Abstract

Historically developed for cooling of klystron electronic tubes, metallic hypervapotron prototypes with different width were manufactured for high heat flux plasma facing components (PFC) applications. They were critical heat flux (CHF) tested on the European 200 kW electron beam facility (FE200), the 54 measured values have shown their good performances - up to 25-30 MW per square metre at low axial velocities (2-6 m/s) - interesting for ITER divertor dome and vertical target design. An important conclusion is that CHF decreases when the width increases.
