Liquid argon time projection chamber (LArTPC)

A Liquid Argon Time Projection Chamber (LArTPC) is a scientific detector used to study tiny particles called neutrinos. It uses a large tank of ultra-pure liquid argon, which is a cold, clear substance. When a neutrino interacts with the argon atoms, it creates tiny charged particles that leave trails of electric signals. These signals are collected by sensitive wires over time, allowing scientists to create detailed, three-dimensional images of the particle interactions. This helps researchers understand fundamental properties of particles and the universe’s basic building blocks.
