## Key Points of the Charge

- the extent to which the proposed facility would answer the most important scientific questions;
- whether there are other ways or other facilities that would be able to answer these questions;
- whether the facility would contribute to many or few areas of research;
- whether construction of the facility will create new synergies within a field or among fields of research;
- what level of demand exists within the scientific community for the facility.

**Categorize as “absolutely central,” “important,” and “don’t know enough yet,” according to the potential importance of their contribution.  **

_**Importance of the science**_

_**Readiness of the facility**__ _

- whether the concept of the facility has been formally studied in any way;
- the level of confidence that the technical challenges involved in building the facility can be met; the sufficiency of R&D performed to-date to assure technical feasibility of the facility; the extent to which the cost to build and operate the facility is understood.

**Categorize according to their readiness as “ready to initiate construction,” “significant scientific/engineering challenges to resolve before initiating construction,” and “mission and technical requirements not yet fully defined.”  **

## Light Sources

- Upgrade Initiative
- Advanced Light Source (ALS)
- Advanced Photon Source (APS)
- National Synchrotron Light Source (NSLS)
- New facilities
- Linac Coherent Light Source (LCLS)
- LCLS II
- “Green-field” X-ray Free Electron Laser (XFEL)
- Linac based Ultrafast X-ray source (LUX)
- Thomas Jefferson Lab Infrared FEL
- Coherent Infrared Center at the ALS (CIRCE)
- APS super storage ring
- NSLS third generation ring

## Light Source Upgrade Initiative

- The four DoE Light Sources are central to our nation’s research enterprise
- Urgent upgrades required to optimize scientific productivity and maintain competitiveness
-    We recommend that DoE aggressively pursue an upgrade initiative, coordinated among the four light sources.

## Linac Coherent Light Source

- Essential for exploring future science using intense femtosecond coherent X-ray beams
- DoE Critical Decision 0 and 1 have been approved

- Recommend continued strong support

## National Synchrotron Light Source

- One of the world’s most scientifically productive x-ray sources with ~ 4000 users.
- Proposed - 3rd generation ring, SC LINAC, HGHG FEL and upgraded VUV ring.

- Recognizing  the continued need for 3rd
- generation x-ray sources, we recommend that NSLS and BES formulate a plan for a 3rd gen. ring.

## Advanced Photon Source

- One of the world’s premier hard x-ray sources
- Phase I & II - upgrades essential to optimize scientific output and maintain international competitiveness.
- Phase III & IV – implementing ‘super storage ring’ and advanced instrumentation.

-  Strongly support upgrade of facility beamline
-     and source optimization (phase I and II)
-  Support long-term development of III and IV

## LCLS II and “Greenfield” XFEL

- XFEL opens up new scientific horizons
- 20 year vision for full-fledged XFEL-based User-facilities.
- technical challenges include e-gun, detector, e-beam stability, etc.
- LCLS progress towards XFEL feasibility is critical

- R&D on XFEL must proceed with emphasis
- on elucidating future scientific opportunities.

## Terahertz Radiation Facilities

- Jefferson Lab Terahertz FEL/ERL
- Coherent IR CEnter (CIRCE) at ALS
- low-energy spectroscopy is critical to understanding collective dynamics
- potentially large user community

- National scientific agenda and User
- needs should be better developed.

## LINAC-based Ultra-fast X-ray (LUX) Facility at LBNL

- Innovative proposal for ultra-fast VUV/X-ray facility offering exciting new scientific opportunities
- technical challenges include HGHG cascades essential for VUV production.

- Recommend development of National scientific
- community is essential as well as R&D to
- address technical challenges

## Neutron Scattering Facilities

- SNS Power upgrade
- SNS Long wavelength target station
- Second cold source for HFIR
- Accelerator based continuous neutron source

## Spallation Neutron Source (SNS) Power Upgrade

- SNS will be the world’s premier neutron source.
- 10% additional investment gains 2-3 times in scientific productivity.
- technical challenges include target modifications – ready for CD-0.

- Strongly recommend DOE support for this project

## Spallation Neutron Source (SNS) Long Wavelength Target Station

- Long wavelength second target station optimized, e.g., for SANS, reflectivity, inelastic scattering
- Scientific imperative – soft condensed matter, magnetism, nano-materials, etc.
- No foreseeable technical challenges, uses existing infrastructure.

- Recommend initial planning begin.

## Other Facilities

- Transmission Electron Aberration-Corrected Microscope (TEAM)
- AMES Plant Metabolomics Resource Facility
- Complex Interfacial Catalysis Facility

## Transmission Electron-Aberration Corrected Microscope (TEAM)

-  Network of linked electron microscopes capable of atomic resolution 3D imaging - first one to be at LBNL
-  Has advantage of large focal length
-  Technology demonstrated
-  Central to DoE mission.

- We recommend that this project be funded, and that the principals work closely with supplier/instrument community for development and construction.

## AMES Plant Metabolomics Resource Facility

- Leading researchers and important science
- Encourages synergy between Ames Laboratory and Iowa State University

- Research should be supported. It is premature to view it as a national facility.

## Complex Interfacial Catalysis Facility

- Proposed user facility for Catalysis research
- Catalysis is a key piece of DOEs portfolio

- Subcommittee recommends that any decision
- on a catalysis facility such as this needs to be
- reviewed in the context of competing proposals

## Cross Cutting Issues

- Detectors and other instrumentation
- Electron gun development
- Superconducting short period undulators
- Energy recovery LINAC (ERL) development
