Characterization and suppression of background light shifts in an optical lattice clock

Autor: Fasano, R. J., Chen, Y. J., McGrew, W. F., Brand, W. J., Fox, R. W., Ludlow, A. D.

Experiments involving optical traps often require careful control of the ac Stark shifts induced by strong confining light fields. By carefully balancing light shifts between two atomic states of interest, optical traps at the magic wavelength have b

Sparse identification of multiphase turbulence closures for coupled fluid--particle flows

Autor: Beetham, S., Fox, R. O., Capecelatro, J.

In this work, model closures of the multiphase Reynolds-Average Navier-Stokes (RANS) equations are developed for homogeneous, fully-developed gas--particle flows. To date, the majority of RANS closures are based on extensions of single-phase turbulen

Development of a novel MPGD-based drift chamber for the NSCL/FRIB S800 spectrometer

Autor: Cortesi, M., Pereira, J., Bazin, D., Ayyad, Y., Cerizza, G., Fox, R., Zegers, R. G. T.

The performance of a novel tracking detector developed for the focal plane of the NSCL/FRIB S800 magnetic spectrometer is presented. The detector comprises a large-area drift chamber equipped with a hybrid Micro-Pattern Gaseous Detector (MPGD)-based
