Beam Dynamics Studies for a High Current Ion Injector *
Recent ion source developments resulted in the generation of high brilliance, high current beams of protons and light ions. After extraction and transport the beams with large internal space charge forces have to be captured, bunched and preaccelerated for the injection into the following driver part of a new generation of high intensity beam facilities for neutron sources, energy production, t...
متن کاملEstimation of Ion Beam Trajectories for a Slot Aperture Accelerator of Long-Pulse Ion Source in Neutral Beam Injector
A neutral beam injection (NBI) system has been developed and is being tested for an Experimental Advanced Superconducting Tokamak (EAST) device. The NBI system needs to be employed for an auxiliary heating and current drive of EAST plasmas. The first long pulse ion source (LPIS-1) has been installed in the neutral beam test bed (NBTB) system, and the performance is being tested in the NBTB. The...
متن کاملDevelopment Strategy of RF Ion Source for Neutral Beam Injector in Fusion Devices
Large-area RF-driven ion source is being developed at Germany for the heating and current drive of ITER device [1, 2]. Negative hydrogen ion sources are major components of neutral beam injection systems in future large-scale fusion experiments such as ITER and DEMO. RF sources for the production of positive hydrogen ions have been successfully developed at IPP (Max-Planck-Institute for Plasma ...
متن کاملDemonstration of 500 keV beam acceleration on JT-60 negative-ion-based neutral beam injector
Hydrogen negative ion beams of 486 keV, 2.8A and 507 keV, 1A have been successfully produced in the JT-60U negative ion source with multi aperture, multi grid accelerator of three stages. This is the first accomplishment of the H beam acceleration up to 500 keV at high-current of > 1 A. These successful productions of the high-energy beams at high current have been achieved by overcoming a poor...
متن کاملCaesium influence on plasma parameters and source performance during conditioning of the prototype ITER neutral beam injector negative ion source
Systematic Langmuir probe measurements were performed during the caesium (Cs) conditioning of the IPP prototype negative hydrogen ion source. Conditioning consists of slowly injecting caesium into the source in order to increase the extracted negative ion current and minimize the co-extraced electrons. This process usually takes several days. Measurements were taken near the plasma grid where t...
