The injector cryomodule for E-Linac at TRIUMF

The e-Linac project at TRIUMF, now funded, is specified to accelerate 10 mA of electrons to 50 MeV using 1.3 GHz multi-cell superconducting cavities. The linac consists of three cryomodules; an injector cryomodule with one cavity and two accelerating modules with two cavities each. The injector module is being designed and constructed in collaboration with VECC in Kolkata. The design utilizes a unique box cryomodule with a top-loading cold mass. A 4 K phase separator, 4 K / 2 K heat exchanger and JouleThomson valve are installed within each module to produce 2 K liquid. The design and status of the development are presented.
