“…10 Overall, the characterization of fluid-rock interactions, from the atomic scale to the macro-scale, in host rock formations is essential to understanding the kinetics and the total storage of CO 2 in these targeted formations. The combination of CENTAUR's capabilities with the neutron contrast-matching power will extend previous studies of pore accessibility, [11][12][13] induced pore deformation, [14][15][16][17] and gas behaviors in pores [17][18][19] at the nanoscale to atomicscale mineral structure. In addition, CENTAUR offers a wide range of sample environments, including an automatic in-line flow cell, temperature/pressure ramping, humidity control, strain, and shear.…”

CENTAUR will be the flagship general purpose small-angle neutron scattering (SANS) instrument for the Second Target Station of SNS. Based on an optimized and high-performance SANS instrument, it is capable of SANS/wide-angle neutron scattering and diffraction simultaneously filling the capability gap to cover structure scale from atomic scale to hundreds of nanometers for scientific needs ranging from polymers, biology, materials sciences, and quantum condensed matter. Additionally, with a high-speed chopper, it can be used as a direct geometry spectrometer to probe the dynamics in relatively large lengthscale structures as an inelastic SANS spectrometer. The technical details of the CENTAUR instrument are presented in this document. As the project progresses, the initial details are subject to change based on feedback.
