The (∆E 1 , ∆E 2 , E) multidetector telescope has been developed and tested. The telescope is a compact combination of two 32-strip silicon ∆E 1 -, ∆E 2 -detectors and a scintillation E-detector, which is a 3 × 3 array of CsI(Tl) crystals. A timing signal can be obtained from any of the Si detectors for time-of-flight (TOF) measurements. Single-channel and 32-channel charge-sensitive preamplifiers have been developed and manufactured for the multidetector module to serve the ∆Eand Е-detectors with high efficiency and sensitivity. Reaction products obtained in the 40 Ar (35 MeV/nucleon) + 9 Ве reaction have been unambiguously identified in the experiment by mass number A and atomic number Z.

The basic ion optical characteristics of the luminosity and the high resolution of kinematic sep arator COMBAS realized for the first time on the strong focusing principle are presented. The developed facility allows to separate the high intensity secondary radioactive beams in a wide range of mass numbers A and atomic numbers Z which are produced in heavy ion reactions in the energy range of 20 ≤ E ≤ 100 MeV/A (Fermi energy domain). Two distinct detector systems such as realized Si strip detector telescope and the promising development of the three dimension time projection chamber are discussed. Program of the inves tigations of nuclear reaction mechanisms at intermediate energies of 20-100 MeV/A, measurement of the radii of unstable nuclei, study of the cluster structure of light nuclei near the nuclear drip line and search of 26,28 O resonances in exchange reactions is proposed. The upgrading of experimental facility by the integration of COMBAS separator with the Ion Catcher is discussed.
