There’s a specter haunting the tunnels of a particle accelerator at CERN.
In the Super Proton Synchrotron, physicists have finally measured and quantified an invisible structure that can divert the course of the particles therein, and create problems for particle research.
It’s described as taking place in phase space, which can represent one or more states of a moving system. Since four states are required to represent the structure, the researchers view it as four-dimensional.
This structure is the result of a phenomenon known as resonance, and being able to quantify and measure it takes us a step closer to solving a problem universal to magnetic particle accelerators.
“With these resonances, what happens is that particles don’t follow exactly the path we want and then fly away and get lost,” says physicist Giuliano Franchetti of GSI in Germany. “This causes beam degradation and makes it difficult to reach the required beam parameters.”
