1. Jefferson Lab Status & Outlook Hugh Montgomery Jefferson Lab Users Meeting, June 2014

2. Outline • Outline • Laboratory Highlights • 12 GeV Upgrade/Commissioning Progress • EIC • Summary

3. Laboratory Open House – May 17, 2014 ~6,000 visitors for JLab’s Open House May 17th

4. Safety FY2014 Statistics • Total Recordable Case • (TRC) Rate: • FY13: • Goal Rate 0.65 • Number: 9 cases • Actual Rate 0.93 • Days Away, Restricted or • Transferred (DART) Case Rate: • FY13: • Goal Rate 0.25 • Number: 7 cases • Actual Rate 0.73

5. Accelerating Science with GPUs Gauge Generation Benchmark • Before: Used CPU + GPU solver library for LQCD Analysis ( >95% work in solver ) • Gauge Generation uses solvers less - smaller gain from only accelerating solver • QDP-JIT layer moves entire calculation to GPU (+ we still use GPU solver library) • 2x-5x speedup over GPU solver library alone, 3.7x-11x speedup over CPU alone Strong (Hard) Scaling TOP 500 (#364) Supercomputer Data from: F. Winter (JLab), M. A. Clark (NVIDIA), B. Joo (JLab), R. Edwards (JLab) - Accepted for IPDPS’14 conference Applicable to leadership GPU systems such as DOE Titan (ORNL) and NSF Blue Waters (NCSA - University of Illinois) ASCR Computing Challenge Award 250M core hours: biggest ever in May 2014 (for only $750K!)

6. Physical Review Letter 111, 141803 (2013)

7. Measurement of the Parity-Violating Asymmetry in eD Deep Inelastic Scattering Nature 506, 67–70 (06 February 2014) The Jefferson Lab PVDIS Collaboration See also News & Views, Nature 506, 43–44 (06 February 2014) Longitudinally Polarized Electron Scattering from Unpolarized Deuterium (a [2C1u – C1d]+[2C2u – C2d]) • Provides a determination of the effective electron-quark weak coupling combination 2C2u – C2d that is five times more precise than before. • It is the first experiment to isolate, when combined with previous experiments like Q-weak, a non-zero C2q (at 95% confidence level). • This coupling describes how much of the mirror-symmetry breaking in the electron-quark weak interaction originates from the quarks' spin preference. The result provides a mass exclusion limit on the electron and quark compositeness and contact interactions of ~5 TeV. JLab PVDIS SLAC E122

8. Spin and Parity of the Λ(1405) Baryon • L(1405) is a well‐known hyperon (PDG Status: ****) • Spin-Parity, JP, has never been definitively measured • L(1405) created polarized via photoproduction in liquid hydrogen & detected in CLAS g + p → K+ + (1405), (1405) → + + p- (1405) → ++p- + → p +p0 • Isotropic decay of (1405) is consistent with spin • Polarization transfer to S+ direction reveals vs. • Quark model expectation confirmed • Higher spins are disfavored by the data and by theoretical expectations K.
