Invited Oral

In recent work, the first quantitative measurements of electron beam vertical emittance using a vertical undulator were presented, with particular emphasis given to ultralow vertical emittances*. Using this apparatus, a geometric vertical emittance of 0.9 +- 0.3 pm rad has been observed. A critical analysis is given of measurement approaches that were attempted, with particular emphasis on...

In the LHC, the beam halo due to higher beam energy and intensities will increase the impact on LHC machine protection and on luminosity performance. Measurement of the beam halo distribution is therefore important for understanding and controlling the beam halo. A coronagraph was designed for the observation of the beam halo population. A new optical design of the coronagraph is made for the...

30. Recent Progress in X-Ray Emittance Diagnostics at SPring-8

Contributed Oral

Synchrotron radiation in the X-ray range is suitable for non-destructive diagnostics of beam emittance *. Both direct imaging and interferometric techniques can resolve the micrometer-order transverse beam size. The beam emittance is obtained from the measured beam size with the knowledge of the betatron and dispersion functions and the beam energy spread. At the SPring-8 storage ring, we have...
