Simulating beam ion charge exchange in MAST-U

MAST Team, EUROfusion WPTE team

Research output: Contribution to conferencePaperScientific


Atomic processes were implemented in the orbit-following code ASCOT for simulating fast-ion charge exchange (CX) in magnetically confined fusion plasmas. The model was verified by reaction mean free path estimation and agrees with TRANSP to within 20% on CX losses. ASCOT predicts that 22% of beam power is lost due to CX in a MAST-U target scenario. While plasma heating and current drive are decreased towards the edge, CX is predicted to increase current drive closer to the core. Peak wall power loads of 60-90 kWm-2are estimated on the central poloidal field coils and the vacuum vessel between them.
