Beam diagnostics using transition radiation

Transition radiation emitted from a thin foil in the beamline has become a preferable method for cost efficient and comfortable beam diagnostics in the regime of intercepting monitors. The optical part of the produced radiation spectrum allows the use of commercial standard CCD cameras for beam spot imaging and transverse diagnostics. A full two dimensional intensity distribution can be easily provided to the operator by use of fast graphical data processing which also allows to determine the transverse beam parameters. The OTR diagnostics at the S-DALINAC is routinely used to measure the complete set of transverse beam parameters as well as to obtain the energy spread by projecting the energy distribution on a transverse axis. Furthermore bunch length measurements were made using the millimeter wavelength range of the transition radiation spectrum and an autocorrelation technique. (author)
