We obtained low transverse momentum spread ( ptrans/p= 1.610 $^{-2}$ ) electron bunch from 500 m-scale rare gas target using 2-TW laser beam with long-focus configuration. This value is 2/3 times lower than that from LBL result. In particular, we obtained energy boosting from sub-MeV to 30-MeV class by the multi-stage acceleration. We would like to report on the experimental result mainly.
