• SoLID: large acceptance, capable of handling high luminosity (up to~1039 with baffle, up to ~1037 without baffle)

Ideal for precision Inclusive-DIS (PVDIS) and SIDIS experiments Excellent for selected exclusive reactions (ex. J/Psi)

• Five high impact experiments approved ( 4 with “A” rating, 1 A- rating):

PVDIS, E12-10-007 SIDIS: E12-10-006 (He3-T), E12-11-007 (He3-L), E12-11-108 (p-T) J/Psi: E12-12-006

SoLID Overview/PhysicsJ. P. Chen, Hall A Meeting, 12/18/2012

Nucleon Structure with SoLID Semi-inclusive Deep Inelastic Scattering program: Large Acceptance + High Luminosity+ Polarized targets 4-D mapping of asymmetries Tensor charge, TMDs …Lattice QCD, QCD Dynamics, Models.

International collaboration (8 countries,50+ institutes and 190+ collaborators)• Rapid Growth in US China Collaboration‐(2 grants from NSFC + MOU)• Chinese Hadron collaboration(USTC, CIAE, PKU, Tsinghua U, +)

- large GEM trackers- MRPC-TOF

Five experiments approved for SoLID with two having Chinese collaborators as co-spokesperson (Li from CIAE and Yan from USTC)

Solenoidal Large Intensity Device (SoLID)

Parity Violation with SoLID

Parity-violating Deep Inelastic Scattering:

• High Luminosity on LD2 and LH2 • Better than 1% errors for small bins

over large range kinematics• Test of Standard Model • Quark structure:

b(x): weak couplinga(x): quark structure information

• Magnet: Continue work with CLEO magnet /support BaBar option: Decision to go with CLEO

• Simulations: Baffle, GEM/tracking/DAQ inputs, … Background, neutrons

• Detectors: “finalize” conceptual designLight Cherenkov, support, PMT (Temple+), backup:HBD (Stonybrook)Heavy Cherenkov, support (Duke+)Calorimeters (UVa/Los Alamos+)GEMs (UVa+): Large size, Readout, R&D with SuperBBGEMs- China: foil production, medium size, readoutMRPC (Tsinghua+)

• DAQ (JLab/UMass): concern GEM readout size solution (with de-convolution, 1 sample)

• Other sub-systems: Targets Beam Polarimetry, …

SoLID Collaborators from China

• Charge for Director’s Review (Rolf’s talk last meeting)• 1st draft of technical write-up on SoLID (~80%)

• http://solid.physics.umass.edu/~seamus/solid_techprop.pdf• baseline equipment list• rough cost (exclude GEMs (China), DAQ/electronics(JLab)): ~$25-30M

• JLab input to NSAC sub-committee• SoLID funding profile 2016-2018, request US funding ~$35M

• Schedule Director’s review (Late Spring/Summer?) Discuss with DOE Submit MIE (late 2013?) CD process (2013-2015?)

• Preparation “Freeze” the conceptual design on susbsystems (Dec. 2012) Move forward with the magnet (decision on Babar option) Design support structure, integration, configuration change-over More detailed cost/manpower estimation Sub-system responsibilities / R&D needs Finalize the technical document (Jan/Feb?) Resources: attract more collaborators, other sources of funding
