Situated at the middle of the second Radioactive Ion Beam Line in Lanzhou(RIBLL2),the External Target Facility(ETF)has been constructed for reaction studies with high-energy secondary beams of several hundred MeV/u.The charged fragment detector system of ETF consists of a dipole magnet,tracking drift chambers,ionization chambers and plastic scintillators for particle identification via B-ΔE-TOF method.After more than ten years of R&D on detectors,electronics,data acquisition system and data analysis framework,the charged fragment detector system of ETF has completed its test runs and ready to produce scientific data。
