Teams working on TRIUMF’s Advanced Rare Isotope Laboratory (ARIEL) achieved a major milestone for the facility’s electron linear accelerator (e-linac) by reaching an average beam power of 10 kW at the e-linac's design energy of 30 MeV. The results, which come nearly three months ahead of schedule, mark a major leap in the ramp-up of the accelerator’s output to full capacity and eventual operation.
