Journal ArticleDOI
Experimental characterization of als undulator radiation
P.A. Heimann,D. A. Mossessian,A. Warwick,C. Wang,S. Marks,Howard A. Padmore,B. Kincaid,Eric M. Gullikson +7 more
TL;DR: In this article, the radiation from the 5 cm period undulator at the Advanced Light Source (ALS) has been characterized using a transmission grating spectrometer using a spectral and angular distribution of radiation.
Journal ArticleDOI
A new separator design for aberration corrected photoemission electron microscopes
TL;DR: In this paper, a separate function design that is simple to construct and fully adjustable, which allows more relaxed tolerances on alignment errors and power supply ripples is presented, which gives as good, if not better, a performance as the existing design.
Proceedings ArticleDOI
An experimental apparatus for diffraction-limited soft x-ray nano-focusing
Daniel J. Merthe,Kenneth A. Goldberg,Valeriy V. Yashchuk,Sheng Yuan,Wayne R. McKinney,Richard Celestre,Iacopo Mochi,James Macdougall,Gregory Y. Morrison,Senajith B. Rakawa,Erik H. Anderson,Brian V. Smith,Edward E. Domning,Tony Warwick,Howard A. Padmore +14 more
TL;DR: In this paper, a bendable Kirkpatrick-Baez (KB) mirror was used to achieve a focused, FWHM spot size of 150 nm, with 1 nm (1.24 keV) photons at the Advanced Light Source (ALS) beamline 5.3.
Journal ArticleDOI
Design and performance of the ALS diagnostic beamline
TL;DR: In this paper, the design and operation of an imaging beamline at the Advanced Light Source used for providing diagnostic information on the electron beam for the accelerator and experimental groups is described.
Proceedings ArticleDOI
Real-time data-intensive computing
