Outgoing neutrons at different angles 2100000100019 are used to get differently polarized neutrons. 2100000100020 SAMPLE Same as detector 3. 2100000100021 METHOD (TOF,ASSOP,COINC) Flight paths 16 and 30 cm. 2100000100022 To obtain the energy spectrum of the scattered 2100000100023 neutrons, the time-of-flight difference between the 2100000100024 scattered neutron and the associated alpha-particle 2100000100025 from the neutron production is measured. 2100000100026 To reduce the background, a coincidence was required 2100000100027 between the associated alpha particle (production) 2100000100028 and the recoil deuteron ( elastic scattering). 2100000100029 For the asymmetry measurements the whole set-up 2100000100030 remained fixed and only the incident neutron 2100000100031 polarization was reversed. 2100000100032 DETECTOR (SCIN) Thin plastic scintillator to detect the 2100000100033 associated alpha particles at 90 degrees with respect 2100000100034 to the deuteron beam.
