Abstract：
In this paper, the theoretical background of OTR (abbreviation for Optical Transition Radiation) is stated, the principle of applying OTR to beam diagnostics is described, the schemes of experiments on an electron beam of 18MeV, 2.7kA are presented. In intense electron beam diagnostics, there are many difficulties,such as target destruction,X-ray noise,electron-magnetic disturbance,and so an. After overcoming these difficulties,the characteristic pattern of OTR with and without polarizing glass are both obtained. The conclusion that polarizing glass should be used in beam diagnostics is deduced after analyzing the difference between the two patterns.With OTR method,the beam profile,energy,divergence are measured.OTR and Cerenkov Radiation are used simultaneously to measure the normalized beam emittance.In this experiment,OTR is used to measure the energy and divergence,and Cerenkov Radiation is used to measure the profile.
