The 7Li(p,n)7Be gr.st. 2270500100010 (Q=-1.644 MeV) and 7Li(p,n)7Be (0.431 MeV) reactions 2270500100011 produced at 0 degr. lab. angle a quasimonoenergetic 2270500100012 neutron beam. Using a 3-mm-thick lithium target and 2270500100013 a 10**(-5)A proton beam, about 10**6 n/s are available 2270500100014 at the location of reaction chamber (around 3m 2270500100015 downstream from the lithium target). 2270500100016 FACILITY (CYCLO,2BLGLVN) 2270500100017 DETECTOR (TELES) Four charged-particle detector telescopes are 2270500100018 used simultaneously. Each of them consists of a deltaE 2270500100019 detector (NE102 pl.scin., 0.1 mm thick, 4cm in diam.) 2270500100020 viewed by an XP2020 photomultiplier via lucite light 2270500100021 guide, and an E detector (CsI(Tl) crystal, 22 mm thick 2270500100022 38.2mm in diam.), viewed by an XP2262B photomultiplier.2270500100023 For energy calibration of the detectors the protons and2270500100024 deuterons recoiling from a polypropylene (1 or 0.5 mm 2270500100025 thick) and a 0.6-mm-thick deuterated polypropylene 2270500100026 target, respectively, are used. 2270500100027 (SCIN) The neutron-beam radial distribution measured 2270500100028 with NE102 scin. ( 5mm in diam.) 2270500100029 SAMPLE An elemental carbon target (5x5 cm2 surface and 1 mm 2270500100030 thick. The angle of the target with the beam was chosen2270500100031 to minimize the thickness of the target material 2270500100032 traversed the produced charged particles towards 2270500100033 telescopes. 2270500100034 MONITOR The beam monitoring system is realized in two ways. 2270500100035 Behind the lithium target, the incident proton beam is 2270500100036 deflected by a magnetic dipole into a water-cooled 2270500100037 Faraday cup which serves as beam monitor. 2270500100038 Second: The integral of the recoil proton peak. A 2270500100039 charged particle telescope detects at 45 degr. 2270500100040 the H(n,p) scattered protons. It consists of a NE102 2270500100041 (2-mm-thick) scin. as delta-E and a CsI(Tl) crystal as2270500100042 E detector. 2270500100043 METHOD (TOF) 2270500100044 ERR-ANALYS (ERR-1) The uncertainty of the cross section absolute 2270500100045 scale. 2270500100046 5%- the measured reference (n,p) cross sections 2270500100047 2%- beam monitoring 2270500100048 2%- statistics in the H(n,p) recoil proton peak 2270500100049 1%- solid-angle corrections 2270500100050 1%- number of target nuclei 2270500100051 (ERR-2) Relative error 2270500100052 STATUS (SPSDD,22303001) duplication with 22303 2270500100053 HISTORY (20010330C) SD 2270500100054 (20060911A) Correlation established 2270500100055 (20101105D) SD: Entry deleted.
