The Wisconsin Plasma Astrophysics Laboratory

, 2015
The Wisconsin Plasma Astrophysics Laboratory (WiPAL) is a flexible user facility designed to study a range of astrophysically relevant plasma processes as well as novel geometries that mimic astrophysical systems. A multi-cusp magnetic bucket constructed

Model for second harmonic ECRH plasma start-up in stellarators

Nuclear Fusion
Plasma ionisation avalanche under constant electric field is well described by classical theory. It is the standard tokamak start-up method. In this work, we investigate an analogous avalanche process driven by electron cyclotron resonance (ECR). This is

Notes about Noise in Gravitational Wave Antennas Created by Cosmic Rays

, 2005
Thermodynamical fluctuations of temperature in mirrors may produce surface fluctuations not only through thermal expansion in mirror body but also through thermal expansion in mirror coating.

Biocrude production by hydrothermal liquefaction of olive residue [PDF]

, 2016
Hydrothermal liquefaction (HTL) converts biomass into a crude bio-oil by thermally and hydrolytically decomposing the biomacromolecules into smaller compounds.

Hydrodynamic Simulation of Supernova Remnants Including Efficient Particle Acceleration

, 2003
A number of supernova remnants (SNRs) show nonthermal X-rays assumed to be synchrotron emission from shock accelerated TeV electrons. The existence of these TeV electrons strongly suggests that the shocks in SNRs are sources of galactic cosmic rays (CRs).

Thermal to Nonthermal Energy Partition at the Early Rise Phase of Solar Flares

, 2012
In some flares the thermal component appears much earlier than the nonthermal component in X-ray range. Using sensitive microwave observations we revisit this finding made by Battaglia et al. (2009) based on RHESSI data analysis.

Electron cyclotron resonance near the axis of the gas-dynamic trap

, 2012
Propagation of an extraordinary electromagnetic wave in the vicinity of electron cyclotron resonance surface in an open linear trap is studied analytically, taking into account inhomogeneity of the magnetic field in paraxial approximation.

Observation of the Ettingshausen effect in quantum Hall systems

, 2005
Evidence of the Ettingshausen effect in the breakdown regime of the integer quantum Hall effect has been observed in a GaAs/AlGaAs two-dimensional electron system. Resistance of micro Hall bars attached to both edges of a current channel shows remarkable
