- W2072368595 abstract "Abstract The source has been manufactured from 239Pu enriched with 24 per cent of 240Pu and has been cast in the form of a homogeneous sphere 3 cm in diameter clad in gold. Spontaneous fission accounts for more than 97 per cent of the output the remainder being contributed by (α, n) reactions. Calculations show that the energy spectrum of the emergent neutrons differs only slightly from the 240Pu fission spectrum. Absolute determinations of the source output have been made using three independent flat response detectors; namely, the Aldermaston Oil Bath standardized by the T(d, n)4He reaction, the Harwell Boron Pile standardized by the D(y, n)H reaction and the National Physical Laboratory Manganese Sulphate Bath the efficiency of which is determined by adding to the inactive bath a known amount of 56Mn activity. Details of these three calibrations are given with particular reference to the Oil Bath method since this has not been described in the literature to the extent of the other two. Excellent agreement has been obtained, a weighted average giving a mean neutron emission rate of (6·562 ± 0·029) × 104 n/sec referred to January 1964. The source output is increasing slightly with time at a rate of about 0·1 percent per year, the present strength being 6·579 × 104 n/sec (June, 1966)." @default.
