FY11 Budget and Consequences
• As yet there is no FY11 Budget– Senate Markup is -$100M wrt SC Pres. Request
• Specifics are not good for nuclear physics• Upgrade is not impacted
– House Markup is -$200M wrt SC Pres. Request• Details not available, but rumored to be bad.
• Continuing Resolution expected – “6 month” CR
• Will start running as planned, no advantage in delay• 12 GeV Project can ride 3 months OK
– “12 month” CR• Will need to curtail running• Major reduction in 12 GeV Project work, major delay
20
• Facilities: Resolve critical shortage and poor quality of space by constructing 278,000 sq ft and refurbishing 280,000 sq ft of work space; addressing safety and building code issues by updating outdated building systems; reducing deferred maintenance; and increasing energy efficiency.
– Technology Engineering Development Facility (TEDF) (SLI) provides 38% of new and 31% of refurbished space (CD-3A approved 3/26/10)
– CEBAF Center Expansion and Rehab (SLI 2016) ~ 34% of new space
– Lab’s $32M GPP investment provides ~28% of new space.
• Utilities: Replace/upgrade 20-40 year old site utilities to meet SC mission requirements by increasing cryogenics capability; increasing capacity and adding redundancy to the power distribution system; increasing cooling water capacity to meet mission requirements and replacing site cooling towers.
– Utility Infrastructure Modernization Project (SLI 2011)
• Communications: Upgrade 1960s subsurface communications systems with 627 miles of fiber optic cable and 42 miles of building computer cable (SLI 2011).

Strategy for the Future – Major Initiative ELectron Ion Collider (ELIC)
Further extension of electron – nucleus scattering physics
Developing the concept and the physics case and initial design of a future ELectron Ion Collider is essential to understand the future evolution of experimental nuclear physics in the U.S.A. and in the world. According to the 2007 NSAC Long Range Plan, “The ELIC would explore the new QCD frontier of strong color fields in nuclei and precisely image the gluons in the proton.” Goal is to develop the PHYSICS CASE for the next long range plan.
• The Vision for the program:
– The next generation of electroweak nuclear physics beyond CEBAF at 12 GeV would demand an Electron Ion Collider
• TJNAF will participate in the development of the physics case for the EIC
• TJNAF will engage in R&D to develop accelerator and detector technology enabling a very high luminosity, polarized Electron Ion Collider. An initial stage, a medium-energy electron-ion-collider, MEIC, would accommodate subsequent energy upgrade.
• MEIC would be a high-luminosity, polarized electron-ion collider which would use CEBAF as injector into an electron storage ring.
• MEIC would have a center-of-mass energy of 10-50 GeV and extremely high luminosity approaching 1x1035 cm-2s-1 . The high luminosity is crucial to probe unknown essential features of the proton landscape, such as the impact of spin-orbit correlations.
• The booster rings, electron collider ring, and ion collider ring are designed as a “figure 8”, a design directly aimed at spin physics opportunities.
• The range of nuclei considered includes polarized light ions (1H, 2H, and 3He) and medium to heavy nuclei (such as 12C, 40Ca, and 197Au).

Strategy for the Future - Major Initiative JLAMP and 4th Generation Light Sources
A Next Generation Photon Science Facility at Jefferson LabTJNAF has existing platforms with which it could demonstrate accelerator physics and technologies that address the needs of light source facilities as outlined in BESAC’s report “Directing Matter and Energy:Five Challenges for Science and the Imagination”. BESAC also delivered a position paper “Next Generation Photon Sources for Grand Challenges in Science and Energy” to SC. Two approaches to producing the required photons are identified: Free Electron Lasers and Energy Recovering Linacs. TJNAF has world class expertise in both technologies.
TJNAF received funding from BES to participate in R&D, focusing on cavity and cryomodule development ultimately to permit the demonstration of well controlled, pulse-to pulse repeatable, high duty factor X-ray bursts of femtoseconds duration and unprecedented brightness.
• The Vision for the program:Jefferson Lab has proposed to build a continuous wave, high average brightness, short pulse free electron laser operating in the VUV/soft X-ray regime named JLAMP (Jefferson Lab AMPlifier). JLAMP would produce photons at an average brightness exceeding that of the FLASH facility in Germany. JLAMP would provide a platform for:
– Ultrafast studies of emergent/correlated behavior in complex and nanomaterials related to energy and the environment, and with a strong user base of support as defined in recent BES reports.
– Research in accelerator concepts which have the potential for substantial reduction of costs and better performance for future large-scale light sources.
– Eventual participation in construction of a large scale next generation light source wherever it is built.
– Accelerator research and training relevant to DoD ONR.

Summary
PAC role is to provide advice with respect to the experimental nuclear physics program which is the core activity of the laboratory.
We are concurrently constructing the 12 GeV Upgrade Project.
We are also taking opportunities to upgrade the laboratory facilities and infrastructure.
Consequently there are challenges to balance the different activities within constrained resources.
(But we are getting support from Office of Nuclear Physics.)
We are also looking to the long term future of Jefferson Laboratory
