Templates of expected measurement uncertainties for neutron-induced capture and charged-particle production cross section observables

“…The energy loss (∆E) in the thin detector, compared to the full energy of the particle (E) determined by the signal from the thicker detector, is used to identify the particle [99]. Particles that are not energetic enough to escape thin ∆E detectors can be identified using the Pulse Shape Analysis (PSA) technique [100,101], which uses characteristics of the signal in a single detector such as the rise time and the maximum of the current [97].…”

“…The particle resolving power of a detector setup can be optimized for the type and energy range of the particles that will be measured. For a recent measurement of 59 Ni(n, p) and 59 Ni(n, α) with the LENZ detector [101], the silicon detector thicknesses were optimized to allow discrimination of protons and α particles down to 4 MeV. Combined with the reaction Q-value, this allowed for the measurement of the 59 Ni(n, p) 59 Co reaction up to outgoing proton energy of (Q p − 4 MeV), and the 59 Ni(n, α) 56 Fe reaction up to an outgoing α energy of (Q α − 7 MeV).…”

“…Scattered neutrons can also interact directly with the detector materials, resulting in additional charged particles produced via reactions such as 28 Si(n, p), 28 Si(n, α), 12,13 C(n, p), and 12,13 C(n, α). These energy-dependent backgrounds can be measured and subtracted out [88,93], suppressed with data analysis thresholds [94,101], or characterized by Monte Carlo simulations using MCNP or GEANT and subtracted [102].…”
