Measurement Method for High-Energy Gamma Radiation Based on Copper Activation

Laser-driven relativistic electron beams exhibit properties including ultra-short pulses, high energy levels, and substantial charges, finding significant applications in fields such as overheated electron transport, rapid electron beam ignition, electron imaging, and the generation of ultrashort X/Y radiation sources and neutron sources. These beams represent forefront research topics in the fields of high-energy density physics, strong field physics, and laser nuclear physics.
