Increased scientific interest in 2D materials, heterostructures, and operational devices that incorporate quantum materials necessitates measurement techniques capable to isolating clear signals from such small and complex systems. Here, we present our new spatially resolved ARPES beamline at the ASTRID2 synchrotron, SGM4, where a <4 μm beam spot is produced using an elliptical capillary optic. We demonstrate the capability of this beamline using nanoARPES measurements on several example systems, such as in-operando ARPES from a 2D device.
