A compensating watercooled crystal bender for high heat loads has been built and successfully commissioned at the new multipole wiggler beamline MAGS of the Hahn-Meitner-Institute at the synchrotron radiation source BESSY. The beamline takes a 3 x 0.3 mrad fan of the wiggler beam, corresponding to a heat load of up to 2000 W. Although the crystal bender was originally designed for maximum heat loads of 600 W, it was found to work with heat loads of up to 800 W, reducing the Si(111) rocking curve width from 17.2 to 8.3 arcsec at the Cu K-edge (8.9 keV). In addition, the good mechanical reproducibility of the device is illustrated.
