| Abstract: | ANAETF, a large data analysis framework for the External Target Facility (ETF) of HIRFL-CSR, has been developed and successfully used for data analysis in radioactive ion beam experiments. This paper covers the flow of data processing in the program, the general tracking algorithm for the drift chambers, the particle identification (PID) approach, and the techniques for extraction of reaction cross sections. The program achieves total detecting efficiencies of around ~90% and gives clear PID spectrum for carbon and beryllium fragments produced from the reaction of 240 MeV/u 12C secondary beams on a carbon target. The obtained cross sections are consistent with the previously reported experimental results. |
