F117800100004 AUTHOR (M.C.Scott) F117800100005 INSTITUTE (2UK BIR) F117800100006 REFERENCE (J,JNE,25,405,1971) F117800100007 #doi:10.1016/0022-3107(71)90077-3 F117800100008 FACILITY (CYCLO,2UK BIR) F117800100009 DETECTOR (NAICR) A well shielded counting chamber containing a F117800100010 3.7 cm diam., 2.5 cm high sodium iodide crystal. F117800100011 (SCIN) Scintillation counters for monitoring of gamma F117800100012 rays. F117800100013 METHOD (BCINT,TTM) F117800100014 SAMPLE The target, 2-5 cm dia., was coupled to the end of a F117800100015 56 cm long, 2-5 cm dia. thin-walled stainless steel F117800100016 tube, insulated with PTFE from the rest of the F117800100017 apparatus. F117800100018 ERR-ANALYS Random errors attributable to individual measurements F117800100019 were in the current measurement (0.3-0.95%), in the F117800100020 estimation of the asymptotic count rate (0.09-2.17%) F117800100021 and in the fraction of the protons striking the walls F117800100022 of the Faraday cup (0.5%). Systematic errors arose F117800100023 from uncertainties in the F117800100024 (ERR-1) counter dead time, F117800100025 (ERR-2) the manganese half-life, F117800100026 (ERR-3) the bath calibration factor, and from the F117800100027 bath correction factors. The ranges in the latter F117800100028 case were: F117800100029 (ERR-4,0.04,0.2) oxygen and sulphur losses, F117800100030 (ERR-5,0.18,0.66) leakage F117800100031 (ERR-6,0.15,0.51) absorption in the target and F117800100032 structural materials. The random errors have been F117800100033 summed in the usual way, the systematic error is the F117800100034 linear sum of its components, and the final error is F117800100035 the linear sum of these two.
