TRIUMF has embarked on a 1.3GHz development program to support the construction of a 50MeV 10mA e-Linac for the production of radioactive ion beams through photo-fission. Two single cell bulk niobium cavities have been produced in Canadian Industry. A seven-cell cavity in copper is being fabricated both as a manufacturing model and to test higher order mode calculations. Electro-magnetic and mechanical models of a multi-cell cavity are being done to optimize the final design for high intensity acceleration. The 1.3GHz cavity development program will be presented.
