"Scientists Successfully Capture 4D 'Ghost' in CERN Accelerator"

Physicists at CERN have successfully measured and quantified a 4D resonance structure in the Super Proton Synchrotron particle accelerator, which can cause beam degradation and hinder particle research. This structure, resulting from a phenomenon known as resonance, requires four states to represent and affects the path of particles in the accelerator. By carefully measuring particle positions, the researchers were able to map the resonance and demonstrate how individual particles behave within it. Understanding this phenomenon could lead to new ways to mitigate beam degradation and achieve high-fidelity beams for future particle acceleration experiments.
