Submit Comments, Suggestions, and Ideas for MBA Lattice Workshop

October 21-22
Advanced Photon Source
Argonne National Lab

The Advanced Photon Source Upgrade is focused on delivering a powerful, versatile facility for science using high-brightness, high-energy X-rays. At APS, and around the light source community, scientists have been developing storage ring designs that push closer to the ultimate diffraction limit for X-ray sources. A recent report by the Basic Energy Sciences Advisory Committee, which advises the Director of the U.S. Department of Energy Office of Science, has recommended leveraging such "multi-bend achromat" (MBA) technology to advance the science performed by the U.S. synchrotron radiation user community. This emerging technology could provide orders-of-magnitude improvement in brightness and coherent flux, enabling transformational advances in imaging, in studies of dynamics, and in nanometer-resolution probes utilizing the full array of powerful X–ray contrast modes, from diffraction to spectroscopy to resonant inelastic X-ray scattering.

This workshop is being held to explore the opportunities that could be provided if MBA technology is implemented within the ongoing APS Upgrade project. Specifically, this workshop seeks to accomplish the following goals:

  1. Inform the APS community concerning the properties of an MBA low-emittance lattice being considered in the APS Upgrade.
  2. Gather input on the new science opportunities offered by such a source.
  3. Address how our current suite of beamlines map onto these envisioned science opportunities, and what new capabilities are needed.
  4. Explore the technical advances in optics, detectors, and undulators that are required to realize these science opportunities.
  5. Identify areas that require R&D efforts to achieve the ultimate performance from an MBA x-ray source.

Input from the user community and facility staff is an essential component of making the best decisions in defining an enhanced MBA lattice, undulators, and experimental facilities that enable the best science from the APS.

The workshop will begin on Monday, October 21, 2013 at Argonne National Laboratory Advanced Photon Source and conclude on Tuesday, October 22, 2013.

The workshop will consist of a plenary session and breakout sessions exploring these seven areas:

  • Scanning Probe Imaging
  • Coherent Diffraction and Phase Contrast Imaging, XPCS
  • Timing and Dynamics
  • Interface and Single Crystal Diffraction
  • Structural and High Energy Scattering, SAXS
  • Spectroscopy and Inelastic Scattering
  • Macromolecular Crystallography

All APS users and APS staff are invited to attend this workshop. Registration (at no-cost) is required for all attendees to the Workshop. Registration for the workshop can be completed at
