Abstract

The performance limit for induction brazed beryllium tiles of 2 mm thickness has been measured previously as 17 MW/m2. The aim of this research was to demonstrate that the tiles could sustain over 1000 cycles at a power density of 75 % of this limit. After being induction brazed onto an actively cooled CuCrZr vapotron, the tiles were exposed to approximately 1000 cycles at essentially fixed beam settings. During the cycling all tiles maintained the cooling without deterioration. In an area of 200 x 54 mm2 there was only one 6 x 6 mm2 area well outside the beam centre which showed increased temperatures.
