Implication

Experiment demonstrates that higher preheating temperature affects surface roughness and crack formation in tungsten under pulsed hydrogen plasma exposure.

Key Points

To investigate the influence of preheating on tungsten behavior under pulsed hydrogen plasma exposure.
Examined tungsten plates preheated to various temperatures in a plasma accelerator
Exposed plates to three series of 13 plasma pulses each
Analyzed surface morphology and crack formation using XRD and visual inspection
Surface roughness reached approximately 204 nm after multiple melting cycles
Temperature increases past 773 K showed diminishing returns on crack mitigation
Crack density increased despite preheating, but average crack width remained stable around 0.2–0.3 μm
