Short pulse synchrotron light from Jefferson Lab´s nuclear physics accelerator

There has been recent interest in developing sources of X-rays, both coherent and incoherent, for advanced materials science and other scientific studies. In particular, there is interest in developing so-called fourth generation light sources, which are driven by electron linacs. One distinguishing feature of the fourth generation sources is the very short pulse length, usually under 1 psec rms, that is possible from a linac driven source. Because of recent successes in achieving very short bunches out of its injector, it is natural to investigate whether the Jefferson Lab nuclear physics accelerator might be used as a copious source of incoherent short-pulse synchrotron light. In this note we present the results of calculations of the expected synchrotron radiation spectrum from bend magnets at four locations in the CEBAF accelerator. The results show that substantial numbers of short pulse X-rays are produced
