What does "ProtoDUNE" mean?
Table of Contents
ProtoDUNE refers to a series of experiments aimed at helping scientists better understand neutrinos, some of the most elusive particles in the universe. These experiments take place at CERN, the famous research facility in Switzerland that gave us the World Wide Web and a bunch of really smart folks in lab coats.
What is ProtoDUNE?
ProtoDUNE consists of two large-scale prototypes called ProtoDUNE-HD and ProtoDUNE-VD. Each of these prototypes contains 750 tons of liquid argon. That’s a lot of argon! Think of it as a giant, super cool party in a tank where scientists are trying to uncover the secrets of the universe.
Why Liquid Argon?
Liquid argon is special because it can help detect certain kinds of light produced when particles interact. This light is called scintillation light, and it can tell scientists when and how particles are having their little dance parties in the tank. The Photon Detection System (PDS) is the gadget that catches this light and helps piece together the action.
DUNE's Goals
The main goal of the Deep Underground Neutrino Experiment (DUNE) is to study how neutrinos change from one type to another, known as oscillation. This is important because it may help scientists understand why our universe is made mostly of matter rather than antimatter. Spoiler alert: No one really knows yet!
Searching for New Physics
ProtoDUNE is not just resting on its laurels; it’s also on the lookout for mysterious particles that don’t fit into our current understanding of physics. This includes particles that might be responsible for dark matter, the mysterious stuff that makes up most of the universe but is shy about interacting with normal matter.
Fun Times Ahead
By using ProtoDUNE, scientists hope to unlock new knowledge about the universe in a very short time. And the best part? They can do this without disturbing the usual experiments happening at CERN. So, it’s like having a big pizza party without making a mess in the kitchen!
In summary, ProtoDUNE is all about getting closer to the hidden secrets of the universe, one particle at a time, while having a little fun along the way.
