The TRIUMF eLINAC, currently in its design phase, is a 50MeV electron linear accelerator and will be used for photo-fission to produce rare isotopes for experiments. Future upgrade plans include an option to go to a recirculating LINAC to provide higher energies. This brings up the need to calculate the shunt impedances of higher order modes (HOM) to avoid beam instabilities and beam break up (BBU). The cavity design for a 9 cell cavity has to account for the limitations given by the desired beam current of 10mA and the layout of the recirculating path to create a high enough BBU limit. Work on the cavity design to accommodate for the HOM requirements will be presented as well as a way to reduce the shunt impedance by the use of ring dampers will be discussed.
