From the Director
We are now well into the FY2014 run, SPEAR3 continues to operate
exceptionally well, we have brought several beam lines back on line and are
aggressively pursuing a number of beam line construction and upgrade
However, I want to focus my message in this newsletter on user access issues
that have arisen this month due to SLAC’s recent implementation of a new
administrative system that has impacted a number of processes, including your
ability to get through the automated gates. This primarily impacts how quickly
we can bring users onto the experimental floor so you can get to work.
If you all would do the following BEFORE arriving at SLAC, you probably
won’t have any problems:
1. Complete all required training at least 48 hours before you arrive,
and bring a hard copy of the training certificates.
2. Make sure to review the check-in procedures since they may have changed since your
last visit. For example, SLAC Traffic Safety Training (Course #154) is a
recent requirement for gate access.
3. If you have training but are coming to SSRL for reasons other than
beam time, let URA know so we can make sure your badge is approved for
4. If you arrive without having done your training and run into
problems, call URA (650-926-2079) so we can help.
5. Reminder: unless you are certain that your badge will get you
through SLAC’s automated gates, stop first at the Security Office by the
We are working with the project team to get these problems resolved as soon
as possible. Please bear with us during this transition period.
Discovery of a Single Topological Dirac Fermion in the Strong
Inversion Asymmetric Compound BiTeCl – Contacts: Yulin
Chen, Stanford University, Oxford University and Zhi-Xun Shen, Stanford
Topological insulators comprise a new state of quantum matter that has been
predicted theoretically and realized experimentally in the past few years.
Strong inversion asymmetry in topological insulators could lead to many
interesting phenomena, such as pyroelectricity, intrinsic topological p-n
junctions and topological magneto-electric effects.
Researchers using Beam Line 5-4 at SSRL and Beam Line 10.0.1 at the
ALS have shown the compound BiTeCl to be the first topological insulator with a
strong inversion asymmetric crystal structure. Read more...
For the week beginning January 20, SPEAR3 was up 98.3% of the scheduled
time, the average uptime to date for our current experimental run is at 97%,
the MTBF is 52 hrs. The Average uptime for the injector is

Temporary Food Service Available during Construction of New
Cafeteria in Science and User Support Building
The SLAC Cafe, auditorium and visitor center have been closed and will be
replaced with a new Science and User Support Building (SUSB). During this
construction (2013-2015), temporary food service will be provided by the
Cardinal Chef Mobile Gourmet food trucks, 11am - 2pm in front of SLAC Building

AAAS Symposium: U.S. National User Facilities,
a Major Force for Discovery and Innovation (February 15, 2014)
The National User Facility Organization (NUFO) is partnering
with the DOE Office of Science and the National Science Foundation (NSF) to
sponsor a symposium at the 2014 AAAS meeting in Chicago. The symposium, America's
National User Facilities, a Major Force for Discovery and Innovation, will be
held 8:30-11:30 am on Saturday, February 15, 2 014 in the Hyatt Regency Hotel.
Please inform your colleagues and plan to participate to help raise awareness
about the benefits of using our facilities.
America's national scientific user facilities provide unique
capabilities, instrumentation, and expertise annually to approximately 50,000
scientists and engineers from academia, government, and industry. For many of
these individuals, a user facility is their laboratory—their primary
platform for experimental research—and they gain access to these unique
tools through peer-reviewed proposals. Much of the research is basic
(discovery) research, but the rich interdisciplinary environment promotes
interactions among scientists from diverse fields, institutional types, and
countries to facilitate the translation of these discovery findings into
solutions to real-world problems. This symposium will provide an overview of
the capabilities offered by these national facilities, and will highlight
outstanding recent examples of discovery and innovation stemming from work at
these user facilities, including the development of energy-harvesting
“solar shingles,” the discovery of the structure of key biological
molecules, the development of new drugs, and the discovery and the
contributions to our understanding of fundamental science.
The symposium will conclude with presentations by the major
federal sponsors of the user facilities with reserved time for discussion of
the policy challenges facing this key facet of America's scientific enterprise
now and into the future. The speakers are Eric Isaacs (Director Argonne
National Laboratory and soon-to-be Provost of The University of Chicago), Roger
Falcone (Director Advanced Light Source at LBNL), Stephen Wasserman (Senior
Research Fellow, Eli Lilly and Company), Eric Gawiser (Associate Professor,
Department of Physics and Astronomy, Rutgers University), Patricia Dehmer
(Deputy Director for Science Programs, Office of Science, DOE), and F. Fleming
Crim (Assistant Director for Mathematics and Physical Sciences, NSF)
Save the Date: SSRL School on Synchrotron X-ray
Scattering Techniques in Materials and Environmental Sciences, June 3-5,
The 7th SSRL SRXRS (Synchrotron Radiation-based X-ray
Scattering techniques) School will provide a practical users' guide to
planning and conducting scattering measurements at SSRL beam lines, and will
cover important techniques including small angle scattering, thin-film
scattering, powder diffraction, structure refinement and surface x-ray
scattering. The school will address topics that are not commonly included in
text books or class lectures, and typically obtained only through
on-the-experiment training. There will be hands-on sessions at SSRL beam lines
and session of diffraction theory and on data analysis. The school will also
cover new instrumentation at SSRL scattering beam lines. This year's
school, which will take place June 3-5, is organized by: Apurva Mehta, Stefan
Mannsfeld, Chris Tassone, and Mike Toney.

Inform Us of Publications
SSRL provides technical tools for world-leading science at
no charge for scientists who conduct non-proprietary research, with the
understanding that significant results are to be publicly disseminated.
Scientists must acknowledge use of the facility in presentations and
publications and must inform the facility of all publications, theses, awards,
patents and other forms of recognition resulting from research conducted fully
or partially at SSRL. These metrics of scientific achievements and productivity
are extremely important to the facility and to funding agencies. Please contact
us as results are about to be published so that we can work with you to more
broadly communicate your research. More information and acknowledgement
statements can be found on our publications page.
The Stanford Synchrotron Radiation Lightsource (SSRL) is a third-generation
