Transverse and Longitudinal Beam Diagnostics using Transition Radiation

The broad spectrum of transition radiation emitted from a thin foil in the beamline carries in principle all the proper- ties of the beam, producing it. The optical part of the spec- trum (OTR) allows to extract the transverse beam infor- mation via beamspot imaging with the use of commercial CCD cameras. The combination of a CCD and graphical data processing tools provides the operator the transverse beam parameters fast and in a comfortable way. The energy spread of the electron beam is determined with the same system by projecting the energy distribution on a transverse axis in a dispersive section of the beamline. Transition ra- diation in the far infrared enables bunch length measure- ments in the ps range with an autocorrelation technique. The bunch length was measured to be ps, this was confirmed by a streak camera measurement.
