"The Advanced Rare IsotopE Laboratory (ARIEL) at TRIUMF will triple the available rare isotope beam (RIB) time for experiments. The major part of ARIEL is the 50 MeV, high intensity cw eLINAC based on 1.3GHz SRF cavities. An eventual addition to the eLINAC is a recirculating beam line to allow FEL-ERL operation in addition to the RIB production beam. To avoid multipass beam break-up (BBU), the design of the SRF cavity had to be modified to reduce the shunt impedance of dipole higher order modes (HOM). Work on the cavity design and HOM load measurements will be shown as well as results of the vertical and horizontal cavity tests."
