Abstract
We have tested the thermal performance of a water-cooled diamond double-cry stal monochromator under twice the typical undulator thermal load at the Ad vanced Photon Source (APS). With two 3.3-cm-period undulators installed in series in the APS sector 1 straight section, the maximum power and normal p ower density incident on the first crystal were 705 W and 312 W/mm(2), resp ectively. The maximum power and surface power density absorbed by the coole d diamond were 140 W and 16.7 W/mm(2), respectively. The monochromator perf ormed well under this large power load, demonstrating the viability of usin g water-cooled diamonds for high-intensity synchrotron radiation beamlines.
