When exposed to ionising radiation, living tissue can potentially suffer somatic and genetic damage - effects depending mainly on the radiation dose or energy absorbed, the type of radiation, and the type and mass of cells affected. It is well known that l ...
The transport of particles in magnetically confined plasmas is of great importance for the development of fusion energy. It will determine techniques for fuelling, for controlling impurity concentrations and for the removal of the alpha particles produced ...
In the Large Helical Device (LHD), the highest operational averaged beta value has been expanded from 3.2% to 4% in the last 2 years by increasing the heating capability and exploring a new magnetic configuration with a high aspect ratio. Although the magn ...
Recent scientific and technical progress on JET is summarized. The scientific programme on JET over the last 2 years has benefited significantly from various technological developments: advanced real time tools, enhanced heating systems and several upgrade ...
The modification of the stability and the behaviour of core MHD with local electron cyclotron current drive (ECCD) is presented. Starting from the innermost resonant surface, the q = 1 surface, the stability and hence the sawtooth period and the size of sa ...
Alzheimer's disease (AD) is a progressive neurodegenerative disorder with clinical manifestations appearing in old age, however, the initial stages of this disease may begin early in life. AD is characterized by the presence of excessive deposits of aggreg ...

Firsts results on particle detection using a novel silicon pixel detector are presented. The sensor consists of an array of 48 square pixels with 380 μm pitch based on a n-i-p hydrogenated amorphous silicon (a-Si:H) film deposited on top of a VLSI chip. Th ...
In a tokamak fusion reactor the energetic alpha particles will transiently stabilize the magnetohydrodynamic activity causing sawtooth oscillations. The crash events terminating long sawtooth free periods can provide seed islands for neoclassical tearing m ...
The development of reliable H-modes on MAST, together with advances in heating power and a range of high spatial resolution diagnostics, has provided a platform to enable MAST to address some of the most important issues of tokamak stability. In particular ...
The Collider Detector at Fermilab (CDF) experiment's Silicon Vertex Trigger (SVT) is a system of 150 custom 9U VME boards that reconstructs axial tracks in the CDF silicon strip detector in a 15 μs pipeline. SVT's 35 μm impact parameter resolution enables ...
