Approaches to High Intensities at FAIR
A new accelerator complex is planned to gen-
P.J. Spiller, W. Barth, H. Eickhoff, P.S. Spaedtke (GSI)
erate highest intensities of heavy ion and proton
beams for the Facility for Antiproton and
Ion Research (FAIR) at GSI. The two new synchrotrons, SIS100 and SIS300 which deliver the primary beams to the
FAIR target stations, will make use of the existing GSI accelerators UNILAC and SIS18 as injectors. In order to reach
the desired intensities close to 1012 uranium ions and 2.5 x 1013 protons per pulse, a substantial upgrade program
of the existing facility is being prepared. The well defined technical subprojects of these upgrade programs and the
concepts for approaching the intensity goals of SIS100/300 will be described.
Commissioning Highlights of the Spallation Neutron Source
The Spallation Neutron Source (SNS) is a
N. Holtkamp (ORNL)
second generation pulsed neutron source at
Oak Ridge National Laboratory. The SNS is
funded by the U.S. Department of Energy’s Office of Basic Energy Sciences and is dedicated to the study of the structure
and dynamics of materials by neutron scattering. A collaboration composed of six national laboratories (ANL,
BNL, TJNAF, LANL, LBNL, ORNL) is responsible for the design and construction of the various subsystems. With
the official start in October 1998, the operation of the full facility has begun in late spring 2006 delivering a 1.0 GeV
proton beam with a pulse length of approximately 700 nanoseconds on a liquid mercury target. Within the next two
years a beam power of more than one MW should be achieved. The multi-lab collaboration provided a large variety of
expertise in order to enhance the beam power delivered by the accelerator by almost an order of magnitude compared
to existing neutron facilities. The SNS linac consists of a room temperature and superconducting (sc) structures and
is the first pulsed high power sc linac in the world. The compressor ring and the target are the final subsystems that
were commissioned during early 06.
