Abstract: In the present paper， it is introduced the scientific background and the current status of the high precision spectroscopy of the molecular ions at cooler storage ring. The advantages to study the dissociative recombination(DR) processes using cooler storage ring CSRe are discussed. The physics design，the main parameters of the injection beam line and the injection of the molecular ions into the CSRe and the key techniques are described in detail. With a new injection beam line，HIRFL-CSRe will be reconstructed to a multidiscipline research platform，offering good opportunities for the study of DR processes of molecular ions，especially for that of the molecular ions of m>70 amu with much improved resolution.
