A prototype revolver undulator was installed at Sector 35 of the U.S. Department of Energy’s Advanced Photon Source (APS) at Argonne National Laboratory during the January 2015 shutdown. This inser- tion device will provide the new Dynamic Compression Sector (DCS) with the benefits of two undulators in the space of one. In a matter of minutes, the active undulator magnet structure can be switched between a 3.3-cm period and a 2.7-cm period. This arrange- ment allows higher x-ray brightness and flux over a broader energy range than could be achieved with a single conventional undulator. The installa- tion is the culmination of a multi-year Argonne Laboratory Directed Research and Development (LDRD) program carried out by the Magnetic Devices Group in the Accelerator Systems Division to develop a robust revolver undulator platform for near-term use at the APS. The platform is also expected to be further developed in conjunction with a future upgrade of the APS. The demands for precise, fail-safe positioning of powerful undulator magnetic arrays, in close proximity to the vacuum cham- bers that house the electron beam, must be met by all of the APS undulators. But the revolver undulator must also precisely index the two sets of magnetic arrays, and be safeguarded against more complex failure modes. Toward this end, the revolver undulator uses the well-proven gap separation mechanism of the most-recent 33 APS undulators, and applies the same interlock and control scheme to the revolver mechanisms. The use of this gap separa- tion mechanism also allows future repurposing of these mecha- nisms as revolver undulators. The revolver undulator that was installed at Sector 35 is the final prototype of the revolver undulator LDRD program, and bene- fits from post-LDRD development primarily focused on control soft- ware. The first “production” revolver undulator is undergoing assembly at the APS, with installation at Sector 35 planned for May 2015. That device uses 3.0-cm period and 2.7-cm period magnet structures. The new revolver undulator can accommodate undulator magnet struc- tures up to 2.4-m long. Any combina- tion of the APS-designed undulator magnet structures, from 1.72-cm to 3.6-cm periods can be used. All of the functions of the conventional undulator are retained, including gap tapering. The revolver undulator is compatible with all of the APS insertion device vac- uum chambers, but requires the inser- tion device vacuum chamber support stands to be retrofitted to a new design.

A prototype revolver undulatorwas installed at Sector 35 of the U.S.Department of Energy’s AdvancedPhoton Source (APS) at ArgonneNational Laboratory during theJanuary 2015 shutdown. This inser-tion device will provide the newDynamic Compression Sector (DCS)with the benefits of two undulators inthe space of one.
In a matter of minutes, the activeundulator magnet structure can beswitched between a 3.3-cm periodand a 2.7-cm period. This arrange-ment allows higher x-ray brightnessand flux over a broader energy rangethan could be achieved with a singleconventional undulator. The installa-tion is the culmination of a multi-year Argonne Laboratory DirectedResearch and Development (LDRD) program carried out by theMagnetic Devices Group in the Accelerator Systems Division todevelop a robust revolver undulator platform for near-term use atthe APS. The platform is also expected to be further developed inconjunction with a future upgrade of the APS.
The demands for precise, fail-safe positioning of powerfulundulator magnetic arrays, in close proximity to the vacuum cham-bers that house the electron beam, must be met by all of the APSundulators. But the revolver undulator must also precisely index thetwo sets of magnetic arrays, and be safeguarded against morecomplex failure modes. Toward this end, the revolver undulatoruses the well-proven gap separation mechanism of the most-recent33 APS undulators, and applies the same interlock and controlscheme to the revolver mechanisms. The use of this gap separa-tion mechanism also allows future repurposing of these mecha-nisms as revolver undulators.
The revolver undulator that was installed at Sector 35 is thefinal prototype of the revolver undulator LDRD program, and bene-fits from post-LDRD development primarily focused on control soft-ware.
