12 GeV Upgrade Project

Upgrade is designed to build on existing facility: vast majority of accelerator and experimental equipment have continued use

New Hall

Add arc

Enhanced capabilitiesin existing Halls

Add 5 cryomodules

Add 5 cryomodules

20 cryomodules

20 cryomodules

Scope of the project includes: •Doubling the accelerator beam energy•New experimental Hall and beamline•Upgrades to existing Experimental Halls

Maintain capability to deliver lower pass beam energies:

2.2, 4.4, 6.6….

Upgrade arc magnets and supplies

CHL upgrade

Hall D Status – July 2011

Ready For Equipment (RFE) Dec. 28, 2010


Installation


RF ZonesInstallation and testing of new RF power for the new cryomodules:SL24 fully installed, SL24 and SL23 in progress….and……


• Hall D Solenoid refurbishment is one month ahead of schedule.

Hall D Solenoid

• Coil #1 tested at 1200A





6MSD – Highlights

• Very Good Progress

• Magnet rework and reinstallation went very well Rework, reinstallation in west arc, installation of Arc 10 done “stretch” goal (rework Arc 7, 9 and added Arc 5) in East Arc done

• RF installation, LCW, FEL, and major scope of work on track so far• Civil work proceeding apace

• Halls making progress

• After delays as a result of microphonics measurements and analysis,revised plan for installation and testing of C100-1 installed, cold and in test. C100-2 being worked.

• Steering processes, teams and tools (integrated schedule) put in place for the 6MSD worked very well.


Computational Nuclear Physics

Perform state-of-the-art Lattice QCD calculations with particular reference to the Experimental Program

Lattice calculation of the low-lying meson and baryon spectrum, with the contribution of multi-hadron states included, at a pion mass of 230 MeV

Operate the JLab portion of the LQCD National Computing Resources in support of the USQCD Collaboration

Increase national Lattice QCD capability, as laid out under FY10-14 LQCD-ext project execution plan. Present successful case to USQCD Executive Committee for JLab to be the location.

Major Events/Accomplishments• Held an internal machine design

review (Sep. 15 & 16, 2010)

• Held an internal Workshop on the choice of RF SRF/750 MHz

• Held an internal MEIC Ion Complex Design Workshop (Jan. 29 & 30, 2011)

• Reported the MEIC machine design in the EICAC Meeting (April 10, 2011)

• Received a grant ($900K) from DOE/NP for MEIC R&D (Nov. 2010)

• Planning for 2nd MEIC Internal Accelerator Design Review and 1st Cost Review this Fall

Accelerator Team’s Roadmap Toward the Next NSAC LRP


EICAC Recommendations

Three recommendations on accelerator• In future presentations each facility clarifies what is being considered as part of

their baseline proposal, and separately what the ultimate upgrade performance might be

• To perform start-to-end simulation of the BNL ERL design and to have it reviewed by ERL beam dynamics experts… suggest that BNL develop a fall-back electron cooling design

• To conduct technical design reviews and cost estimates for both proposed facilities with enough similarity so that credible conclusions can be drawn on technical realization, cost and schedule; perhaps this could be done by establishing a joint technical review committee

and one on detector• Reemphasizes its previous recommendation on the importance and the urgency

of simulation work to understand the relation between detector performance and quality of physics results, in order to better understand the trade-off between detector resolutions and acceptances on the one hand, and luminosity, polarization and beam energies on the other


Electron Ion Collider

• Jefferson Lab Community Workshops

• INT 10 week Workshop

– Workshop Report – available

• Considerable progress on MEIC Design

• Detector R&D Funding from BNL

• Electron Ion Collider Advisory Committee Meeting at Jefferson Lab adjacent to DIS2011

• Plan, Writing Team, for EIC White Paper

– Target later 2011


UV Lasing at JLab FEL

February 28, 2011: Jefferson Lab's Free-Electron Laser delivered its first beam of laser light from the ultraviolet FEL into an experimental lab.


JLab FEL VUV Opportunities


Initial Science with JLab VUV FEL

1. Atom Trap Trace Analysis (ATTA).

- 81Kr dating (229,000 yrs compared to 14C -5730 yrs)- 85Kr detection (nuclear security)

2. Combustion dynamics.

- Time-resolve intermediate chemical states- Advanced fuels and engines higher efficiency and

reduced emissions

3. Electronic structure of correlated materials.

- Electron quantum structure via photoemission- Novel materials, e.g., high Tc superconductors


Photon Science Activities – 2011 Timeline

• Feb. 28 – VUV from FEL

• March – CD-0 for NGLS

• April 27 – visit from Center for Innovative Technology (Va. economic development org)

• May 9 – Director’s Review of VUV pilot program

• May 23 – Annual Lab Plan Presentation to DOE

• June 17 – Va. Univ. representatives meet at JLab

• July 6 – visit U. Va.

• July 20 – Va. Secy of Education visit


Budget Issues• FY11

– Nuclear Physics provided excellent support– 12 GeV Upgrade at $36M– TEDF Project fully funded– UIM Project moved out to 2013 (if it survives)

• FY12 House EW Markup– NP needed increase to support 12 GeV and FRIB– NP $53 M less than request– House EW Markup 12 GeV $40M ($66M req) in table– FRIB $24M ($30M req) in language– TEDF OK, UIM in out years

• DNP plus Lab Directors – Bob Redwine + KG, HM, SA signed one page position paper– Visit to staffers on July 11


Concerns

• Short Term Budget

• End Game in Physics of 12 GeV Project

• Startup/Commissioning of 12 GeV Program

• Longer Term Schedule Overcommitment
