Mechanical Design of NSLS Mini-gap Undulator (MGU)
نویسندگان
چکیده
The mechanical design considerations are discussed with respect to the currently installed X-13 and future X-29 MGU. Comparisons to the previous 2 generations of variable small-gap undulator evolution in the NSLS X-ray ring are made and design improvements noted. The design requirements and mechanical difficulties for holding, positioning and driving the magnetic arrays are explored. Structural, thermal and electrical considerations which influenced the design are then analyzed. The mechanical performance of the MGU currently installed at X13 is examined and future installations and enhancements are presented.

Mechanical Design of Nsls X-25 Small Gap Undulator
The mechanical design considerations are discussed with respect to the X-25 small gap in-vacuum hybrid permanent magnet and vanadium permendur undulator, currently under design at the NSLS. Performance predictions, mechanical, thermal and structural design methodology, both common to undulators of this type, and unique to the subject undulator, are discussed. The design requirements and mechani...
متن کاملNsls In-vacuum Undulators and Mini-beta Straights
We review the work carried out in the X13 R&D Straight Section of the NSLS X-Ray Ring on small gap in-vacuum undulators (IVUNs). Then we discuss: (1) plans to replace the pure permanent magnet undulator in X13 by a hybrid design providing stronger magnetic fields, enhancing the tunability of the device; (2) plans to install hybrid IVUNs in the two RF straights of the X-Ray Ring, increasing the ...
متن کاملInitial results from an in-vacuum undulator in the NSLS X-ray ring.
A short-period in-vacuum undulator for the NSLS X-ray Ring has been developed in a collaboration between SPring-8 and the NSLS, and has achieved its project design goals during commissioning studies. The device is called IVUN (in-vacuum undulator) and employs magnet arrays (31 periods, with an 11 mm period) developed at SPring-8, while the requisite vacuum chamber and mechanical systems were de...
متن کاملBeamline X29: a novel undulator source for X-ray crystallography.
A high-flux insertion device and beamline for macromolecular crystallography has been built at the National Synchrotron Light Source (NSLS) that employs a mini-gap undulator source developed by the NSLS. The mini-gap undulator at beamline X29 is a hybrid-magnet device of period 12.5 mm operating at proven gaps of 3.3-10 mm. The beamline provides hard X-rays for macromolecular crystallography ex...
متن کاملSmall-gap Undulator Experiment on the Nsls X-ray Ring"
We report results of an on-going experiment being carried out in the X13 straight section of the NSLS X-ray Ring which explores the limits of the operation of small-gap undulators. In particular, we discuss measurements of stored electron beam lifetime as a function of the vertical aperture presented by a 4-jaw scraper or a variable-aperture vacuum vessel. At an electron beam current of 300 mA ...
