- W1567307994 abstract "The large difference in initial ionization can be used to limit the size of alpha pulses relative to fission pulses in an ionization chamber, if the track lengths are both short. In parallel plate chambers this condition is not well met. A spherical plate chamber in which the ratio of maximum/minimum track length is 3 has been developed. In the present (small sample) version, the maximum track is 6 mm, with deposit and neutron beam diameters of 1 cm. At optimum, with pure CH/sub 4/ gas, an electron collection time of approximately 22 ns is expected across the 2 mm gap. It is expected that the worst alpha/fission current pulse ratio will not exceed 1/14. Thus fissile isotopes with alpha half lives of 30 years or more (e.g. /sup 243/Cm) may be studied with 1-2 nanosecond risetime current amplifiers; in addition, very small spontaneous fission branching ratios may be better determined. Comparisons of this new chamber with a parallel plate chamber and initial results on /sup 245/Cm (approximately 16 ..mu..g sample) are presented. The ORELA pulsed neutron source permits measurements below 20 eV which are inacessible to underground explosion experiments. (auth)" @default.
