C259300100014 DETECTOR (SCIN) Neutrons were detected by three NE213 liquid C259300100015 organic scintillators with diameter of 12.7 cm and C259300100016 thickness of 5.08 cm. Detectors were placed at an C259300100017 angle of 105 deg and distance of 5 m from the target C259300100018 METHOD (TOF) Neutron energy was determined by time of flight C259300100019 (TOF). Beam of 3He was chopped and bunched to cca 3 C259300100020 ns bunches with frequency of 2.5 MHz. The TOF start C259300100021 signal was obtained from the neutron detector and a C259300100022 TOF stop signal provided the capacitive pick-off C259300100023 located upstream of the target chamber.
