The low-Z oxygen and carbon were the main plasma impurities in Wendelstein 7-X (W7-X) stellarator last experimental campaign with passively cooled graphite divertor. To tackle this issue boronization (Winter et al 1989 J. Nucl. Mater. 162–4 712–23) was applied, which has led to one of achievements campaign: operation at high core densities more than 1020 m−3 hydrogen fueled plasmas due reduced radiation-induced density limit.
We present a novel method for optimizing surface modulation structures of solid targets to enhance ion beam yield via the target normal sheath acceleration mechanism. For initially set conical target, we used random walk sampling algorithm optimize microstructure on surface. With only 36 simulations, achieved optimized structure, significantly improving temperature and hot electrons, forming more robust longitudinal electric field. Two-dimensional particle-in-cell simulations demonstrated...
A group of edge diagnostics and modelling has been developed for investigation synergy between 3D physics plasma-wall interactions on Wendelstein 7-X (W7-X). Two endoscopes have designed visible ultraviolet spectroscopy tomography the plasma edge, along with infrared thermography divertor tiles. 2D profiles impurities (e.g. helium, carbon) will be measured by two viewing island region in a spatial resolution <2 mm. multipurpose manipulator, which is used as carrier either probe head...
Laser-driven high-quality ion beams hold immense potential for applications in diverse fields such as tumor therapy, fast ignition, and so on. However, current experimental are often constrained by either a large energy spread or relatively low energy. In this paper, we proposed novel scheme generating quasi-monoenergetic proton irradiating near-critical-density plasmas, which have density gradient with picosecond laser pulse. This approach leverages two key aspects: first, the sustained...
