Since 2007 TRIUMF started development of eLINAC which is a 50 MeV 10 mA CW electron superconducting linear accelerator to be used as a driver to produce radioactive ion beams through photofission. The accelerator is based on five 1.3 GHz TTF/ILC elliptical bulk Nb cavities technology to be mounted in three cryomodules; an injector cryomodule with one cavity and two accelerating modules with two cavities each. The ISAC-II project superconducting heavy ion linear accelerator was successfully completed in 2010 and we now have in operation 40 superconducting bulk Nb QWR cavities assembled in eight cryomodules. Results and plans of the SCRF program and experience of ISAC-II operation at TRIUMF will be discussed.

This paper concerns numerical simulations and experimental investigation of multipacting discharge in accelerating cavities and feeding waveguide section of eLINAC accelerator. The threshold values of accelerating gradient and input power for discharge may occur in these structures have been obtained experimentally and compared to numerical predictions. Secondary emission influence on discharge behavior were also considered.

Results on coupling increase research for biperiodic accelerating structure featuring high effective shunt impedance and other electrodynamical characteristics are presented. Accelerating structure for sample facility was designed taking into consideration thermal issues and multipactor discharge immunity.
