Comparative studies of various types of transmission lines in the frequency range 70 GHz 1 THz for ITER ECE diagnostic [PDF]

EPJ Web of Conferences, 2019
In ITER, an Electron Cyclotron Emission (ECE) diagnostic is planned to measure the electron temperature by measuring the cyclotron radiation in the frequency range of 70-1000 GHz.

Calculating the 3D magnetic field of ITER for European TBM studies

, 2015
The magnetic perturbation due to the ferromagnetic test blanket modules (TBMs) may deteriorate fast ion confinement in ITER. This effect must be quantified by numerical studies in 3D.

Test Results from the PF Conductor Insert Coil and Implications for the ITER PF System [PDF]

, 2009
In this paper we report the main test results obtained on the Poloidal Field Conductor Insert coil (PFI) for the International Thermonuclear Experimental Reactor (ITER), built jointly by the EU and RF ITER parties, recently installed and tested in the CS

Iterating iterated substitution

Theoretical Computer Science, 1977
AbstractBy iterating iterated substitution not all regular languages can be copied. Hence the smallest full hyper (1)-AFL is properly contained in ETOL, the smallest full hyper-AFL. The number of iterations of iterated substitution gives rise to a proper hierarchy. Consequently the smallest full hyper (1)-AFL is not a full principal AFL.

On the Method of Harmonic Balance for Lumped‐Element Transformer Models

International Journal of Circuit Theory and Applications, EarlyView.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

Effect of impurities on the transition between minority ion and mode conversion ICRH heating in (3He)-H tokamak plasmas [PDF]

, 2013
Hydrogen majority plasmas will be used in the initial non-activated phase of ITER operation. Optimizing ion cyclotron resonance heating (ICRH) in such scenarios will help in achieving H-mode in these plasmas.

ITER monoblock performance under lifetime loading conditions in Magnum-PSI

Physica Scripta, 2020
The ITER divertor will be exposed to extremely high plasma fluences over its lifetime, and it is known that plasma exposure can lead to a variety of particle-induced surface-morphology and microstructure changes in tungsten.

Iterated discriminants

Journal of Symbolic Computation, 2009
In this paper the authors prove that the discriminant of the discriminant of a multivariate polynomial has the same irreducible factors of the product of seven polynomials. These seven polynomials are obtained as the GCD of the generators of an elimination ideal. This result is similar to the one by \textit{L. Busé} and \textit{B.

The EU's Strategy for Sustainability: A Landmark Turn With the European Green Deal?

European Policy Analysis, EarlyView.
ABSTRACT While the European Green Deal (EGD) has been widely recognized as a milestone in the EU's sustainability strategy, scholars disagree on the nature of the policy change it represents. Critics highlight its limited social and environmental ambitions, despite its portrayal as a “man on the moon” moment.

Iterated and generalized iterated integrals

Journal of Algebra and Its Applications
For a differential field [Formula: see text] having an algebraically closed field of constants, we analyze the structure of Picard–Vessiot extensions of [Formula: see text] whose differential Galois groups are unipotent algebraic groups and apply these results to study stability problems in integration in finite terms and the inverse problem in ...
