Abstract
A (CF2)n-PIN sandwiched detecting array with statistics enhancement in low pulsed y flux measurements has been constructed. The array uses 2mm thick (CF2)n overlaid with Si-PIN detector of φ60 mm × 1000 μm, then coupled to PA101 amplifier with gain 100. The array exhibits four distinct properties: (1) very high detecting efficiency: The y detecting sensitivity of the array can reach 10-11C·cm2, which is 4 orders of magnitude higher than that of a signal PIN detector of φ20 mm × 250 μm; (2) remarkable statistics enhancement: The statistics enhancement of the array has been studied with M-C simulation, which displays highly enhanced statistics in very low pulsed γ flux measurement; (3) huge dynamic range: A single array can cover seven orders of magnitude's measurement range of γ flux; and (4) flat response in given y energy range. The array has found its applications in experimental measurements.
