ABSTRACT
There is great interest in the generation of energy-tunable, bright, short-pulse X/ γ-ray sources, which are required in various research fields. Laser-Compton scattering (LCS) is considered to be one of the most promising methods to implement this kind of X/ γ-ray source. At the 100-MeV LINAC of the Shanghai Institute of Applied Physics, a 2-J, 8-ns, 1064-nm, Q-switched Nd:YAG laser is brought to a slanting collision at 40° (44°) with an 112-MeV, 0.9-ns (rms) relativistic electron beam. We measured the LCS X-ray energy spectrum with a peak energy of 31.73±0.22±1.64 keV and a peak width (rms) of 0.74±0.26±0.03 keV. This preliminary investigation was carried out to understand the feasibility of developing an energy-tunable X/ γ-ray source. Based on this study, the future Shanghai Laser Electron Gamma Source (SLEGS) at the Shanghai Synchrotron Radiation Facility (SSRF) can be constructed to be not only an energy-tunable γ-ray source by guiding the laser incident angle from laser-Compton scattering, but also a high flux (∼10 photons/s or even higher) γ-ray source by adding a laser super-cavity.

    In this experiment, 32S interaction with emulsion nuclei is examined at 3.7A and 200A GeV. Backward relativistic hadron production seems to be an exact decay system, depending on the target size. For emulsion nuclei, the decay constant of this system nearly equals 1.3. Independent of the...

    A new method of laser acceleration of electrons is proposed. The method is based on stimulated Compton scattering in a noncollinear geometry. The saturation length is found to be rather small. The scheme with a varying geometry is suggested to prevent the process from saturating and to achieve...
