Stony Brook June 24-27, 2014
The following is just one person’s look into a (rather hazy) crystal ball, and any/all of what follows could be changed depending on any number of circumstances, e.g.
new science discoveries
new administration priorities,
Hadrons from QGP
Forces & Symmetries
Theory and Computation
There would appear to be a good 10 year program of compelling science to be done
Longer term, ATLAS niche is as a unique, complementary Stable Beam Facility for research on Nuclear Structure & Nuclear Astrophysics
FRIB will increase the number of isotopes with known properties from ~2,000 observed over the last century to ~5,000 and will provide world-leading capabilities for research on:
FRIB Site March 2014
FRIB Linear Accelerator
The coils of this high temperature superconducting (HTS) quadrupole exceeded the required currents at elevated temperatures, indicating additional operating current margin and more stability.
Ground breaking ceremony with participation by DOE officials and Senate and House representatives was held on March 17, 2014.
Polarized Jet Target
For the hot QCD science and polarized proton science missions, no other facility worldwide, existing or planned, can rival RHIC in range and versatility.
R&D on one of several approaches by U.S.
scientists is ongoing at Lead, South Dakota
With techniques that use nuclear isotopes inside cryostats, often made of ultra-clean materials, scientists are “tooling up” to study whether neutrinos are their own anti-particle.
NSAC has been charged to identify the criteria for a next generation double beta decay experiment.

Status of Ongoing and Planned Experiments
Maintaining adequate support for a robust nuclear theory effort is essential to the productivity and vitality of nuclear science
New GPU-based LQCD processor at TJNAF
How many different nuclei exist?
NP researchers theorize the number to be ~7,000
The mission of the DOE Isotope Program is threefold
Produce and/or distribute radioactive and stable isotopes that are in short supply, associated byproducts, surplus materials and related isotope services.
Maintain the infrastructure required to produce and supply isotope products and related services.
Conduct R&D on new and improved isotope production and processing techniques which can make available new isotopes for research and applications.
Produce isotopes that are in short supply only –
the Isotope Program does not compete with industry
R&D Creates New Production Method for Actinium-225

New LRP in 2007
First Mention of a Relativistic Heavy Ion Machine; Not Yet a Recommendation
The major facility recommended by this plan turned out to be CEBAF
Time from First Strong Recommendation to Operating Facility
RHIC: 1983 to 2000 17 years
CEBAF 12 GeV Upgrade 2002 to 2017 15 years
ISOL Facility/RIA/FRIB 1996 to 2021 25 years
CEBAF 1979 to 1996 17 years
There seems to be a constant of nature with respect to the timescale for realization of big initiatives
EIC at the moment has no status with respect to nuclear science community
priorities. The next LRP will be 2021
In addition to nuclear science priorities, there are other Office of Science priorities that will be in play
All kinds of things, always (ITER, LBNE,
New Light Sources, New Leadership Computers, new Centers, new Hubs, ...
EIC will either be in the swim
A very strong science case with broad appeal need to be clearly articulated to and bought into by the nuclear science community
(disclaimer, this is an observation, not an endorsement by the AD)
Free color charges (e.g. quarks) do not exist, but color dipoles do! Virtual photons are an excellent source of color dipoles.
HERA was the 1st
with limited intensity
and no polarization.
EIC will be a 2nd
High density phase of
cold gluon matter
Gluon structure of the proton:
How is the proton’s mass generated and what carries its spin?
A particular challenge for this aspect will be making the scientific challenges “fresh” and strongly motivated for a
~69% of the FY 2015 NP budget supports operations or construction of facilities
The percentage devoted to major projects is almost 19% in FY 2015
FY 2015 President’s Request
Total = $593.6M
Nuclear Science will continue to be an important part of the
U.S. science investment strategy to create new knowledge and technology innovation supporting U.S. security and competitiveness
