Notes:
A new filter has been designed at Argonne National Laboratory that is intended for the use in undulator/wiggler beamlines at the Advanced Photon Source. The water-cooled frame allows up to four individual filter foil banks simultaneously in the beam path. Additionally, the bottom of each frame holds two thin (20 μm) uncooled carbon filters in tandem for low-energy filtering. Therefore a maximum of 625 filter selection combinations is theoretically possible. The design is compact and modular, with great flexibility for the users. To prevent accidental movement of the filter, effort has been taken to provide a mechanically locked, fail-safe actuator system. Programming aspects are under development as part of the general personnel and equipment protection system to provide an intelligent control system. Aspects of the design and operational principles of the filter are presented in this paper. © 1995 American Institute of Physics.
