1 JLab Perspective on Hall A Rolf EntRequest: news of the lab with a perspective on Hall A. plans for sustainable multi-hall operations of CEBAF and prospects for full energy capability  I assume Arne will cover, but I will add some perspective on scheduling recent progress in the JLEIC project and perspectives for realization. Rolf Ent Note: I took many slides from Mont/Bob … but gave it my own spin by adding some Hall A Collaboration Meeting Jefferson Lab - January 18, 2017

2 ERR (Experiment Readiness Review) in a NutshellIf your experiment includes one-of-a-kind equipment with potential novel safety implications (examples are SC magnets, tritium or high-power cryogenic targets) it requires a first-phase ERR for this equipment at the design stage. If your experiment requires items in the category above and/or equipment beyond the declared base equipment (examples are new detector technologies, new beam lines, new spectrometers), it requires a second-phase ERR before scheduling can be requested. Always check if you need a second-phase ERR well in advance of considering a request for scheduling. If your experiment only includes base equipment (as declared by the Deputy AD) and only in operation modes already executed, or only additional equipment that is a direct clone of base equipment, it only needs a third-phase ERR. 2

7 Future Projects MOLLER experiment (Possible MIE – FY17-20)– Standard Model Test – DOE science review (September 2014) – strong endorsement – Director’s review held December 15-16, 2016 Technical, cost & schedule Report due in mid January – Still hope for FY18 start SoLID – CLEO Solenoid  – Chinese collaboration – Director’s review (Feb. 2015)  new pre-CDR almost complete – Collaboration briefing to DOE-NP (Nov. 2015)

8 FY17 Budget Nominally, first year of full operations in 12 GeV-era and Operations budget should have increased correspondingly. President’s Budget (NP = $636M) up 3% JLab Ops up $5.5M; but insufficient for full operation Major increases in isotope program (+$8M) and RHIC (+$7.5M) Senate Mark: $636M Language for FRIB construction and RHIC ops House Mark: $620M Language for FRIB construction, RHIC ops, and CEBAF ops No Federal Budget yet: Continuing Resolution (CR) until April 28. Held to FY16 level - NP $15.4M below Pres. Budget JLab $5.5M below Pres. Budget NP=DOE Office of Nuclear Physics

9 FY17 Planning Anticipate considerable uncertainty in transition between Administrations NP additional Ops support? If a full year CR, NP has substantial shortfall FY16 CR Budget level: Major impact on non-labor spending (travel, hardware, contract labor, etc.) Reduced Weeks of Accelerator Operation: Pres Budget = 23 weeks FY16 Level = 16 weeks Workforce: New/replacement hires limited to critical needs In extremis, forced vacations and furloughs would be considered Reduction in force not anticipated U.S. has made a major investment in CEBAF. Laboratory has a clear mission, nuclear physics and accelerator technology, which is supported by DOE. We will work to mitigate negative effects of budget constraints on all aspects of the program, especially the workforce.

12 Priorities Folded into Scheduling12 GeV Project Priorities Scientific Priorities – High Impact and/or Timeliness Funding Agency Commitments such as DOE/NP Capital Equipment Commitments (SBS, BRICH, DDIRC, etc.) DOE/HEP Commitment (HPS) NSF/MRI Funded Equipment (e.g., PRad, Hall C SHMS Detectors, NPS) International Funded Equipment (e.g., BRICH) Pragmatic Reasons such as Safety Issues – ALARA (like use HRS not BigBite with Tritium target experiments, Tritium only one year on site) Scientific Priorities – Science Rating or Verify Operational Requirements (like new beam requirements, new detector commissioning, etc.) What is ready and “fits” into schedule Installation times required Likelihood to get science results out fast Impact on Young Scientists and/or PhD Students Can only run 3 out of 4 Halls together (up to Fall 2018?) What could run beyond May 6 Power Meter Readout

13 Operations Constraints – some examplesHalls B and C are gearing up for 12-GeV pre-ops KPP demonstration  they must get priority in accelerator operations. We can run with a Hall multiplicity of 3.0 only, out of 4 Halls, until Accelerator Operations has fully commissioned potential 4-Hall Beam Delivery (Fall 2018)  BUT, to get to a Hall multiplicity of 3.0 with a versatile and reliable machine will take some effort  see Arne’s talk In Hall A, we plan to bring the closed 3H target cell on site for a full-year series of experiments on 3H. The plan is to return the 3H after one year to Sandia. This restricted duration puts pressure on the series of 3H experiments scheduled (they require 74 PAC days – exactly 23 weeks), especially with a long CR  Had to delay as we could only do a limited run this Spring Hall compatibility. E.g., the precision longitudinal-transverse separated cross section science program in Hall C often requires periods of changed linac energy settings, sometimes but not always compatible with the programs in other Halls  not a direct issue for 2017 given the schedule change, but relevant for 2018 + Cryogenics, polarization constraints, labor availability, facilities improvements, etc. 13

14 2015 NSAC Long Range Plan RECOMMENDATION I The progress achieved under the guidance of the 2007 Long Range Plan has reinforced U.S. world leadership in nuclear science. The highest priority in this 2015 Plan is to capitalize on the investments made.  Operate 12 GeV CEBAF RECOMMENDATION II We recommend the timely development and deployment of a U.S.-led ton-scale neutrinoless double beta decay experiment. RECOMMENDATION III We recommend a high-energy high-luminosity polarized EIC as the highest priority for new facility construction following the completion of FRIB.  Jefferson Lab EIC (JLEIC) development RECOMMENDATION IV We recommend increasing investment in small-scale and mid- scale projects and initiatives that enable forefront research at universities and laboratories.  MOLLER, SoLID

16 Integration IR: JLEIC total acceptance detectorPossible to get ~100% acceptance for the whole event Scattered electron Particles Associated with Initial Ion Particles associated with struck parton Relatively large crossing angle (50 mr) combined with large aperture final focus magnets, and forward dipoles are keys to this design.

17 Bunched Ion Beam Cooling – preliminary resultsA collaboration of JLAB and Institute of Modern Physics (IMP), China The 1st experiment was carried out on May 17-22, 2016, at Lanzhou, China A 7MeV/u 12C6+ ion beam stored in the IMP CSRm ring, either coasting or captured by 450kHz RF system (two long bunches) Cooling of both coasting and bunched ion by a pulsed electron beam are observed: first successful step of experimental demonstration of bunched beam cooling Data analysis both at IMP and JLAB is in progress Initial 1D modeling with RF capture and bunching shows the ion cooling and synchrotron sideband effects, agree with experimental observations Experiment data observation on BPMs cooled ion bunches uncooled ion bunches Electron bunches 1.5ms

18 JLEIC energy reach and luminosityJust implemented a baseline modification (essentially: add strong cooling back in and optimize collider parameters, but no change of concept) Baseline = 3T Note: Baseline choice is a mix of risk, total detection capabilities, energy/luminosity needs. Baseline gives access to start all science of EIC white paper.

20 Director’s PerspectiveEmphases Core Nuclear Physics Finish the upgrade project, safely, on time, and within budget. Full-time operations. Operations budgets continue to be a concern here. Reliability and Risk Mitigation Advance new NP projects beyond the upgrade Develop Jefferson Lab EIC design: Technical Designs, Collaboration, (Land now secured) Technology Collaborations Large projects, like FRIB and LCLS-II, within context of a Nuclear Physics program – management is key Management/Personnel Operations Functions: Facilities, Procurement, Financial Management, Budget Office, Human Resources, Information Technology, Legal, ES&H are vital to the functioning of the lab What the lab can achieve depends on your efforts, Jefferson Lab successes will be your successes.
