TRIUMF ARIEL Science Workshop 2026

The ARIEL (Advanced Rare IsotopE Laboratory) Science workshop will be held at TRIUMF during April 20 – 23, 2026.  

The ARIEL facility will begin a phased commissioning of the equipment and beamlines starting from 2027. This will bring access to enhanced rare-isotope-beams (RIB) capabilities at TRIUMF with multidisciplinary benefit for nuclear-physics, material-science and life-sciences programs. The unique feature of ARIEL will be the operation of three simultaneous rare isotope beamlines.  

There will be new capability of production of neutron-rich species using electron-induced photofission with a 30 MeV and up to 10 mA electron beam (eLINAC), on a new advanced electron target station.  There will be an additional second proton beamline leading to a new proton target station.  For beam preparation and delivery there will be a new ARIEL Laser Ion Source capability, an electron beam ion source (EBIS) for the production of pulsed, highly charged beams with high efficiency, and a high-resolution mass separator.   

The establishment of these beamlines and facilities will allow simultaneous delivery of RIB to three separate experiments, two to the low-energy area for stopped and trapped beams and one to the ISAC linear accelerator path for re-accelerated rare isotope beams of energies ranging from 0.15 MeV/u to 16.5 MeV/u.  

For the best scientific exploitation of this new era of rare isotopes at TRIUMF, we wish to invite the global community to participate in the ARIEL Science Workshop to explore experiment ideas for ARIEL-enabled science. This  workshop will be devoted to nuclear science.  

The scientific program will consist of invited oral and contributed poster presentations as well as round table discussion sessions. The workshop will aim to build collaborations to prepare for the first experiments with ARIEL and to explore the development of new instrumentation for experiments.
