It is proposed to replace the 7 Tesla wavelength shifter, which has been operating in CAMD since 1998, with a superconducting Multi Pole Wiggler (MPW). This will have 11 main poles with peak fields of 7.5 Tesla and will be accommodated in a cryo-cooled cryostat whose overall length will be 2.5 m. It will be necessary to modify the storage ring lattice parameters in order to inject into the reduced 20 mm vertical aperture of this MPW. The results are presented of tests which have been made of several different lattice configurations which have low vertical beta at the proposed location of the MPW.

The superconducting wiggler (SCW) with 4.2 Tesla field in 5 main poles has been in operation on the NSLS X-ray storage ring for more than 20 years. The inefficient cryogenic system of this wiggler uses a closed-cycle refrigerator requiring constant maintenance. It is possible to replace this insertion device with a 13-pole SCW originally built by Oxford Instruments. The cryostat of this device could be upgraded to reduce the liquid He consumption using cryocoolers, thereby greatly reducing the refrigerator operating expense. A second option is a new design of a SCW with a magnetic period and number of poles appropriate to the current users needs. All these upgrade possibilities will be described in the paper.
