Here we report on a novel High Harmonic Generation (HHG) light source designed for space charge free ultrafast photoelectron spectroscopy (PES) on solids. The ultimate overall energy resolution achieved on a polycrystalline Au sample is ~22 meV at 40 K. These results have been obtained at a photon energy of 16.9 eV with a pulse bandwidth of ~19 meV, by varying, up to 200 kHz, the photon pulses repetition rate and the photon fluence on the sample. These features set a new benchmark for tunable…

High resolution time- and angle-resolved photoemission spectroscopy with 11 eV laser pulses.

TLDR
A novel 11 eV tr-ARPES setup is presented that generates a flux of 5 × 1010 photons/s and achieves an unprecedented energy resolution of 16 meV and is demonstrated by simultaneously capturing the energy and momentum resolved dynamics in two well-separated momentum space regions of a charge density wave material ErTe3.

A quantitative comparison of time-of-flight momentum microscopes and hemispherical analyzers for time-resolved ARPES experiments

Time-of-flight-based momentum microscopy has a growing presence in photoemission studies, as it enables parallel energy- and momentum-resolved acquisition of the full photoelectron distribution.

Ultrafast extreme ultraviolet photoemission without space charge

TLDR
The high photocurrent, lack of strong space charge distortions of the photoelectron spectra, and excellent isolation of individual harmonic orders allow the time-resolved XUV photoemission experiments in a qualitatively new regime to be observed.

High-flux ultrafast extreme-ultraviolet photoemission spectroscopy at 18.4 MHz pulse repetition rate

TLDR
The measurement time reduction and the photon energy scalability render this technology viable for next-generation, high-repetition-rate, multidimensional attosecond metrology, and a large count rate improvement over state-of-the-art attose Cond setups under identical space charge conditions.
