Particle accelerators are major tools for discovery in nuclear
physics, high energy physics and basic energy science. A
new national-user facility for nuclear science, FRIB is based
on a state-of-the-art 400 kW superconducting linear
accelerator. FRIB employs large number of accelerator
physicists and engineers and attracted significant
DOE funding for education of graduate students under
ASET program. Currently, FRIB is approaching to the
commencement of user operation. The main focus of
the Accelerator Physics Department is the detailed
understanding of beam physics issues in this new facility to
achieve the design beam power and deliver wide selection
of isotopes to the experiments. A significant innovative
engineering effort will be necessary to achieve routine
operation with 400 kW beam power. At the same time,
research and development (R&D) for future FRIB upgrade
scenarios is being pursued to enable new high-priority
and high-impact research opportunities. This task requires
strong communication between accelerator physicists,
engineers and nuclear physicists to understand the highest
priority research. The list of possible short-term and midterm
accelerator R&D goals includes the development of
a cost-effective option for a high energy upgrade of the
FRIB driver linac which will be based on newly developed
medium-beta superconducting (SC) cavities (see the
photo) capable of doubling the energy of FRIB beams over
the available space of 80 meters.

Other R&D tasks include the development of multitarget
driver linac operation with the simultaneous
acceleration of light and heavy ions, and the development
and implementation of techniques to increase efficiency
for delivery of radioactive ion beam species to the
user experiments, the post-accelerator, and their postacceleration.
The long-term accelerator R&D will enable the
best science in the world at an expanded FRIB which may
include storage rings and a radioactive-ion-electron collider.
These accelerator R&D topics open vast opportunities
to involve PhD students and post-doctoral researchers.
In the past 10 years I have guided a group of scientists,
engineers, young researchers, students, and technicians
who have developed and implemented several innovative
accelerator systems such as high performance SC cavities
and cryomodules, a CW RFQ with trapezoidal vane tip
modulations, an EBIS for the fast and efficient breeding of
radioactive ions; designed and demonstrated several new
accelerating structures for ion linacs, developed and built
bunch length detectors for CW ion beams, and profile and
emittance measurement devices for rare-isotope beams.
The photo shows the newly developed room-temperature
continuous wave accelerating structure built for bunching
of FRIB beams after the stripper.

I eagerly look forward to applying this expertise to new
and challenging technical issues with students and postdocs
at FRIB.
