Electrical neuroimaging based on biophysical constraints

This paper proposes and implements biophysical constraints to select a unique solution to the bioelectromagnetic inverse problem. It first shows that the brain's electric fields and potentials are predominantly due to ohmic currents. This serves to reformu ...

Control of electron internal transport barriers in TCV

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Laurie Porte, Alexander Karpushov, Roland Behn, Andrea Scarabosio, Andrei Martynov, Petri Nikkola

Current profile tailoring has been performed by application of electron cyclotron heating (ECH) and electron cyclotron current drive, leading to improved energy confinement in the plasma core of the TCV tokamak. The improved confinement is characterized by ...

Etude de la microstructuration du verre par étincelage assisté par attaque chimique

Valia Fascio

We are surrounded by glass! This material has been greatly used for thousand years. More than 2000 years ago in ancient Egypt glass was used to manufacture bottles of perfume. So its first uses were primarily related to decoration and jewellery. The resear ...

Deuterium to helium plasma-wall change-over experiments in the JET MkII-gas box divertor

Richard Pitts

The deuterium and helium dynamics in the plasma and subdivertor regions of JET are compared during a sequence of similar ohmic and ICRH pulses where 100% He gas is injected into the JET vacuum vessel, whose graphite walls were previously saturated with deu ...

Pressure drop and helium inlet in ITER CS1 conductor

Pierluigi Bruzzone

A number of pressure drop measurements have been carried out at CRPP on a section of ITER cable-in-conduit conductor, using pressurized water at room temperature. The longitudinal friction factor is deduced for the strand bundle area and the central hole. ...

On locating the poloidal field coils for tokamak vertical position control

Yves Martin, Jean-Marc Moret, Jonathan Bryan Lister

The TCV tokamak has 16 poloidal field coils for plasma shaping, distributed around the vacuum vessel. Experiments are described that determine the relative merits of different coil positions for controlling the unstable vertical movement of elongated plasm ...

Electron-Cyclotron Resonance Heating on the Tca Tokamak

Timothy Goodman, Minh Quang Tran, Antoine Pochelon, Roland Behn

Electron cyclotron resonance heating (ECRH) experiments at 39 GHz with power levels similar to those of Ohmic heating have been conducted in the TCA tokamak, in either the X-mode or the O-mode. ECRH was observed to be more efficiently absorbed in low densi ...

Preparation and characterization of titanium/lead(IV) oxide-type electrodes

Christos Comninellis

The coating of PbO2 [1309-60-0] on Ti was carried out after activation of the Ti in boiling HCl 20% and after predeposition with an intermediate protective Au layer. The stability measurements of this electrode showed that the rate of decompn. of PbO2 in H ...
