XIA filter bank/shutter modules

Modules from XIA (PF4 and PF2S2) are used at both 1-ID and 1-BM. The Model PF4 is designed to reproducibly attenuate an x-ray beam by inserting up to four filter foils under remote manual or computer control. In the Model PF2S2 , thick absorber blades replace two filters to form a focal plane shutter.

The PFCU-4 is a flexible control unit for both Model PF4 Filter Inserters and Model PF2S2 Filter/Shutter Units. In a 1-wide NIM module, it implements both manual control, via front panel switches, and remote control, via either TTL I/O or RS-232 daisy chain.
