Title
Calculation of background effects on the VESUVIO eV neutron spectrometer
Contributors
J Mayers (STFC Rutherford Appleton Lab.)
Abstract
The VESUVIO spectrometer at the ISIS pulsed neutron source measures the momentum distribution n(p) of atoms by "neutron Compton scattering" (NCS). Measurements of n(p) provide a unique window on the quantum behaviour of atomic nuclei in condensed matter systems. The VESUVIO (superscript)6Li doped neutron detectors at forward scattering angles were replaced in Feb 2008 by Yttrium Aluminium Perovskite doped (YAP) gamma-ray detectors. These provide a much superior resolution and general performance, but suffer from a sample dependent gamma background. This report details how this background is calaculated and data corrected. The report also indicates how this background can be reduced.
