The current of S018300100018 proton beam was about 3-16 uA. S018300100019 SAMPLE (5-B-11,NAT=0.80) A 6.3 ug/cm2 thick natural boron S018300100020 target (80% 11B, 20% 10B), was made by sputtering S018300100021 natural boron onto a 0.2 mm thick tantalum backing and S018300100022 was directly water-cooled. S018300100023 DETECTOR (HPGE) The capture gamma rays were observed using a S018300100024 4x4 fold segmented, Clover-type high-purity germanium S018300100025 detector, was placed in close geometry at 0 degree, S018300100026 with its front face at a distance of 29 mm from the S018300100027 target. The Clover detector has a relative efficiency S018300100028 of about 200% and a typical resolution of 2.3 keV at S018300100029 Eg=1.3 MeV. For low-energy gamma-rays, the efficiency S018300100030 was calibrated by two standard 152Eu and 60Co sources, S018300100031 for high-energy gamma-rays, the efficiency was S018300100032 determined by use of the reaction 14N(p,g)15O. S018300100033 (SCIN) An EJ-200 plastic scintillator (length=100 cm, S018300100034 width=50 cm, thickness =5 cm) was placed 10 cm above S018300100035 the Clover detector, acting as a veto to suppress the S018300100036 cosmic-ray background.
