Phys. Rev. ST Accel. Beams 12, 032801 (2009) [9 pages]Absolute bunch length measurements by incoherent radiation fluctuation analysis
By analyzing the pulse to pulse intensity fluctuations of the radiation emitted by a charge particle in the incoherent part of the spectrum, it is possible to extract information about the spatial distribution of the beam. At the Advanced Light Source of the Lawrence Berkeley National Laboratory, we have developed and successfully tested a simple scheme based on this principle that allows for the absolute measurement of the rms bunch length. A description of the method and the experimental results are presented. This article is available under the terms of the Creative Commons Attribution 3.0 License.
