英文摘要

The Electron Cyclotron Resonance Ion Plasma ACcelerator (ECRIPAC) is an original accelerator concept proposed in the nineties for the generation of highly energetic pulsed ion beams, suitable for a wide array of applications. The initial studies on the subject were characterized by an important calculation mistake, leading to an incomplete and erroneous literature on the topic. Nevertheless, the simple and well mastered techniques involved in the system (radio frequency and magnetic field), together with the device compactness, are strong motivations for further studies on ECRIPAC. The working principle and physical theory behind the ECRIPAC accelerator concept are thoroughly reviewed in this paper, incorporating significant corrections to the existing literature on the subject, making this work a suitable reference for future studies. A detailed theoretical investigation of the stability condition for the ion acceleration is presented, highlighting more stringent limitations than previously anticipated. Next, the impact of several physical parameters on the accelerator design is analyzed. This study led to the design of a compact demonstrator device able to accelerate He2+ ions up to 9.5 MeV per nucleon inside a 1.8 m long accelerating cavity. Finally, the results of a Monte-Carlo simulation, developed to model the electron dynamics inside the system, are used to validate the theoretical framework of ECRIPAC.
