| 520 | _ | _ | |a Beryllium with varying surface conditions is exposed to fusion relevant transient heat pulses. The TGP-56FW beryllium samples are ground with silicon carbide papers of increasing grit designation from P80 to P320 to simulate the industrial lathe cut surface conditions for the ITER first wall armour tiles. Up to 1000 heat pulses with a pulse duration of 1 ms and an absorbed power density of 800 MW/m² are applied using the electron beam facility JUDITH 1 at room temperature to test the thermal shock performance of the target samples. Surface characterization and metallographic cross sections show that the resulting material damage is similar for all surface conditions. The arithmetic mean roughness is increasing but the crack parameters remain unchanged for all surface conditions in the range of 100 to 1000 pulses. This study suggests that there is no need for additional surface treatments such as grinding of the industrial cut beryllium armour tiles to improve the thermal shock resistance. |
