【Abstract】 With the development of accelerator technologies, it is important to find a rapid and precise way in which the electron spectrum can be diagnosed on real time. For its advantages of relatively simple setting-up, fast response, little disturbance to a beam and so forth OTR (Optical Transition Radiation) technologies has gradually attracted our attention. In this article real time spectrum analysis on OTR technologies was introduced. The prelimicnary result from parts of the instrument was listed and studied. The width of OTR was 20mm, in accordance with the theoretical result.更多还原
