In the first phase of ongoing collaboration between VECC (India) and TRIUMF (Canada) a 10 MeV superconducting electron linac injector will be installed at VECC. This will constitute a 100 keV DC thermionic gun with grid delivering pulsed electron beam at 650 MHz. Owing to low energy from the gun, a capture cryo-module (CCM) consisting of two β = 1 single cell elliptical cavities (frequency = 1.3 GHz) will be inserted before a 9-cell β = 1 elliptical cavity that will provide acceleration to 10 MeV. The present paper depicts the beam dynamics simulation and optimization of different parameters for the injector with a realistic simulated beam emittance from the electron gun.

  TRIUMF is collaborating with VECC on the design of a 10 MeV injector cryomodule to be used as a front end for a high intensity electron linac. A electron gun and low energy beam transport (LEBT) have been installed in a test area to act as the injector for the cryomodule test. The LEBT includes a wide variety of diagnostics to fully characterize the beam from the gun. A series of beam tests are being conducted during the stage installation. The test configuration details and results of beam tests will be presented.

  The ISAC accelerator complex now can accelerate radioactive heavy ion beams to above the Coulomb Barrier. Recently an ECR type charge state booster has been added to allow the acceleration of radioactive beams with masses A>30. A characteristic of the ECR source is the efficient ionization of background species that can overwhelm the low intensity RIB beam. The long linac chain at ISAC can be used to provide some in flight separation both in time domain and in spatial domain analogous to fragment separators at in-flight fragmentation facilities. The talk will summarize the work done at TRIUMF to develop tools to aid in the filtration and diagnosis of beam purity in the post acceleration of charge bred beams. Marco Marchetto has been leading this effort.

  The TRIUMF Advanced Rare Isotope Laboratory (ARIEL) is funded since 2010 June by federal and BC Provincial governments. In collaboration with the University of Victoria, TRIUMF is proceeding with construction of a new target building, connecting tunnel, rehabilitation of an existing vault to contain the electron linear accelerator, and a cryogenic compressor building. TRIUMF starts construction of a 300 keV thermionic gun, and 10 MeV Injector cryomodule (EINJ) in 2012; the designs being complete. The 25 MeV Accelerator Cryomodule (EACA) follows in autumn 2013. TRIUMF is embarking on major equipment purchases and has signed contracts for 4K cryogenic plant and four sub-atmospheric pumps, a 290 kW c.w. klystron and high-voltage power supply, 80 quadrupole magnets, EINJ tank and lid, and four 1.3 GHz niobium 9-cell cavities from a local Canadian supplier. The low energy beam transport and beam diagnotics are being installed at the ISAC-II/VECC test facility. Procurement is anticipated October 2012 for the liquid He distribution system.
