Title:     Imaging of Relativistic and Non-relativistic Charged–particle Beams with OTR

Abstract: The characterization of transverse beam sizes of lepton and hadron beams using optical transition radiation (OTR) imaging has been a well-established technique at many accelerator facilities. The preponderance of the cases has  involved relativistic beams in the past.  Example results for particle beams at ANL (7-GeV electrons) and Fermilab (120-GeV protons) will be described.  A brief review of an OTR model will be shown for both OTR and coherent OTR from microbunched beams as time permits. In addition, recent experimental interest in non-relativistic beam cases for low-beta beams at CERN and Fermilab will be presented. The latter may have relevance to the ARIEL project at TRIUMF.

Stimulants available 15 minutes before the talk.
