                  FRONTIERS OF ION BEAM
       RESEARCH FOR "NANOSCIENCE AND NANOTECHNOLOGY"

                       S. K. Guharay

Intense, high-brightness ion beams find applications in a wide range
of areas covering both basic and applied science. Examples in basic
science include beams in a high-energy accelerator, such as collider
at the Fermi National Accelerator Laboratory, Spallation Neutron
Source at Oak Ridge National Laboratory. Another important example is
its role in providing supplementary heating to achieve ignition of
high-temperature plasmas in fusion reactors. The modern technological
applications of ion beams include a highly diverse arena, for example,
surface science, development of novel materials, ion beam microscopy,
ion beam lithography, and low and medium-energy ion beam scattering.
The current state-of-the art of ion beam technology falls far short of
the needs in many applications, especially as its merits to approach
the sub-micrometer domain are examined. This talk will develop the
fundamentals of ion beam research, address needs in many critical
applications and shed light on probing into the new realm of
=93nanoscience and nanotechnology=94, for example, micro and
nano-machining of features to follow the International Technology
Roadmap for Semiconductors, high-resolution probes for diagnostics of
semiconductor devices, and above all, studies of critical problems in
biology and medicine.
