The array contained C268600100020 14 dE-E telescopes each consisting of a 1.5 mm thick C268600100021 double-sided Si strip dE detector followed by a 4-cm- C268600100022 thick CsI(Tl) E detector. The dE detectors are 6.4 cm C268600100023 x 6.4 cm in area, with each face divided into 32 C268600100024 strips. Each E detector consisted of four separate C268600100025 CsI(Tl) elements, each spanning a quadrant of the C268600100026 preceding Si detector. C268600100027 METHOD (EDE) C268600100028 INC-SOURCE Secondary beam of 13-O was produced from primary 16-O C268600100029 beam on Be target at energy of 150 MeV/A. The beam C268600100030 was purified using the A1900 magnetic spectrometer C268600100031 and the radio frequency fragment separator and had an C268600100032 intensity of 10+3 pps with purity of 80%.
