Previous studies provide strong evidence for the therapeutic effect of electromagnetic fields (EMFs) on different tissues including cartilage. Diverse exposure parameters applied in scientific reports and the unknown interacting mechanism of EMF with biolo ...
We have developed an ultra-stable low temperature scanning tunneling microscope (LTSTM) for application in atomic scale spectroscopy and atom manipulation experiments. The design is based on the Besocke type microscope allowing the installation of the LTST ...
This Thesis addresses questions related to transport phenomena and the plasma production mechanisms by injection of microwaves in the electron-cyclotron frequency range in the simple magnetised toroidal plasma TORPEX. The second subject is investigated in ...
We present the results of high magnetic field (up to 30 T) and temperature (50 mK-80 K) dependent transport measurements on a 2DEG in GaN/AlGaN heterojunctions. A high mobility (above 60000 cm(2) V-1 s(-1) at 4 K) 2DEG was obtained by MBE growth of disloca ...
During high recycling conditions and divertor detachment in the TCV tokamak, divertor target Langmuir probes never measure electron temperatures much below similar to5 eV. Code simulations using B2-EIRENE of these plasmas indicate that Te approximate to 1 ...
We have fabricated hybrid structures consisting of a metallic thin film and of a microstructured two-dimensional electron system in an InAsheterostructure. The devices are found to exhibit a huge magnetoresistance(MR)effect in magnetic fields ⩽1 T . At low ...
Space charge effects (so-called negative-mass instability) as the reason for electron energy spread developing in the region of the electron drift between the cathode and the cavity of a gyrotron are discussed. The quasioptical gyrotron working at third ha ...
The local properties of the electron energy distribution function are investigated in the electron-cyclotron wave driven toroidal device TORPEX (Fasoli et al 2006 Phys. Plasmas 13 055902). The electron energy distribution function is measured by means of a ...
The electron temperature, pressure and density pro les from an extreme variety of shaped Ohmically heated sawtoothing plasmas in TCV ( Tokamak a Configuration Variable, B-T < 1.5T, R-0 = 0.88 m, a < 0.25 m) are compared to model predictions drawing from tw ...
The parallel velocity distribution function of the weakly relativistic electron beam of a quasi-optical gyrotron has been determined by measuring the Doppler-shifted Electron Cyclotron Emission (ECE) at an angle theta=15 degrees with respect to the externa ...
