Abstract
A series of neutron-beam-characterization measurements was carried out during the 2009 run cycle at the Manuel Lujan Jr. Neutron Scattering Center. The experimental data of time-emission spectra, reflecting the resolution of the neutron-beam pulses, were compared to measurements made in 2002, shortly after commissioning of the target-moderator-reflector-shield (TMRS) assembly. This comparison allows us to determine any possible changes to the performance (resolution) of the TMRS in its seven years in service (2002–2009). During our experimental campaign we were able to characterize four out of a total of six moderators installed in the TMRS system.
