L015400100012 DETECTOR (MAGSP) 2-m-long spin-precession solenoid was placed L015400100013 on a neutron flight path. Solenoid was able to L015400100014 precess a 3.26 MeV neutron through an angle of pi/2. L015400100015 At the end of the 9m flight path the neutrons were L015400100016 scattered from the natural C analyzing target. L015400100017 (SCIN) Neutron scattered from the C target up (+50 L015400100018 deg) and down (-50 deg) with respect to (g,n) L015400100019 reaction plane were detected by plastic scintillator L015400100020 with dimensions 20 x 10 x 5 cm**3, located 35 cm L015400100021 from the C target L015400100022 METHOD (LRASY) The polarization of the photo-neutrons was L015400100023 determined by observing the asymmetry in their L015400100024 scattering from a C target placed at the end of a 9 L015400100025 m flight path. L015400100026 (TOF) Photoneutron energy was determined by time-of- L015400100027 flight over flight path of 9 m. L015400100028 INC-SOURCE (BRST) Pulsed electron beam with energy of 19 MeV L015400100029 striked an air cooled graphite block. Peak beam L015400100030 current was 15 A with pulse duration of 4 ns and L015400100031 repetition rate of 800 Hz. L015400100032 HISTORY (20101015C) Compiled by S.H.
