  abstract = {<p>The erosion behaviour of selective laser melting (SLM) tungsten Capillary Porous Structure (CPS) targets filled with lithium (Li) was investigated in the Quasi-Stationary Plasma Accelerator (QSPA) under transient plasma loading. Plasma pulses (0.25 ms, about 3 MJ/m2) were applied to two CPS targets, one oriented normally and the other inclined relative to the incident plasma stream. High-speed observations of plasma-surface interaction showed that particle release from the surface was strongly governed by the incident energy density. Low-energy exposures (\&lt;1.2 MJ/m2) resulted in only minor particle release, whereas higher loads led to significant ejection with velocities up to 33 m/s. Post-mortem analysis of the CPS target under oblique plasma exposure revealed erosion at the leading edge, pointing to this region as a critical factor in target resilience. In addition, Li- and Sn-filled CPS samples were compared under both normal and inclined irradiation in regimes representative of fusion-relevant transient events.</p>},
