Date/Time: Thu Dec 11 2025 at 14:00<br/><br/>Location: Auditorium / Zoom<br/><br/>Speaker: Alex Gottberg (TRIUMF)<br/><br/>Title: ARIEL at the Finish Line: Delivering TRIUMF?s Next-Generation RIB Capabilities<br/><br/>Abstract: TRIUMF stands on the verge of a major scientific milestone. With ARIEL, we are completing a facility that will not only triple our rare-isotope beam (RIB) capacity but redefine what is possible for RIB science in Canada. After years of coordinated design, engineering, and prototyping, ARIEL?s proton- and electron-driven target stations are nearing readiness ? each enabling new isotopes, greater reliability, and unprecedented parallel beam delivery.
As we approach the Long Shutdown of 2026, we have a unique and time-critical opportunity: by coordinating installation and commissioning activities across TRIUMF, we can complete the ARIEL project within just a few years and position the laboratory for initial user-beam delivery as early as 2027/28. This colloquium will outline the current completion status of the ARIEL target stations, highlight the recent offline qualification of their core components, and present updated predictions for beam intensities and scientific reach. Finally, I will discuss the integrated roadmap toward ARIEL?s full capability, emphasizing the collective effort required ? and the strong momentum already in place ? to bring this magnificent new facility across the finish line.

Room<br/><br/>Speaker: Alexandre Beaubien (University of Victoria)<br/><br/>Title: Design and Construction of a Polarized Electron Source for the Chiral Belle Upgrade to the SuperKEKB Collider<br/><br/>Abstract: The SuperKEKB collider delivers e+e- collisions at the world's highest instantaneous luminosity for the Belle II experiment. A proposed long-term Chiral Belle upgrade aims to introduce a polarized electron beam in the High Energy Ring (HER), enabling a new and unique program of precision physics.
In order to introduce a polarized electron beam in the HER, a low-emittance polarized electron source is required. This source will supply transversely polarized electrons with the ability to flip polarity allowing for separate data sets with opposite polarization states. This talk presents the design, simulation and construction of a GaAs-based polarized electron source for the preliminary phase of the upgrade. The source was designed and built at KEK, thanks in part to the KEK?TRIUMF Exchange Program for Early Career Researchers (EPECR).

Although photons are most commonly used as a radiation modality, alternative forms of ionizing radiation such as proton, electron, and heavy ions have steadily gained popularity, exhibiting distinct physical and biological advantages over conventional photon-based techniques. In parallel, novel dose delivery techniques like FLASH radiotherapy and spatially fractionated radiotherapy (SFRT) are particularly promising in their potential to enhance the therapeutic window. However, their observed benefits remain insufficiently understood, especially when comparing responses across different particle types. Progress in this field is hindered not only by limited access to specialized research facilities but also by the technical challenges associated with accurately characterizing highly dynamic and spatially complex irradiation fields.
Over the past two years at the University of Bern, Dr. Kasanda have led the upgrade of a research beamline to enable pre-clinical proton radiobiology research using a commercial medical cyclotron that is mainly used for radioisotope production. This upgrade includes the implementation of novel beam shaping and diagnostic elements alongside ongoing detector developments. Through a collaboration with the University of Bern Institute of Anatomy, our facility aims to support comparative studies investigating biological response to proton versus photon irradiation for FLASH, SFRT, and combined treatment strategies in the next year, providing critical insight into the relationship between delivered radiation fields and biological outcomes.
At TRIUMF, this work can be expanded significantly by taking advantage of the varied and extensive accelerator infrastructure and irradiation facilities. With access to megavolt photons, higher-energy protons, electrons, and heavy ions, TRIUMF offers a unique opportunity to advance these comparative radiobiology studies across multiple particle types. My project will focus primarily on the development of dosimetry protocols and detector systems capable of characterizing these irradiation fields with high temporal and spatial precision, forming the foundation of a robust experimental platform for such studies.
While these developments directly support the advancement of cancer treatment research, they also hold broader relevance to research disciplines relying on accurate beam characterization. Ultimately, this work seeks to bridge technical innovation with biological insight, enabling more reliable experimentation and accelerating the clinical translation of advanced radiation therapy techniques.<br/><br/>.<br/><br/>______________________________<br/><br/>Detailed information available can be found at <a href='https://www.triumf.ca/research-program/lectures-conferences/upcoming-seminars-lectures'>https://www.triumf.ca/research-program/lectures-conferences/upcoming-seminars-lectures</a> <br/><br/>
