TL;DR: Experiments in which metastable xenon atoms were ionized with intense 7-micrometer laser pulses from a free-electron laser recorded holographic structures that record underlying electron dynamics on a sublaser-cycle time scale, enabling photoelectron spectroscopy with a time resolution higher than the duration of the ionizing pulse.

TL;DR: This Letter reports photoionization microscopy experiments where this nodal structure of the Stark Hamiltonian is directly observed, providing a validation of theoretical predictions that have been made over the last three decades.

TL;DR: High-resolution holograms for the ionization of metastable xenon atoms by 7-16 μm light from the FELICE free electron laser are presented and compared to semiclassical calculations that provide analytical insight.

TL;DR: In this paper, a user's guide to a new technique for biological and bio-medical research is presented, where the benefits of accurate mass analysis, high mass resolving power, additional separation strategies and multimodal three-dimensional data reconstruction algorithms are discussed to provide the reader with an insight in the current technological advances and the potential of mass spectrometry for biomedical research.

TL;DR: A new type of position-sensitive detector based on a chevron microchannel plate stack in combination with a 512 × 512 complementary metal-oxide-semiconductor based pixel detector is coupled to an ion microscope to improve spatial resolution and acquisition speed in mass spectrometry imaging.
