F101800100004 AUTHOR (D.F.Measday,P.S.Fisher,A.Kalmykov,F.A.Nikolaev, F101800100005 A.B.Clegg) F101800100006 INSTITUTE (2UK OXF) F101800100007 REFERENCE (J,NP,45,98,1963) F101800100008 FACILITY (LINAC,2UK OXF) F101800100009 DETECTOR (NAICR) Gamma-radiation from the target was detected atF101800100010 90 degr. to the proton beam in a sodium iodide crystal,F101800100011 15cm long and 12.5 cm diameter, viewed initially by an F101800100012 EMI photomultiplier type 6099 and later by an RCA F101800100013 photomultiplier type 7046 with a faster rise-time, the F101800100014 front face of the crystal being 15 cm from the target F101800100015 centre. The counter was housed in a lead cylinder of F101800100016 wall thickness 10 cm. As the beam in the experimental F101800100017 area was contained inside the vacuum pipe by quadrupoleF101800100018 magnets, the Faraday cup and the carbon collimator wereF101800100019 the only important sources of background. Further lead F101800100020 shielding was therefore placed between the counter and F101800100021 these two sources. With these shielding arrangements F101800100022 the target-out background was less than 10% of the F101800100023 target-in counting rate. F101800100024 SAMPLE The target was of polythene 5 cm2 mounted on a brass F101800100025 frame which could be retracted from the beam without F101800100026 breaking the vacuum. Targets of two different F101800100027 thicknesses were used. Target A was used at proton F101800100028 energies below 30 MeV and target B above that energy.
