Description

The nearly isolated precise measurement of vacuum contribution, Delbruk scattering, to the elastic scattering of photons of nuclei can be realized by using high-flux linearly-polarized gamma-ray sources. For the proof of principle experiment, an intense linearly polarized gamma- ray beam with an energy lower than 1 MeV should be provided. In order to examine the available gamma-ray performance at UVSOR facility by colliding a CO 2 laser with a 746-MEV electron beam, a preliminary experiment has been performed. As a result, it was confirmed that the maximum energy of the gamma-rays was slightly lower than 1 MeV and the measured gamma-ray flux was evaluated to be 4106 photons/eV/mA/W/s around the peak energy of 950keV.
