1^3-ARPES ultra high resolution photoemission station
This instrument is designed for angle-resolved photoelectron spectroscopy at the highest energy resolution and ultimately low sample temperatures. In this system, all contributors to experimental broadening – the resolution of both the excitation source and the electron energy analyzer as well as the sample temperature – have been reduced to ≤1 meV or their equivalent, yielding the name of the station: 1 meV x 1 meV x 1 K = 1^3.
