摘要

A test facility for high heat and particle loads relevant to a fusion divertor has been developed using an applied-field magnetoplasmadynamic (AF-MPD) thruster. The AF-MPD thruster can provide high heat and particle fluxes to a target at a relatively low pressure with a relatively strong magnetic field. Several diagnostics for heat and particle fluxes such as a calorimeter and Langmuir probe were utilized to confirm that a heat flux of 4.0 MW m(-2) and particle flux of 4.2 x 10(22) m(-2) s(-1) were achieved using a 0.17 T permanent magnet. The electron temperature and electron density were estimated to be 4 eV and 10(13) cm(3), respectively, using optical emission spectroscopy based on the collisional-radiative model.
