Dynamics of the IFMIF very high-intensity beam
PAP Nghiem, N Chauvin, M Comunian… - Laser and particle …, 2014 - cambridge.org
For the purpose of material studies for future nuclear fusion reactors, the IFMIF deuteron
beams present a simultaneous combination of unprecedentedly high intensity (2× 125 mA
CW), power (2× 5 MW) and space charge. Special considerations and new concepts have
been developed in order to overcome these challenges. The global strategy for beam
dynamics design of the 40 MeV IFMIF accelerators is presented, stressing on the control of
micro-losses, and the possibility of online fine tuning. Start-to-end simulations without and …
