper,G. Arnoux,P. C. da Silva Aresta Belo,M. N. A. Beurskens,A. Boboc,A. Brett,S. Brezinsek,I. H. Coffey,Stéphane Devaux,P. Devynck,T. Eich,R. C. Felton,W. Fundamenski,J. Harling,A. Huber,S. Jachmich,E. Joffrin,P. J. Lomas,P. Monier-Garbet,P.D. Morgan,M.F. Stamp,G. Telesca,H. Thomsen,I. Voitsekhovitch,Jet-Efda Contributors +27 more
TL;DR: In this article, strike-point sweeping and real-time-controlled impurity seeding are combined in high-triangularity type I H-mode plasmas, using a VUV spectroscopic signal for feedback control of nitrogen injection, and similar strong mitigation of divertor heat load between ELMs was achieved in swept RTC cases for less than half the integrated nitrogen input and correspondingly less adverse effect upon other properties.
Journal ArticleDOI
New developments at JET in diagnostics, real-time control, data acquisition and information retrieval with potential application to ITER
J. Vega,A. Murari,B. Carvalho,G. de Arcas,R. Felton,M. Riva,Mariano Ruiz,J. Svensson,Jet-Efda Contributors +8 more
TL;DR: To reduce the amount of data, a prototype of real-time adaptive data acquisition techniques is being implemented, to adjust the acquisition frequency to the time resolution of the phenomena to be analysed in the plasma.
