The primary beam 60 MeV/u 13C was provided by HIRFL, bombarding the beryllium target (4 mm in thickness). The 6He secondary beam was then chosen by setting the Bρ, purified by passing the aluminum wedge degrader with a mean thickness of 1mm and identified by measuring the TOF and △E at T2 of RIBLL.
