Journal ArticleDOI
High-Resolution X-Ray Photoemission Electron Microscopy at the Advanced Light Source
TL;DR: X-ray Photoemission Electron Microscopy (X-PEEM) is a full-field imaging technique where the sample is illuminated by an x-ray beam and the photoemitted electrons are imaged on a screen by means of an electron optics as mentioned in this paper.
Journal Article
Ultrafast magnetization dynamics studies using an x-ray streak camera
Andreas Bartelt,Alberto Comin,Jun Feng,J. Nasiatka,Howard A. Padmore,Andreas Scholl,Anthony Young +6 more
TL;DR: In this article, a new approach was described using x-ray magnetic circular dichroism to investigated emagnetization and magnetization switching processes in ferromagnetic thin films following an excitation by ultrashort 100-fs near-infrared laser pulses.
Proceedings ArticleDOI
Comprehensive Electron‐optical Characterization of an X‐ray Photoemission Electron Microscope
TL;DR: In this paper, a more comprehensive measurement of the PEEM-II instrument at beamline 7.3.1 at the Advanced Light Source (ALS) that examines the response of the instrument to a wide range of experimental conditions is presented.
Proceedings ArticleDOI
The VHF-Gun, the LBNL High-Brightness Electron Photo-Injector for MHz-Class Repetition-Rate Applications*

TL;DR: The VHF-Gun as discussed by the authors is a room-temperature RF gun designed for CW operation and high-brightness beam performance at LBNL. But the successful lower repetition-rate RF gun schemes cannot be scaled up to MHz rates.
Journal ArticleDOI
ALS renewal moves forward
Roger Falcone,Roger Falcone,B. Feinberg,Zahid Hussain,Janos Kirz,G.F. Krebs,Howard A. Padmore,David Robin,Art Robinson +8 more
TL;DR: The evolving strategic plan now in place aims to renew the ALS so it can address a new generation of fundamental questions about size dependent and dimensional-confinement phenomena at the nanoscale; correlation and complexity in physical, biological, and environmental systems; and temporal evolution, assembly, dynamics and ultrafast phenomena.
