The SCENIC code package has been developed to integrate self-consistently an anisotropic pressure magnetohydrodynamic equilibrium state with power absorption from ion cyclotron resonance heating and with a guiding center particle distribution function for the energetic particles generated in three-dimensional geometry. The main novelty constitutes the inclusion of the background equilibrium sta...

The coupled RFQ and SFRFQ cavity has been manufactured and tested recently. According to the beam dynamic design, the input He beam within 120° phase width is designed for the cavity to achieve over 98% transmission efficiency. An energy modulated electron cyclotron resonance (ECR) ion source was proposed and simulated. To achieve the 1% energy modulation on the 30keV direct current (DC) beam, ...

Future high intensity ion accelerators, including the Spallation Neutron Source (SNS), the European Spallation Source (ESS), the Superconducting Proton Linac (SPL) etc, will require high current and high duty factor sources for protons and negative hydrogen ions. In order to achieve these goals, a comparison of the Electron Cyclotron Resonance, radio-frequency and Penning ion sources, among oth...

Abstract The effect of electron cyclotron resonance heating (ECRH) on fishbone instability is studied based the generalized energy principle. Off-axis ECRH plays a stabilizing role in instability, while on-axis does not distinctly change growth rate. frequency increases (decreases) for off-axis (on-axis) ECRH. greatest when power deposited near rational surface. More concentrated deposition has...

This paper discusses ion sources used in high-dutyfactor proton and H Linacs as well as in accelerators utilizing multi-charged heavy ions, mostly for nuclear physics applications. The included types are Electron Cyclotron Resonance (ECR) sources as well as filament and rf driven multicusp sources. The paper does not strive to attain encyclopedic character but rather to highlight major lines of...
