Focal plane detector systems for Beijing G120 Q3D Magnetic Spectrometer

The requirements for the important characteristics of the focal plane detector systems which are equipped with Q3D magnetic spectrometer are proposed based on the features of HI 13 Tandem accelerator and the performances of the spectrometer as well as the requirements of physics researches. The detailed descriptions are made for the particle identification of the combined systems of the spectrometer and the detectors. The technical parameters for the detector modal are given and the possibly obtained performances of detectors are estimated and the ways to correct them are described. The real performances for both light detector and heavy ion detector have been practically used are given by means of experimental tests.
