Status of the electron beam transverse diagnostics with optical diffraction radiation at FLASH, DESY

The characterization of the transverse phase space of electron beams with high charge density and high energy is a fundamental requirement for particle accelerator facilities. The knowledge of characteristics of the accelerated beams is of great importance also for the successful development of the next generation light sources and linear colliders. In order to measure the properties of such beams, development of non-invasive and non-intercepting beam diagnostics techniques is necessary. A promising canditate is Optical Diffraction Radiation (ODR), as testified by the interest of many laboratories all around the world. At this purpose, an experiment using ODR to measure the electron beam transverse parameters has been set up at FLASH (former VUV-FEL) at DESY (Hamburg). Radiation emitted by 620 MeV electron beam passing through a 1 mm slit on a screen made of aluminum deposited on a silicon substrate is detected by a low noise, high sensitivity CCD camera.© (2007) COPYRIGHT SPIE--The International Society for Optical Engineering.
