In a specific voxel-based analysis, each voxel is assigned a single 3D fiber orientation vector.

This makes it difficult to determine an optimal design.

A pragmatic approach is advocated considering a pulsed tokamak based on mature technologies and reliable regimes of operation, extrapolated as far as possible from the ITER experience.

Due to its high demand in electrical energy the H&CD efficiency optimization is an important goal in the DEMO development.The H&CD power for DEMO, based on physics scenarios for the different plasma phases, is needed for plasma initiation phases (incl.

The current baseline concept is a tokamak reactor with net electrical output power of Pel ∼ 500 MW and plasma pulse duration of tpulse ∼2 h.

Mössbauereffekt-Untersuchungen der magnetischen Hyperfeinwechselwirkungen an Eu-151 in Europiummonochalkogeniden bei hohen Drucken und hohen Magnetfeldern [Juel-1817] Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 1817, 75 p. (1982) In this work the M6Bbauer effect on the 21.6 keV $\gamma$-transition of $^{151}$Eu has been used to investigate the pressure dependence of the magnetic hyperfine interaction in the ferromagnetically saturated phase of EuS, EuSe and EuTe applying simultaneously high pressure up to 20 kbar and high external magnetic fields of about 12 T. Moreover, we have studied the effect of pressure on the core polarization field B$_{c}$ of the Eu$^{2+}$-Ion in the magnetic dilution system $Eu_{x}Sr_{1-x}S$.

(1984) This report describes a measuring apparatus controlled by the PDP-11/40 process computer and used for measuring the transient magnetic fields in the Jülich TEXTOR tokamak machine. The measuring results were moreover used for numerical off-/ine computation of the amplitudes and time constants of the exponentially decaying fractions of the magnetic field which are caused by eddy currents in the meta/ parts of the machine.
