主　　题：charge high acceleration 

摘      要：Laser irradiation of solid targets can drive short and high-charge relativistic electron bunches over micron-scale acceleration ***,for a long time,this technique was not considered a viable means of electron acceleration due to the large intrinsic divergence(∼50°half-angle)of the ***,a reduction in this divergence to 10°–20°half-angle has been obtained,using plasma-based magnetic fields or very high contrast laser pulses to extract the electrons into the *** we show that we can further improve the electron beam collimation,down to∼1.5°half-angle,of a high-charge(6 nC)beam,and in a highly reproducible manner,while using standard stand-alone 100 TW-class laser *** is obtained by embedding the laser-target interaction in an external,large-scale(cm),homogeneous,extremely stable,and high-strength(20 T)magnetic field that is independent of the *** upcoming multi-PW,high repetition-rate lasers,this technique opens the door to achieving even higher charges(100 nC).
