Title: The Center for Advanced Microstructures and Devices (CAMD): New Opportunities and New Facilities

Abstract

This paper presents the status and the operation conditions of the 1.3 GeV storage ring at the Center for Advanced Microstructures and Devices (CAMD). An overview of existing beamlines with their relevant parameters is given and four beamlines that came into operation over the last two years are discussed in some detail.

  • A new tomography beamline has been built and commissioned at the 7 T wiggler of the CAMD storage ring. This beamline is equipped with two monochromators that can be used interchangeably for X-ray absorption spectroscopy or high resolution X-ray tomography, at best 2-3 {mu}m pixel size. The high-flux double multilayer-mirror monochromator (W-B4C multilayers) can be used in the energy range from 6 to 35 keV with a resolution ({delta}E/E ) between 0.01-0.03. The second is a channel-cut Si(311)-crystal monochromator with a range of 15 to 36 keV and resolution of ca. 10-4, this is not yet tested. Tomography has themore » potential for high-throughput materials analysis; however, there are some significant obstacles to be overcome in the areas of data acquisition, reconstruction, visualization and analysis. Data acquisition is facilitated by the multilayer monochromator as this provides high photon flux, thus reducing measurement time. At the beamline, Matlab(c) routines provide simple x,y,z fly-throughs of the sample. Off-beamline processing with Amira(c) can yield more sophisticated inspection of the sample. Standard data acquisition based on fixed angle increments is not optimal, however, new patterns based on Greek golden ratio angle increments offer faster convergence to a high signal-to-noise-ratio image. The image reconstruction has traditionally been done by back-projection reconstruction. In this presentation we will show first results from samples studied at the new beamline.« less
  • The x-ray lithography and micromachining facility at CAMD is described. It consists of four dedicated beamlines and exposure stations using the synchrotron radiation delivered by the CAMD storage ring and 230 m{sup 2} of fully equipped clean room. The scientific and engineering activities exemplified by results of current studies are reported. {copyright} {ital 1996 American Institute of Physics.}
  • The new synchrotron-radiation facility, Center for Advanced Microstructures and Devices, at Louisiana State University is described with regard to the status of installation of the storage ring, implementation of the various programs, and construction of the first beamlines.
  • The LSU Center for Advanced Microstructures and Devices (CAMD) is a DOE-funded materials science and engineering laboratory which will include a normal-conducting compact electron storage ring optimized for the production of soft x rays. The focus of CAMD is the fundamental study of processing and analysis technologies---including x-ray lithography---important to microstructure fabrication and electronic device development. Design details of the storage ring, which is being acquired commercially, are presented in this article.
  • Often radioactive waste disposal operations are temporary but still need durable, secure shelters and storage facilities. The ideal enclosure would be inexpensive, durable for extended projects, suitable for rapid erection with or without permanent footings, and weathertight and easily moved. Tensioned fabric structure technology comes close to meeting all requirements. This article discusses this technology in terms of how it could be used at for example Rocky Flats. The background of modern tention fabric structures is discussed along with fabric structures and building codes, characteristics, and design considerations. 4 figs.
