摘要：

Ionization chambers for the positron determination and nuclear charge identification of fission fragments are described with which are measured the energy E, the specific energy loss ΔE, the arrival time t and the two space coordinates x and y (or θ) of the detected fragments. Position resolutions (fwhm) of Δx≲ 0.5 mm and Δ≲ 0.4 mm (Δθ≲05°) were obtained for fission fragments from a 252Cf source. A nuclear charge resolution (fwhm) of ΔZ ∼ 2.0 was also obtained by coincidence measurements of the light ones with the gamma rays. The atomic number Z could be assigned to the respective fragments emitting each of the many prompt gamma rays in 252Cf spontaneous fission. © 1979.
