Abstract Advanced Photon Source is in the process of developing an upgrade of the storage ring. The Upgrade will be converting the current double bend lattice to a multi-bend lattice (MBA). In addition, the storage ring will be operated at 6 GeV and 200 mA with regular swap-out injection to keep the stored beam current constant. The swap-out injection will take place with beamline shutters open. For radiation safety to ensure that no electrons can exit the storage ring, a passive method of protecting the beamline and containing the electrons inside the storage ring tunnel is proposed. A clearing magnet will be located in all beamline front ends inside the storage ring tunnel. This article will discuss the principle, design and mechanical design of the clearing magnet scheme for the APS-Upgrade.
