Abstract:
Muon radiation background of China Jinping Underground Laboratory (CJPL) was simulated by Monte Carlo method. According to the Gaisser formula and the MUSIC soft, the model of cosmic ray muons was established. Then the yield and the average energy of...

Abstract:
The effect of self-generated magnetic field of electron beams produced by laser irradiating on metal wires on the divergence of the electron beams is studied. The theoretical analysis and magnitude order estimation show that, between the laser spot a...
