Produced neutrons were 2353200100019 slowed down in a supercritical para hydrogen 2353200100020 moderator. 2353200100021 The proton beams were supplied at a repetition rate of 2353200100022 25 Hz and under a proton beam power of 200 kW. 2353200100023 By controlling the opening window, the frame overlap 2353200100024 chopper facilitated expansion of the neutron energy 2353200100025 down to 0.2 meV. 2353200100026 -1st frame: 0.8 meV < En < 1 eV, 2353200100027 -2nd frame: 0.2 meV < En < 0.6 meV) 2353200100028 SAMPLE Nano diamond powder. (natural carbon) 2353200100029 The powder was shaped into a plate by pressing. 2353200100030 -Sample weight: 37.5 mg 2353200100031 -Sample shape: 10 mm x 10 mm x 0.57 mmt 2353200100032 -Average size of nano diamond powder: 5.1 nm 2353200100033 Homogeneity of the sample was measured with 2353200100034 neutron transmission imaging method. 2353200100035 Homogeneity uncertainty was estimated to be 1.8%. 2353200100036 The plate was stored in a pure aluminum capsule 2353200100037 with thickness of 0.3 mm. 2353200100038 A 0.3-mm thick cadmium plate with an 8-mm hole 2353200100039 at its center was placed on the aluminum capsule. 2353200100040 DETECTOR (HE3SP) The 3He detector was covered with boron 2353200100041 carbide resin and equipped with an opening slit of 2353200100042 10 mm x 20 mm. 2353200100043 METHOD (TRN) Cross sections are deduced from neutron 2353200100044 transmission ratio measured with the nano diamond 2353200100045 sample to that measured without the sample. 2353200100046 (TOF) Flight length = 14.665 m 2353200100047 ANALYSIS The incident neutrons were normalized against incident 2353200100048 protons to the facility. 2353200100049 HISTORY (20190910R)
