Abstract

The upgraded MLNSC target system is designed to be a split target with two tiers of moderators. The original suite of four moderators serving twelve flight paths has been optimized and an additional pair of moderators, one water and one LH₂, have been added in a new upper moderator tier serving four additional flight paths. The upper moderators are partially coupled and viewed in backscattering geometry, as opposed to the decoupled moderators in the existing MLNSC target system, which are viewed in transmission geometry. Fabrication of this new target system is currently in progress and installation is expected in 1998. The neutronic performance of the target system is presented in the form of time and energy spectra for each of the planned moderators with comparisons to the existing MLNSC moderators. Results of upper target length and reflector materials studies are presented as examples of the work completed in support of the new target system.
