TRIUMF, Vancouver
TRIUMF, in collaboration with university partners, proposes to construct a megawatt-class electron linear accelerator (e-linac) as a driver for U(γ,f) with rates up to 1013−1014 fissions/sec for Rare Isotope Beams (RIB) for nuclear structure and astrophysics, and 9Be(γ,p)8Li for materials science. The emphasis would be on neutron-rich species. The 50 MeV, 10 mA, c.w. linac is based on TTF superconducting radiofrequency technology at 1.3 GHz & 2K. Many of the major sub-system components have been identified; where possible existing designs will be adopted. The first stage of the project, a 25 MeV, 5 mA, c.w. linac matching the isotope production target power-handling capability in the next five-year plan, is to be completed in 2013. The injector cryomodule (ICM)development, which is being fast tracked, is the subject of a scientific collaboration between TRIUMF and the VECC laboratory in Kolkata, India. The paper gives an overview of the accelerator design progress with emphasis on the ICM.
