Here is what the page “Proton Surfing: Moving Plasma Waves Push Laser-Driven Ions to Record Energies” contains. Researchers have demonstrated a new method to accelerate protons to record energies using long-pulse lasers and a moving plasma wave, akin to a surfer riding a wave. The technique, detailed in a recent study, overcomes a key limitation of laser-driven ion acceleration: the vulnerability of ultrathin targets to the laser's prepulse. By using a specially tailored plasma density profile, the team created a 'moving wave' that continuously accelerates protons, achieving energies previously unattainable with such long pulses.
This advance matters because it could lead to more compact and cost-effective particle accelerators for medical treatments, such as cancer therapy, and for scientific research. The work, led by scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and published in Nature Physics, shows that protons can be accelerated to over 100 million electron volts (MeV) using a laser pulse lasting a few hundred femtoseconds—a significant step toward practical applications.
