Symmetry features

Test beams generally sit to the side of full-on accelerators, sipping beam and passing it to the reconfigurable spaces housing temporary experiments. Scientists bring pieces of their detectors — sensors, chips, electronics or other material — and blast them with the well-understood beam to see if things work how they expect, and if their software performs as expected. Before a detector component can head to its forever home, it has to pass the test.

Today, as vice president of research at the University of Colima in Mexico, Alfredo Ananda’s main occupation is building a more certain route to a research career for Latin American students. He does this by providing them with challenging academics and international connections.

Advances in subatomic physics heavily depend on ingenuity and technology. And when it comes to discovering the nature of some of the most elusive particles in the universe, neutrinos, scientists need the best and most sensitive detector technology possible. Scientists working at CERN have started tests of a new neutrino detector prototype, using a very promising technology called “dual phase.”

Latin America has reached a pivotal moment in experimental particle physics and astrophysics research. Throughout the month of October, Symmetry will highlight important places, explain significant milestones, and introduce you to some of the people who have shaped and are continuing to shape particle physics and astrophysics in Latin America.

Working on hardware doesn’t come easily to all physicists, but Francesca Ricci-Tam has learned that what matters most is a willingness to put in the practice.
