A New Algorithm for Assigning Fluxpoint Energies to Solid State Detector Passbands
Abstract
Solid-state particle telescopes generate data in the form of counts detected within a range of energy/nucleon values; when several adjacent ranges (passbands) are monitored, it is possible to infer the energy spectrum of the underlying particle flux. However, since the discrete counts represent the integral of the flux over a passband, there is no way to unambiguously assign an exact flux at an exact energy. For ions above 1 MeV/nuc, the differential flux usually approximates a power law of the form dJ/dE = A E-γ. We discuss different methods for assigning a fixed energy to each passband, the rationale behind using the geometric mean, and the use of a "bowtie" analysis. Finally we introduce a best-fit method for assigning passband energies representative of a wide variety of γ values.
