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. F101800100029
