Recently, a new H- source and test stand was developed at CIAE. The design of this is based on the experience our previous 10-15 mA H(-) ion TRIUMF. Major efforts include study virtual filter magnetic field, confining filament shape location, vacuum improvement extracting area, extraction optics, control interlock system power supplies. More than 15 H-beam obtained for 36 h with stability +/-0.5%. normalized emittance 0.48pi mm mrad (4 rms emittance) were measured approximately 8 dc beam....
A 100 MeV H- compact cyclotron is under construction at China Institute of Atomic Energy (CYCIAE-100). The proton beams 75 MeV-100 an intensity 200 μA will be extracted in dual opposite directions by charge exchange stripping devices. crossing point the switching magnet center fixed inside yoke and points for various extraction energies are calculated code CYCTRS. With GOBLIN, we can calculate transfer matrix including dispersion effects from to switch magnet. beam distribution just after...
The construction of a 100-MeV high-intensity cyclotron, from which proton beam will be extracted through stripping to several lines for different users, has been completed at China Institute Atomic Energy. Given that it is the H-ions are accelerated in machine, peak field only 1.35 T. To simplify fabrication, pole adopts straight sector instead spiral one. Meanwhile, vertical focusing should sufficiently high obtain high-current beam. All these demands make particularly difficult design and...
An analytical model based on the negative mass instability is introduced in this paper to explain formation of breakup a coasting beam into small clusters isochronous machines such as case observed by Pozdeyev and Rodriguez ring. Solving Poisson’s equation both charge vacuum regions with longitudinal density perturbation, coherent radial space force which decreases transition gamma obtained. It found that modified depends wave number distribution, intensity, size. By combining caused...
As a part of the Upgrade Project Beijing Tandem Accelerator Laboratory, 100 MeV compact cyclotron was designed for generation high intensity proton beams. Due to limit acceptance by central region, new H− cusp source developed at China Institute Atomic Energy. The design this is based on TRIUMF’s experience. More than 10 mA beam with measured emittance 0.65 π mm mrad are obtained voltage 28 kV from an extraction hole 11 in diameter. In article, structure source, magnetic field configuration...
For the applications of proton therapy and irradiation, based on R&D starting from 2009, a construction project 230-MeV superconducting cyclotron (CYCIAE-230) was launched at China Institute Atomic Energy in January 2015. A compact main magnet design with warm iron yokes coil system is adopted to reduce size and, consequently, lower operation cost cyclotron. In this paper, physics design, along mechanical magnet, including structure described detail; then, progress <italic...
