The effect of microwave frequency and grad B on the ECR heating [PDF]

open access: yes, 1999
In an ECR ion source many parameters are related to the heating of the electrons. The amplitude of the electric field is one of the main factors. In addition to this, many other parameters affect the production of highly charged ions inside the ECR ion ...

On the role of initial and boundary conditions in numerical simulations of accretion flows

open access: yes, 2013
We study the effects of initial and boundary conditions, taking two-dimensional hydrodynamical numerical simulations of hot accretion flow as an example.

Recent Developments for ECR Ion Sources at HIMAC [PDF]

open access: yes, 1999
Two ECR ion sources are installed for the Heavy Ion Medical Accelerator in Chiba (HIMAC) at the National Institute of Radiological Sciences (NIRS). One of them, the NIRS-ECR, is a 10GHz ECR ion source, and is mainly operated to produce C4+ ions for the ...

Cosmic Ray-Dominated AGN Jets and the Formation of X-ray Cavities in Galaxy Clusters

open access: yes, 2010
It is widely accepted that feedback from active galactic nuclei (AGN) plays a key role in the evolution of gas in groups and clusters of galaxies. Unequivocal evidence comes from quasi-spherical X-ray cavities observed near cluster centers having sizes ...
