3. Collaboration Projects (successful between small groups) Pawel DanielewiczTransport models, pion production, symmetry energy Chuck HorowitzExploring Neutrinosphere, a new HIC initiative for IMP and NSCL/FRIB Bao-An LiHIC theory collaborations Y.G. MaRHIC STAR collaborations; TAMU personnel exchange Betty TsangHIC Symmetry Energy (experiment & theory); Transport model; SpiRIT collaboration; personnel exchange Zhiyu SunPion production at IMP; HIC@NSCL Zhigang XiaoSymmetry Energy, Fission at IMP, SpiRIT collaboration, NSCL experiments FengShou ZhangTransport model, HiRA upgrade, SpiRIT collaboration YingXun Zhangcollaborative projects on EOS of Asymmetric matter; personnel exchange

4. FAIR  GSI Symmetry Energy Project NSCL,RIKEN, FRIB, RAON LCSR In addition to Symmetry Energy study, a new HIC initiative for IMP and NSCL/FRIB to explore Exploring Neutrinosphere with multifragmenation

5. Multiplet Observables to study Symmetry Energy Top Wish list for SE study both in China and US TPC for pions

7. CEE Phase I (Sun et al) CEE : CSR External-target Experiment ( 兰州外靶实验 ) At the forward angle, the probe of π - /π + is more sensitive to the symmetry energy. Target START TOF Wall Neutron Wall MWDC (Multi-Wire Drift Chamber) Magnetic Dipole

8. Future plan: CEE phase II conceptual design ~$20 M Magnet Dipole Built for FAIR by Lanzhou MRPC (used in STAR) ( Multigap Resistive Plate Chamber ) At the forward angle, the probe of π - /π + is more sensitive to the symmetry energy. TPC 时间投影室

9. For NSCL/FRIB: HRTAC-AT (~1 M for TPC, & 1M for electronics) Adopts much of the design of the AT-TPC Solenoidal magnetic field (using portable MRI magnet). MICROMEGAS gas amplification Standalone operation in S2 vault for EoS and other reactions studies Operation in S3 vault for Giant Resonance and charge exchange reactions Differences: Beam enters through MICROMEGAS Cathode allows passage of charged particle ancillary detectors downstream.

10. Day 1 exp. :S  RIT TPC inside SAMURAI Dipole Allows particle to travel to downstream detectors. Designed to be used with charged particle and neutron TOF walls, such as NEBULLA and NeuLAND. Rails allow TPC to be readily inserted and removed from SAMURAI magnet chamber : Trigger scintillators use MPPC readout

11. Wish list for FRIB Equipment : Trigger scintillators use MPPC readout $20 M Dipole Magnet @FRIB?

17. Discussions: Task force 1.Survey the needs from working scientists (not just the workshop participants which are biased and not representative of the community). a.Needs of the Chinese Physicists b.Needs of the US Physicists 2.Best practice for successful collaborations 3.Find consensus on projects of mutual benefits and interest that fit into the agencies vision and mission. 4.Get funding and support.
