Shielding design calculation for SPring-8 beamlines using STAC8.

The beamlines of SPring-8 are classified by synchrotron radiation source into undulator, wiggler and bending-magnet beamlines for safety analysis. The shielding design calculations for synchrotron radiation are performed with a new shielding design code, STAC8, taking into consideration the linear-polarization effect, the slant length of the shield hutch wall and the build-up effect as functions of scattering angle and azimuthal angle.
