Generation of rare isotope beams by means of in-flight separation of nuclear fragments and fission products requires complex optical structures usually comprising multiple separator stages. Large apertur magnets providing maximum acceptance, radiation hard and superconducting are used to separate the reference isotope from the bulk of the primary and secondary heayv ion beam. The pre-separator...
The largest hadron accelerator facility in the US is undergoing radical changes and the undertaking of new HEP-driven neutrino research. This talk will discuss the wide-ranging projects and impacts to the accelerator community taking place at FNAL.
Normal conducting proton and ion linacs are vital components for applications in medical treatments, research, and industrial uses. As front-end of high-power proton linacs, they play a critical role in the initial acceleration and conditioning of the proton beam, setting the foundation for successful beam acceleration and high-power performance. INFN-LNL is engaged in different projects for...
HIAF is one of the next generation heavy ion accelerators under construction in China. It is composed of a superconducting ion linear accelerator, a high-energy synchrotron booster, a high-energy radioactive isotope beam line, an experimental storage ring and multiple experimental setups. Characterized by unprecedented intense ion beams from hydrogen through uranium, HIAF can produce a large...
For the China Spallation Neutron Source (CSNS), the rapid cycling synchrotron (RCS) accumulates and accelerates the injection beam to the design energy of 1.6 GeV and then extracts the high energy beam to the target. In this paper, firstly, the beam commissioning of the RCS have been comprehensively studied, including new injection system commissioning, longitudinal dynamics optimization, beam...
High-current compact cyclotrons are fundamentally constrained by strong space-charge forces during axial injection, where low-energy proton beams experience rapid transverse expansion before entering the spiral inflector. We present a novel plasma-assisted neutralization module designed as a compact, drop-in device installed between the final solenoid and the inflector entrance. The concept...
