Our goal: to study all states of strongly interacting matter,

partonic, hadronic and nuclear,

& discover new ones

Quark-gluon plasmaRHIC/PHENIX & CERN/ALICE 6 staff physicists

Nucleon structureCERN/COMPASS & JLab/CLAS & Theory 11

Nuclear structure from SPIRAL to SPIRAL2,

+ the whole palette of radioactive beams & Theory 12

Interfaces between fundamental physics and applicationsspallation, neutron-induced reactions, nuclear energy,fission, non-proliferation, nuclear astrophysics 11

(+ 9 post-docs, 12 students, 2 scientific advisors, 2 direction, 2 administration, 2 technicians)

First generation of dedicated DVCS experiments in progress.

A clear perspective: GPD@JLab/12 GeV.

New theoretical concepts, innovative technics

Very rich harvest at COMPASS

→ ∆G, polarized parton distributions (L&T), spectroscopy…

Proposition to SPSC spring 2010, including GPD program.

Theory: - first lattice QCD results (ETMC),

- heavy baryon phenomenology

- baryon resonances.

CLAS12 Central DetectorCLAS12 Central Detector

Specifications driven by measurements of deep exclusive reactions

Detection of large angle/low energy recoil protons, e.g. in

PR12-06-119 approved DVCS on proton ALU, AUL & σ

Detection of large angle/low energy recoil neutrons, e.g. in

LOI12-09-001 DVCS on neutron strongly encouraged

First suggestion of a European enterprise (together with Korea, Russia and JLab)

by Volker

Central tracker: - fast cylindrical Micromegas becoming a real option - optimal resolutions with mixed Si/MM tracker - important for p-DVCS to reduce material thicknesses

Space available between CTOF and solenoid - unique opportunity to measure n-DVCS

CTOF- is the design frozen?

Common headache for all: large solenoidal field

Objectives for this meeting (1)Objectives for this meeting (1)

- Update on all subsystems

- Central tracker: (define the way to) optimize the mixed Si/MM configuration MM: any further proof of feasability required? Electronics

- Forward vertex tracker: any issues ?

- Neutron detector Brainstorming on conceptual design Define further R&D and/or simulations - CTOF Optimal configuration? Is a mixed system CTOF/neutron counter an option? If not, will Europe be involved?

Objectives for this meeting (2)Objectives for this meeting (2)

- Integration (exchange on design, organization, coordination,...)

- MoU’s and other formal aspects

- Agenda for all actions discussed during the course of the meeting
