Times Cited Count：23 Percentile：77.15(Physics, Nuclear)The pointing stability and divergence of a quasimonoenergetic electron bunch generated in a self-injected laser-plasma acceleration regime using 4 TW laser is studied. A pointing stability of 2.4 mrad root-mean-square (RMS) and a beam divergence of 10.6 mrad (RMS) were obtained using an argon gas-jet target for 50 sequential shots, while these values were degraded by a factor of three at the optimum condition using helium. The peak electron energies were 8.5
0.7 MeV and 24.83.6 MeV using argon and helium, respectively. The experimental results indicate that the different propagation condition could be generated with the different material, although it is performed with the same irradiation condition.

The stability and collimatability of quasi-monoenergetic electron beam production in the self-injected laser-plasma acceleration regime are studied. The collimation of electron beam drived by terawatt femtosecond laser (4.5 TW, 40 fs) is measured at two species of gas material (Helium gasjet and Argon gasjet). We measured 3.2 mrad pointing stability and beam divergence of 11 mrad (r.m.s.) at Argon gasjet for 50 continuous shots. At such condition, the peak electron energy is 9.11.6 MeV. For Helium, the pointing stability is three times larger than that of Argon. It is considered that the laser channel formation is important role for stable electron beam generation.

The collimatability of quasi-monoenergetic electron beam production in the self-injected laser-plasma acceleration regime is studied. The collimation of electron beam drived by terawatt femtosecond laser (4.1 TW, 40 fs) is measured at two species of gas material (Helium gasjet and Argon gasjet). We measured 3.2 mrad pointing stability and beam divergence of 11 mrad (r.m.s.) at Argon gasjet for 50 sequencial shots. At such condition, the peak electron energy is 9.11.0 MeV with 80% reproducebility. For Helium, the pointing stability is three times larger than that of Argon. It is considered that the laser channel formation is important role for stable electron beam generation.
