Zhiyu Sun Pion production at IMP; HIC@NSCL

Zhigang Xiao Symmetry Energy, Fission at IMP, SpiRIT collaboration, NSCL experiments

FengShou Zhang Transport model, HiRA upgrade, SpiRIT collaboration

YingXun Zhang collaborative projects on EOS of Asymmetric matter; personnel exchange

FAIRGSI

Symmetry Energy Project

NSCL,RIKEN, FRIB, RAON LCSR

In addition to Symmetry Energy study, a new HIC initiative for IMP and NSCL/FRIB to exploreExploring Neutrinosphere with multifragmenation

Multiplet Observables to study Symmetry Energy

Top Wish list for SE study both in China and USTPC for pions

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

Future plan:CEE phase II conceptual design ~$20 M

Magnet DipoleBuilt 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

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 MICROMEGASCathode allows passage of charged particle ancillary detectors downstream.

Day 1 exp. :SRIT 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

Wish list for FRIB Equipment

:Trigger scintillators use MPPC readout

“If I seem unduly clear to you, you must have misunderstood what I said” Alan Greenspan

DOE Perspective



Establish a task force to explore the best way to develop collaborative endeavors in experiment and in theory that fit the participants’ needs and the agencies expectations.

Discussions:

Task force1. 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 Physicistsb. Needs of the US Physicists

2. Best practice for successful collaborations3. Find consensus on projects of mutual benefits and

interest that fit into the agencies vision and mission.4. Get funding and support.
