In-vacuum Undulators

چکیده
The so-called in-vacuum undulators, in which magnet arrays are installed inside the vacuum chamber, have been proved to be a promising way toward shorter wavelength of synchrotron radiation (SR). Especially, it has been adopted in lots of medium-scale SR facilities to provide angstrom x rays to carry out protein-crystallography experiments. Needless to say, there have been a number of technical challenges to be overcome for realization of in-vacuum undulators. For example, some measures have to be taken to achieve ultra high vacuum enough to be installed in the storage ring, field correction schemes should be established for utilization of higher harmonics, and so on. Most of these technologies have been established in SPring-8, in which more than 20 in-vacuum undulators have been installed.

Recent Advances in the Generation of Pulsed Synchrotron Radiation Suitable for Picosecond Time-Resolved X-ray Studies
We describe the beamline optics, the shutters and the femtosecond laser used in pump & probe experiments down to 50 picosecond resolution. The performance of in-vacuum undulators is compared to in-air undulators. It is concluded that single-harmonic in-vacuum undulators are optimal for pump and probe experiments based on single-bunch exposures. These low-K undulators can produce a spectral flux...
متن کاملPushing the Limits of Short Period Permanent Magnet Undulators
Short period undulators to be used as FEL radiators permit lower electron energies and, thus, reduced linac and undulator lengths. The first X-ray FEL facility based on in-vacuum permanent magnet undulators has gone into operation, already (SACLA). Another in-vacuum undulator based X-FEL is planned (SWISS-FEL). The in-vacuum undulators have period lengths of 18mm (SACLA) and 15mm (SWISS-FEL), r...
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 کاملUpgrade of the Insertion Devices at the Esrf
An important upgrade of the ESRF is planned from 2009 to 2016. The upgrade is mainly driven by the improvement of beamline performance and capacity. On the storage ring side, the length of the straight sections will be increased from 5 m to 6 m with a possible further extension to 7 m. These long sections will provide a higher photon flux, and will allow the installation of canted undulators. T...
متن کاملR&d towards a Delta-type Undulator for the Lcls*
The LCLS generates linearly polarized, intense, high brightness x-ray pulses from planar fixed-gap undulators. While the fixed-gap design supports a very successful and tightly controlled alignment concept, it provides only limited taper capability (up to 1% through canted pole and horizontal position adjustability) and lacks polarization control. The latter is of great importance for soft x-ra...
