Vacuum Technology: Keys and Applications. Conceptional Design for Vacuum Systems of Synchrotron Radiation Beamlines.

Vacuum System Design of the Third Generation Synchrotron Radiation Source

Within the next two years the 2.3 km long storage ring PETRA will be rebuild into one of the most brilliant x-ray sources worldwide (PETRA III). The large bending radius and the use of damping wigglers allow to achieve small beam emittances and extremely brilliant x-ray beams. In this paper we describe the design and the expected performance of the vacuum system for the storage ring. It consist...

Prospects for studying vacuum polarisation using dipole and synchrotron radiation

The measurement of vacuum polarisation effects, in particular vacuum birefringence, using combined optical and X-ray laser pulses are now actively pursued. Here we briefly examine the feasibility of two alternative set-ups. The first utilises an alternative target, namely a converging dipole pulse, and the second uses an alternative probe, namely the synchrotron-like emission from highly energe...

VUV synchrotron radiation studies of candidate LHC vacuum chamber materials

For the design of future accelerators, in particular, the beam vacuum of the large hadron collider (LHC), a 27 km circumference proton collider to be built at CERN, ‘white light’ (WL) and monochromatic VUV synchrotron radiation (SR) have been used to measure, both qualitatively and quantitatively, electron emission from candidate vacuum chamber materials. Emphasis has been placed on measuring t...

Optical Beamlines for the KEK B-Factory Synchrotron Radiation Monitors

We have designed and constructed two optical beamlines for the KEK B-Factory synchrotron radiation monitors, one for each ring. Each beamline transports the SR beam 30-40 meters to an external optics hutch along two parallel paths. One path is used for direct imaging with adaptive optics[1], the other is used for transverse beam size measurements via SR interferometer[2] and longitudinal profil...
