Statistical Nature

Signal-induced background has a time dependence that distinguishes it from the sources discussed in Chapter 6. These events refer to a progression in which a signal generates a subsequent one, correlated in time to the initial detection. The timescale for correlated background ranges from nanoseconds to days. The earliest signal is a prepulse generated by a photon incident on d1. Late pulses relate to the k-to-d1, and k-to-anode transit time. The next category, the afterpulses, spans ~100 ns to 10 μ‎s, with a peaked time distribution. There is a long-lived source of photons, extending to days and caused by exposure of a photomultiplier to bright light or to nuclear radiation. Afterpulses contribute to the slope of a photon-counting plateau characteristic, distort fluorescent decay, and pulse shape discrimination measurements. They also affect resolution, and processes of a statistical nature.

AbstractThe experiment SONG (SOlar Neutron and Gamma rays) for the low altitude satellite CORONAS-I is described. The instrument is capable to provide gamma-ray line and continuum detection in the energy range 0.1 – 100 MeV as well as detection of neutrons with energies above 30 MeV. As a by-product, the electrons in the range 11 – 108 MeV will be measured too. The pulse shape discrimination technique (PSD) is used.
