摘要：

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. Published by Elsevier B.V.
