Getting your Trinity Audio player ready...

Dr. Blair Jamieson, a physicist hailing from the University of Winnipeg, accompanied by his investigative team, is garnering a wave of admiration as they gear up to journey to the European Organization for Nuclear Research, colloquially known as CERN, in Switzerland this fall. CERN is globally lauded as one of the most esteemed and expansive scientific research centers.

In the realm of scientific exploration, Dr. Jamieson is etching his legacy as he spearheads a groundbreaking initiative intended to enrich our understanding of elementary interactions and fine-tune neutrino observations. Collaborating with him in this avant-garde project are Faculty of Graduate Studies pupil Mahnoor Mansoor, currently stationed at CERN, Postdoctoral Associate Ali Ajmi, and MITACS undergraduate scholar Andera Mayorga, originating from Mexico. Dr. Jamieson expounds, “The procurement of this invaluable data from enhanced neutrino observations will significantly fortify existing neutrino studies, thus invigorating extraordinary scientific endeavors around the world.”


Decoding Neutrino Enigmas

At CERN, the group headed by Dr. Jamieson is set to conduct pivotal research of tremendous significance. Their commitment will assist in deciphering the mysteries associated with neutrinos through the refinement of measurement methodologies. This initiative, which builds on his earlier work from the Hyper-Kamiokande experiment in Japan, is a crucial step towards the development of a measurement system that is more precise. The international collaboration team is getting ready for a beam test using a conventional particle detector called a hodoscope in order to fulfill their goals. This instrument is specially designed to differentiate among distinct gamma ray energies. Dr. Jamieson’s proficiency in engineering will play an indispensable role in the success of the experiment, guaranteeing accurate and reliable outcomes through the use of a lead glass calorimeter for the detailed quantification of these gamma ray energy levels.

A Vision in Detail

Furthermore, Dr. Jamieson’s team at UWinnipeg is now assembling a collection of ultra-high-resolution camera systems for photogrammetry of the water Cherenkov detectors. This undertaking involves plunging eight camera encasements into water. The submerged housings and camera circuitry are in the process of being readied in Room 3L10 on campus.

With the arrival of fall, the responsibility of installing these in the water Cherenkov detector will fall to Ajmi. Concurrently, Mayorga is exploring camera calibration to rectify distortion and grasp the uncertainties in spatial reconstruction from the photos taken underwater. This ambitious project’s main goal is to distinguish amongst neutrino and anti-neutrino fluctuations, which has the potential to greatly improve our understanding of these fundamental particles. Dr. Jamieson’s group is not just making a significant contribution to the global scientific community, but also stirring the interest of aspiring physicists to participate in groundbreaking research endeavors.


Beam it up!

The particle beam trial at CERN forms a crucial preliminary phase for the Water Cherenkov Test Experiment (WCTE), a scaled-down replica of the Intermediate Water Cherenkov Detector (IWCD) designed for Hyper-K. Addressing a significant ambiguity in the current line of water Cherenkov detectors, this examination will permit the differentiation between gamma rays and electrons. Utilizing the assistance of CERN’s T9 beamline, exact energy levels of muons, electrons, pions, and gamma rays will be steered into the water Cherenkov detector, allowing comprehensive evaluation. Jamieson emphasizes the worth of the information extracted from these assessments, highlighting its potential to enhance reconstructions via both traditional and machine learning techniques.

The Hyper-K detector, expected to commence operations in 2027, is poised to revolutionize the field of particle physics. It will enable precise gauging of neutrino and anti-neutrino oscillations and pave the way for the investigation of CP violation. Years of combined endeavors by an international consortium of researchers, featuring Canadian institutions such as the University of Victoria, BCIT, TRIUMF, Carleton University, and University of Regina, have culminated in this electrifying upcoming stage of exploration. A character as unique as Dr. Sheldon Cooper would find joy in the fascinating outcomes derived from Dr. Jamieson’s efforts at CERN and the mesmerizing journey of unraveling neutrino enigmas.
