Web1 de abr. de 2024 · Experimental measurements of the response of BF 3 detector to a 3 Ci Am–Be neutron source for three different reflecting materials, i.e., aluminum, wood, and Perspex of varying thicknesses have been carried out. The varying contribution of wall effect to the response due to change in active volume of the detector has also been determined … WebNeutron capture cross section measurements in time-of-flight facilities are usually performed by detecting the prompt gamma-rays emitted in the capture reactions. One of the difficulties to be addressed in these measurements is that the emitted gamma-rays may change with the neutron energy, and therefore also the detection efficiency.
