Near-field Ion Current Density Measurements
Faraday probe measurements were taken in the near-field plume of a 6-kW Hall thruster to reduce the negative effects of facility-induced charge-exchange collisions. The results from these measurements were analyzed using a non-standard definition of the current density integration bounds that produced self-consistent beam current and beam divergence values. The measurements indicated a beam div...
متن کاملMixed moderate thermophilic bioleaching of Cu, Mo and Re from molybdenite concentrate: effects of silver ion, medium and energy sources
This study evaluates the effects of different additives such as silver ion, medium and energy sources on the efficiency of mixed moderate thermophilic bioleaching approach to extract Cu, Mo and Re from molybdenite concentrate containing 0.98% Cu, 1.56% Fe, 53.84% Mo, and 0.055% Re. Molybdenite was the major phase of Mo-bearing mineral and chalcopyrite, covellite and pyrite were distinguished as...
متن کاملEmittance Measurements and Operation Optimization for Ecr Ion Sources
Electron Cyclotron Resonance (ECR) ion sources supply a broad range of ions for post acceleration in cyclotrons. Here, an effort to improve the beam transfer from RIKEN’s 18 GHz superconducting ECR ion source (SC ECRIS) to the Low Energy Beam Transfer (LEBT) line and an optimization of the performance of the ion source is presented. Simulation studies have shown that less than 20% of the beam i...
متن کاملReview of Negative Hydrogen Ion Sources High Brightness/high Current
Due to the development of reliable H ion sources, charge-exchange injection into circular accelerators has become routine. This paper reviews recent developments in negative hydrogen ion sources. The underlying physics, operating parameters and beam characteristics of selected sources will be described and compared. Figure 1: History of duoplasmatron and surface source development.
