Scientists Create Camera to Track Invisible Particles in 3D

Topic: Physics

Researchers at ETH Zurich and EPFL developed a new camera that can track invisible particles like neutrinos in three dimensions. This breakthrough uses advanced camera technology to reconstruct where light originated from inside a large block of scintillator material.

Physicists have long struggled to detect tiny, invisible particles called neutrinos and dark matter candidates. These particles rarely interact with ordinary matter, making them hard to spot. To improve detection rates, scientists often build larger detectors or use more precise spatial resolution. However, this approach can become complicated and expensive.

The problem is that current particle detectors divide the detector into millions of tiny units. This makes manufacturing, assembling, and reading out these individual components a major challenge.

A team of researchers at ETH Zurich and EPFL proposed a new strategy. They developed a camera system inspired by plenoptic cameras, which capture not only light intensity but also its direction. This allows the camera to reconstruct a scene in three dimensions.

The researchers used this technology to create a detector that can track particles inside a large, unsegmented block of scintillator material. Instead of dividing the detector into tiny units, the system uses advanced camera technology to pinpoint where light originated from.

This breakthrough has the potential to revolutionize particle detection and could lead to new discoveries in physics.
