摘　　要：Based on the successful dielectronic recombination(DR)experiments with intermediate charge state ions of Belike Ar^(14+[1]) and Ca^(16+[2]) at the CSRm,we are preparing the precision spectroscopy of DR experiments with highly charged ions and even radioactive ions at the CSRe.A test electron-ion recombination experiment of Boron-like Ar13+ions was performed with a section of the new electron beam energy detuning system,which will be installed at the CSRe.Fig.1 presents the measured and also the calculated DR spectra for B-like Ar^(13+) from 0 to 3 eV.The experimental result indicates that the new detuning system is more stable and has a higher energy resolution than the previous detuning system used at the CSRm.It paves the way for the upcoming DR experiments with highly charged heavy ions at the CSRe.In addition,the flexible atomic code(FAC)was employed to calculate the DR resonance strengths of Boron-like Ar^(13+) to compare with the experimental result.
