Abstract
The intensity and energy spatial distributions of collimated laser Compton scattering (LCS) γ-ray beams and of the associated bremsstrahlung beams have been investigated as functions of the electron beam energy, electron beam phase spac...

The beam size in newSUBARU strongly depends on the stored current of electron beam in the single-bunch mode operation. The measurement method is very simple, that is, just see the spot size of radiation from bending magnets by a CCD camera. In the...

The beam commissioning of the 1.5 GeV electron storage ring of "NewSUBARU" started in September 1998. At the beginning of the commissioning the beam lifetime was short because of the high beam-on pressure. The upgrade of the vacuum system includin...
