NSF NeXUS Facility Achieves Major Milestones; Two Experimental End Stations Installed

Karen Keller General News

The NSF NeXUS Facility is beginning to take shape! Fall of 2021 brought a number of significant milestones to the project, including the delivery and installation of two experimental end stations.

STM End Station

Following the successful renovation of the laser lab and installation of an optical table system to support multiple beamlines (both completed this summer), the next phase of construction turns to the NeXUS system itself. First to arrive was the Scanning Tunneling Microscopy (STM) End Station. Installed in September, the STM End Station will be coupled to a beamline that will generate tunable extreme ultraviolet (XUV) light in order to combine element-specific spectroscopic contrast with ultrafast time resolution and atomic-scale spatial resolution. This enables studies of temporally and spatially resolved charge and spin dynamics at surfaces.

ARPES End Station

In October, the Time- and Angle-Resolved Photoemission Spectroscopy (TR-ARPES) End Station was delivered; installation is now underway. Coupled to a beamline that generates high repetition-rate extreme ultraviolet (XUV) pulses with a spectral resolution below 30 meV, the ARPES End Station enables time- and angle-resolved photoemission measurements to investigate dynamic processes in materials including electron relaxation, spin relaxation, evolution of spin-momentum locked states, and dynamics of correlated states.

We are excited to share the facility’s progress! Stay tuned for more updates.
