One sprinkle of sand at a time, two artists have recreated the moment a particle passed through a detector 30 years earlier. Their piece, a bright blue and white sculpture of tracks of microscopic bubbles in a bubble chamber, was inspired by the Tibetan Buddhist tradition of the sand mandala. To find the perfect bubble chamber image to recreate, they scrolled through hundreds of these photographs in the archive at Fermilab.
From FAPESP, Feb. 13, 2019: Uma parte vital de um dos maiores experimentos da física de partículas atual foi desenvolvida no Brasil. O Arapuca é um detector de luz a ser instalado no Deep Underground Neutrino Experiment — projeto que busca descobrir novas propriedades dos neutrinos, partícula elementar com muito pouca massa e que viaja a uma velocidade muito próxima à da luz.
Fermilab has enormous, decades-long experience in building silicon detectors. Thanks to an exceptional, cooperative team with levels of experience and capabilities that lead the world, we were able to quickly put together a design for a tracking system that could be used for muon tomography — using muons to see inside solid objects, similar to how we use X-rays. The system won an R&D 100 Award.
Fermilab’s quantum program includes a number of leading-edge research initiatives that build on the lab’s unique capabilities as the U.S. center for high-energy physics and a leader in quantum physics research. On the tour, researchers discussed quantum technologies for communication, high-energy physics experiments, algorithms and theory, and superconducting qubits hosted in superconducting radio-frequency cavities.
The new technology is a miniaturized version of a sensor developed for the CMS experiment at the Large Hadron Collider. But instead of being used for discovery science, the sensors are developed to screen cargo by detecting muons, particles that penetrate materials such as concrete and lead. Scientists at Fermilab, Los Alamos National Laboratory and the Nevada National Security Site designed, assembled and tested the small, slim sensors, which could replace bulkier screening technologies.
From FAPAESP’s Pesquisa, Oct. 18, 2018: Em meados de setembro, partículas vindas do espaço começaram a atravessar um tanque em forma de cubo com 6 metros de altura, instalado na Cern, na Suíça, e deixar rastros de luz que foram captados por detectores criados no Brasil.
