Title: Parametric mechanical design of new insertion devices at the APS.

Abstract

Three permanent-magnet, planar, hybrid insertion device (ID) designs have recently been completed at the APS. The periods of these undulators are 2.7 cm, 3.0 cm and 3.5 cm with nominal lengths of 2.4 m. Several design studies were performed for the initial 2.7-cm-period device. Then a parametric solid model for the initial device was developed and value engineered to minimize manufacturing, assembly and tuning costs. The model allowed the very rapid design of subsequent devices of similar periods and allowed commonality of several components of the IDs. This design family incorporates a low-cost method of pole retention and registration. Poles are secured by screws in two holes tapped into each pole. Pole location is registered by means of two small dowel pins in mating holes reamed into each pole and a 'divider' plate common to the poles and magnets. This divider plate is flexible along its length so shimming behind it can be used to accurately change the height of a pair of poles for tuning. Another feature of the design is modular construction to allow each device to be used full length or shortened to a nominal 2.1 m length for use in APS 'canted undulator' sectors.
