Journal ArticleDOI
Control of surface mobility for conformal deposition of Mo–Si multilayers on saw-tooth substrates
Dmitriy L. Voronov,Erik H. Anderson,Eric M. Gullikson,Farhad Salmassi,Tony Warwick,Valeriy V. Yashchuk,Howard A. Padmore +6 more
TL;DR: In this paper, the authors present an analysis of the roughening and smoothing processes during growth of Mo/Si multilayers deposited over a range of pressures of Ar sputtering gas on flat and saw-tooth substrates.
Journal ArticleDOI
Methodology for Optimal In Situ Alignment and Setting of Bendable Optics for Diffraction-Limited Focusing of Soft X-Rays
Daniel J. Merthe,Valeriy V. Yashchuk,Kenneth A. Goldberg,Martin Kunz,Nobumichi Tamura,Wayne R. McKinney,Nikolay A. Artemiev,Richard Celestre,Gregory Y. Morrison,Erik H. Anderson,Brian V. Smith,Edward E. Domning,Senajith Rekawa,Howard A. Padmore +13 more
TL;DR: In this paper, an optimal in situ configuration of bendable soft x-ray Kirkpatrick-Baez mirrors is presented. But the in situ methodology consists of a new technique for simultaneously setting the height and pitch angle of each mirror.

The Advanced Light Source elliptically polarizing undulator
Steve Marks,Christopher Cortopassi,J. DeVries,E. Hoyer,Robert Leinbach,Y. Minamihara,Howard A. Padmore,P. Pipersky,D. Plate,Ross Schlueter,Anthony Young +10 more
TL;DR: An elliptically polarizing undulator (EPU) for the Advanced Light Source (ALS) has been designed and is currently under construction as mentioned in this paper, which can produce variably polarized light of any ellipticity, including pure circular and linear.

Journal ArticleDOI
Synchrotron x-ray study of a low roughness and high efficiency K2CsSb photocathode during film growth
Junqi Xie,Marcel Demarteau,Robert Wagner,Susanne Schubert,Susanne Schubert,Mengjia Gaowei,Klaus Attenkofer,John J. Walsh,John Smedley,Jared Wong,Jun Feng,Howard A. Padmore,M. Ruiz-Oses,Zihao Ding,X. Liang,Erik Muller,Ilan Ben-Zvi,Ilan Ben-Zvi +17 more
TL;DR: Xie et al. as mentioned in this paper explored the evolution of roughness during sequential growth, and showed that deposition of multilayer structures consisting of very thin reacted layers results in an nm level smooth photocathode.
