Fast ions generated by fusion reactions or auxiliary heating system play a quite essential role in magnetic confinement fusion reactor. The experiments on ASDEX-U and DIII-D have shown that low-frequency MHD activities like TM or NTM will induce the fast ion losses[1][2]. Theoretical and simulation analyses indicate two distinct mechanisms for low-frequency MHD-induced fast-ion losses (FIL)....
A new self-consistent 1D scrape-off layer model is recently developed in BOUT++ framework, named SD1D, which includes transport equations of various particle species (e.g. main plasma, neutrals and impurities) and couples collisional and radiative reactions by using open databases like ADAS and AMJUEL. In this work, SD1D is used to model divertor detachment experiments on two tokamak devices,...
Accurate measurement of charged fusion products in magnetically confined plasmas faces significant challenges due to plasma radiation exposure, electromagnetic interference, thermal loads, and background bombardment by electrons/ions, which generate substantial noise while yielding sparse signals. To address these issues, advanced solutions are required beyond conventional detector design and...
