Applications of Muons

Muons Spin Spectroscopy (muSR)

Rich application scenarios^[1]

• Magnetism
• Quantum systems
• Superconductivity
• Energy materials
• Dynamics in soft matter

Time reversal symmetry breaking in Sr₂RuO₄^[2]

Quasi-static and dynamic spins in NaYbSe₂^[3]

Muon Induced X-ray Emission (MIXE)

• A non-invasive, multi-elemental analysis.
• Implantation depth is controlled by (negative) muon momentum.
• Depth profiling from nm – cm^[1].

•

Muon Catalyzed Fusion

• Nuclear fusion requires extreme conditions.
• Muons can promote nuclear wavefunction overlap by chemical confinement (vs magnetic)^[5].
• First observed in bubble chamber by Alvarez.
• Current research focus on Increasing µCF cycles per lifetime and new kinematic mechanisms.
