A compact filter/mask/window assembly has been designed for undulator beamline commissioning activity at the Advanced Photon Source beamlines. The assembly consists of one 300-{mu}m graphite filter, one 127-{mu}m CVD diamond filter and two 250-{mu}m beryllium windows. A water-cooled Glidcop fixed mask with a 4.5 mm{times}4.5 mm output optical aperture and a 0.96 mrad{times}1.6 mrad beam missteering acceptance is a major part in the assembly. The CVD diamond filter, which is mounted on the downstream side of the fixed mask, is designed to also function as a transmitting x-ray beam position monitor. The sum signal from the latter can be used to monitor the physical condition of the graphite filter and prevent any possible chain reaction damage to the beryllium windows downstream. In this paper, the design concept as well as the detailed structural design of the commissioning window are presented. Further applications of the commissioning window components are also discussed. {copyright} {ital 1996 American Institute of Physics.}
