On The Non Thermal Emission and Acceleration of Electrons in Coma and Other Clusters of Galaxies
, 2001 Some clusters of galaxies in addition to thermal bremsstrahlung (TB), emit diffuse radiation from the intercluster medium (ICM) at radio, EUV and hard x-ray (HXR) ranges.

Impact of two-close-frequency heating on ECR ion source plasma radio emission and stability
Plasma Sources Science & Technology, 2019 Experiments have recently demonstrated that kinetic instabilities occurring in magnetoplasma are huge limiting factors to the flux of highly charged ion beams extracted from ECR ion sources. Recently, it has been shown that the two-frequency-heating (TFH)

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.Over the last 150 years, most large, easily accessible lakes and tarns in Aotearoa (New Zealand) have experienced trout introductions or incursions, leaving few salmonid‐free reference lakes. Using database information and field surveys, we characterized lake, pond/tarn, and wetland systems found throughout Aotearoa that support populations of kōaro ...

Thermal and non-thermal traces of AGN feedback: results from cosmological AMR simulations
, 2012 We investigate the observable effects of feedback from Active Galactic Nuclei (AGN) on non-thermal components of the intracluster medium (ICM). We have modelled feedback from AGN in cosmological simulations with the adaptive mesh refinement code ENZO ...

Concept for controlled transverse emittance transfer within a linac ion beam [PDF]
, 2011 For injection of beams into circular machines with different horizontal and vertical emittance acceptance, the injection efficiency can be increased if these beams are flat, i.e. if they feature unequal transverse emittances.

European Journal of Education, Volume 61, Issue 2, June 2026.ABSTRACT This study explores how international and interdisciplinary research collaboration is experienced and sustained in practice, with particular attention to the roles of early‐career researchers (ECRs). Drawing on a collaborative autoethnographic approach, we analyse four collaboratively constructed narrative vignettes from a three‐year UK–China ...

Millimeter-wave, megawatt gyrotron development for ECR (electron cyclotron resonance) heating applications [PDF]
, 1990 To address the electron cyclotron heating requirements of planned fusion experiments such as the International Thermonuclear Experimental Reactor (ITER) and the Compact Ignition Tokamak (CIT), Varian is developing gyrotrons at frequencies ranging from 100--300 GHz with output power capabilities up to 1 MW CW.

Plasma heating due to X-B mode conversion in a cylindrical ECR plasma system
, 2004 Extra Ordinary (X) mode conversion to Bernstein wave near Upper Hybrid Resonance (UHR) layer plays an important role in plasma heating through cyclotron resonance.

Electron Bernstein waves in spherical tokamak plasmas with "magnetic wells"
, 2004 In addition to traditional regimes with monotonously increasing magnetic field, regimes with "magnetic wells" also occur in spherical tokamaks (STs). The magnetic field profile inversion modifies significantly the whole picture of the wave propagation ...
