Laser based 100 GeV electron acceleration scheme for muon production.

Area of Science:

• Particle Physics
• Accelerator Physics
• Plasma Physics

Background:

• High-energy muons offer unique deep penetration capabilities for radiography.
• Conventional muon sources rely on large, GeV-TeV particle accelerators.
• Laser wakefield acceleration (LWFA) provides much higher acceleration gradients, enabling compact accelerators.

Purpose of the Study:

• To propose and simulate a compact muon source concept.
• To leverage LWFA for efficient electron acceleration.
• To estimate muon production from the simulated electron beam.

Main Methods:

• Self-consistent Particle-In-Cell (PIC) simulations.
• All-optical laser wakefield acceleration with a guiding channel.
• Analysis of electron energy spectrum to estimate muon yield.

Main Results:

• Achieved 100 GeV electron energies in a 6-meter accelerator.
• Demonstrated a compact, single-stage LWFA for high-energy electrons.
• Estimated potential for high-energy and high-flux muon production.

Conclusions:

• The proposed LWFA-based accelerator is a viable concept for a compact muon source.
• Integration with high-average-power laser technology is key for a practical source.
• This technology could revolutionize muon radiography and related fields.
