## National SynchrotronLight Source

- First Dedicated Second Generation Synchrotron
*and only remaining second generation DOE synchrotron!*
- Designed in the 1970’s
- Operating Since 1982
- Continually updated over the years
- - Brightness has improved more than 100,000 fold
*However*
- - The brightness has reached its theoretical limit
- - Only a small number of insertion devices are possible

**Restricted Capabilities of present NSLS limit the productivity and impact of its large user community**

**1990**

**2000**

- Improvement in Electron Beam Emittance

## The Mission Need for NSLS-II

- Major studies by BESAC, BES, and the National Nanotechnology Initiative have reassessed the research and the scientific tools needed to advance energy technologies.
- A common conclusion is that the development of nanoscale materials – as well as the methods to characterize, manipulate and assemble them – is critical for the development of future energy technologies.
- The remarkable tools that were developed over the past 30 years for visualizing the nanoworld – in particular, the synchrotron radiation light sources – helped launch the nanorevolution; ; however, none of today’s light sources (anywhere in the world) were designed to probe materials with 1 nanometer spatial resolution and with 0.1 meV energy resolution (equivalent to ~1 K).

**The Mission Need for NSLS-****II**

***“******Light sources with even more advanced capabilities than the best available today are needed to address the challenges put forward in these and other reports.”***

- A highly optimized x-ray synchrotron delivering:
- extremely high brightness and flux;
- exceptional beam stability; and
- a suite of advanced instruments, optics, and detectors that capitalize on these special capabilities.
- Together, these enable:
-  ~ 1 nm spatial resolution,
-  ~ 0.1 meV energy resolution, and
-  single atom sensitivity.

**High Level Description of NSLS-****II**

## What Research will NSLS-II Uniquely Enable? 

***Opportunities for Catalysis***
*** ******in the 21******st****** Century***

**University of Texas**

- The “nanoscale” covers the length range from 1 to 100 nm, but the low end of this scale is particularly important for many fundamental studies.
- Research at the NSLS-II will focus on some of the most important challenges at the lower end of the nanoscale size range, including:
*the correlation between ****nanoscale structure ****and materials properties and functions; *
*the mechanisms of molecular ****self-assembly****, which produces exquisite molecular structures in both the living and nonliving worlds; and *
*the science of ****emergent behavior****, which arises from cooperative behavior of individual components of a system.*

**What Research will NSLS-II Uniquely Enable?**** **

- Molecular Electronics

**Notes:**
1) Nanoscale structure and function – carbon nanotube and molecular electronics for lower power and faster electronics that scale beyond silicon
2) Self assembly – all walked along the beach and marvelled at the complex and intricate structure of shells – these are examples of self assembly – wouldn’t it be wonderful if we could mimic nature and learn how to initiate and control the self assembly of constituent materials into new complex hierarchical structures – this could be the basis for a completely new approach to maufacturing
3) emergent behavior – flocking of birds
