英文摘要	In the fast ignition scheme, in order to deliver enough energy (10kJ) into the pellet in lOps, the ignition laser beam should reach the intensity of I-0 similar to 10(20)W/cm(2) if the coupling from the laser to the core plasma is about 20% for a well-collimated beam. However, studies have shown that the electron divergence increases with the laser intensity. Of particular importance is the possibility of collimating the fast electron beams with the size of the compressed core. In this work, we will introduce two ways to obtain the collimated electrons: 1) collimate fast electrons in specially engineered targets with the spontaneously generated magnetic field during its transportation; 2) collimate fast electrons with imposed magnetic field.; EI; CPCI-S(ISTP); cai_hongbo@iapcm.ac.cn; 1; 688
