Workshop: Xray Absorption Spectroscopy at NSLS-II (Wednesday January 16, 2008)

The NSLS-II project recognizes that X-ray Absorption Spectroscopy is one of the core competencies of the NSLS community. Consequently, one of the six NSLS-II Project Beamlines will be an XAS facility. This will be one of the first operational beamlines and will be built as part of the NSLS-II construction project.

This new XAS beamline is very exciting. It will be built on a Damping Wiggler source, which will provide exceptional flux over a very broad energy range. Using a collimating mirror, a toroidal focusing mirror, and a double crystal monochromator, we anticipate being able to deliver almost 10¹⁴ photons/second in a 200 micron spot at 10 keV, with that flux dropping only to 10¹² photons/second at 90 keV.

At this workshop, we will discuss the scientific and technical needs of the various scientific disciplines that use XAS and we will speculate on how this extraordinary new source will create opportunities for new science currently unavailable at NSLS or, indeed, any other XAS beamline in the world.

We invite the members of the NSLS XAS community to attend this workshop, to join in our discussions of the scientific requirements of our community, and to help us define the scientific and technical mission of this new facility.

The primary goal of this workshop is to establishment a Beamline Advisory Team (BAT) to be composed of members of the NSLS XAS community. The BAT will provide oversight to the design, planning, development, and construction of the damping wiggler XAS beamline and to help assure that the beamline will meet its scientific potential. The first job of the BAT will be to draft a Letter of Intent (LOI) outlining the beamline's scientific and technical mission. With the LOI, design and construction can begin.

Questions and Answers

Who is on the BAT?

• See /BAT. Several disciplines (chemical and energy, environmental, materials, bioscience) which use XAS extensively are represented, along with a chair and a member to oversee optics and instrumentation issues. If you are interested in the work of the BAT, please contact Bruce <bravel AT SPAM SUPPRESSION bnl DOT gov>.

What is the format of the Letter of Intent

• We have limited information so far. Here is what we have. Drafts and the final version of the LOI will be posted here eventually.

What's up with those obfuscated email addresses?

• If you are not logged into the http://xafs.org system, email addresses are obfuscated to hinder harvest robots. Remove the words SPAM SUPPRESSION, convert AT to the @ symbol, and DOT to the . symbol to recover the real email addresses.
