内容記述 | Laser wakefield acceleration (LWFA) [1] has been studied intensively in the past decades. With the optimization of chirped pulse amplification technology (CPA) [2], high quality electron beams with energies over GeV [3] have been generated. The ultrahigh acceleration gradient allows for the construction of a table top x-ray free electron laser [4]. To achieve lasing in the x-ray wavelength range, GeV class electron beam with high brightness is necessary. We succeeded generating highly collimated quasi-monoenergetic electron beams with peak energies up to GeV via ionization-injection [5, 6] using the J-KAREN-P laser. By incident of 300 TW laser pulses into a 10 mm gas jet, comparison studies were performed with pure (He), (He:Ne) mixture and (He:N2) mixture gases. We observed that the divergences, energies and charges of electron beams have dependences on gas species and mixture ratios. The smallest divergence of electron beams from (He:Ne) was merely 0.18 mrad (rms), which was 5 times smaller than that from (He:N2) gas. For many shots, we got extremely high charge electron bunches at plasma denties lower than the self-injection threshold. This study shows the capabilities of the ionization injection regime manipulate and optimize the qualities of the GeV class electron beams from laser wakefield acceleration. |
