Dose estimates for an insertion device beamline with a tapered absorber at the Canadian Light Source

A radiation study is carried out when electrons injected into the storage ring strike a tapered copper absorber beamline component at the Canadian Light Source (CLS). The dose estimates are given for the absorber and the aluminum beam pipe inside the storage ring. Also presented are dose estimates when radiation is mitigated by the storage ring shielding walls, the side wall and the ratchet wall.
