Key Points of the Charge
Importance of the science

• 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 dont know enough yet, according to the
potential importance of their contribution.
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 RD 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.

7
Light Source Upgrade Initiative

• The four DoE Light Sources are central to our
  nations 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.

8
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
9
National Synchrotron Light Source

• One of the worlds 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.
10
Advanced Photon Source

• One of the worlds 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

11
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

RD on XFEL must proceed with emphasis on
elucidating future scientific opportunities.
12
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.
13
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 RD
to address technical challenges
14
Neutron Scattering Facilities

  ready for CD-0.

Strongly recommend DOE support for this project
16
Spallation Neutron Source (SNS) Long Wavelength
Target Station

• Long wavelength second target station optimized,
  e.g., for SANS, reflectivity, inelastic
  scattering

  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.
19
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.
20
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
