ITRIP design and the proof of principle test

Abstract To meet the increasing demands for Highly Charged Ion Beams(HCIB) in new and existing heavy ion accelerators, we propose the Ion TRap for high Intensity Pulse beam (ITRIP). ITRIP aims to convert a DC ion beam from an Electron Cyclotron Resonance Ion Source (ECRIS) into a high-intensity, short-pulsed ion beam with suitable compression ratios. The conceptual design of ITRIP, inspired by Electron Beam Ion Sources (EBIS), features a simple trap consisting of an electron gun, a solenoid, and a set of Drift Tubes (DTs). Ions injected from an ECR ion source are trapped radially and axially within the ITRIP. By controlling the potential of the drift tubes, highly charged ions can be accumulated through multiple injections and extracted in pulses of tens of microseconds. To verify the principle of ITRIP, a dedicated ITRIP prototyping platform has been developed. The key issues of ITRIP, including beam injection,beam accumulation and pulsed extraction properties, have been tested and analyzed. Preliminary results and conclusions have been obtained, demonstrating the feasibility and performance of ITRIP as a novel ion trap for generating pulsed high-intensity highly charged ion beams. In this paper, a general overview of the ITRIP concept, its design, and the experimental verification conducted with the platform will be presented.
