Diamagnetic effects in synchrotron sources

Synchrotron IRadiation Sources

Synchrotron Light Sources

YNCHROTRON RADIATION sources have proven to be immensely important tools throughout the sciences and engineering. In consequence, synchrotron radiation usage continues to grow, assuring the need for additional synchrotron radiation machines well into the foreseeable future. Storage rings, the basis for all major existing hard X-ray synchrotron facilities, have inherent limitations that constrai...

Synchrotron-driven Spallation Sources

The use of synchrotrons for pulsed neutron spallation sources is an example of spin-off from the accelerator development prompted by particle physics. The first proposal for an accelerator-driven source with a thermalised neutron facility was in the 1960s (Intense Neutron Generator, ING) [1], but this project was never built. There was earlier work on 'electrical' breeders [2] and the direct bo...

Beam Stability in Synchrotron Light Sources*

Numerous third-generation light sources are now in a mature phase of operation, and several new sources are under construction. Submicron beam stability is being achieved routinely at many of these light sources in terms of both AC (rms 0.1 200 Hz) and DC (one week drift) motion. This level of stability is a necessary condition for the success of x-ray free-electron lasers such as the Linac Coh...

Propagation-induced Circular Polarisation in Synchrotron Sources

The small degree of circular polarisation observed in some synchrotron sources has a frequency dependence that is not consistent with simple predictions based on the intrinsic circular polarisation of synchrotron emission. The suggestion is explored that the circular polarisation arises as a propagation effect within the source. The physical basis of this alternative mechanism is the fact that ...
