Workhorse Scattering Instruments for Low Power Compact Accelerator Driven Neutron Sources

Abstract

We investigate the potential of neutron scattering instrumentation fed by a compact accelerator driven neutron source. Such a source can be built and operated easily at any large university. Reference designs of typical workhorse scattering instruments for small-angle neutron scattering, powder di ff ractometry and reflectometry are presented. The neutron flux at sample position and the instrument resolution have been calculated from the parameter design of a pulsed neutron source with 400 W average accelerator power. Instrument performances allow for reasonable scientific use even at this low power level.
