Time- and angle resolved photoelectron spectroscopy (trARPES) using a momentum microscope and femtosecond extreme ultra-violet (XUV) pulses offers a unique, full in-plane momentum and energy resolved picture of the transient, excited state band structure of many crystalline materials. In this training module, we offer an introduction into the theoretical and experimental aspects of the method. This is complemented by some hands-on experience in our trARPES lab, as well as some introduction into the analysis of 4D momentum microscopy data.
