LANSAR® - Product Summary
LANSAR® systems from AccSys Technology, Inc. are powerful neutron sources based
on compact ion linear accelerators (linacs). The ability to choose from among
several possible combinations of beams and targets provides a wide range of
output neutron yields and energy spectra. Yields at the target range from
108 neutrons/second from the compact Model DL-1 system to more than
to 1013 neutrons/second from the powerful Model PL-11. LANSAR®
systems are capable of operating in harsh environments and are ideally suited
for many neutron applications in non-destructive testing.
LANSAR® Units for Neutron Radiography
LANSAR® neutron generators can replace conventional neutron sources for
applications ranging from corrosion detection in aircraft structures to void
detection in munitions. AccSys systems have been used for both fast neutron and
resonant neutron radioscopy. Rather than transporting components to a reactor
for inspection in applications such as examination of epoxy bonds covered by
metals, high resolution radioscopy can now be performed at the factory or
assembly site.
LANSAR® Systems for Neutron Analysis
LANSAR® neutron generators have demonstrated their utility as fast or thermal
neutron sources in applications as diverse as radioactive waste assay,
contraband detection, mineral assay and neutron gauging.
LANSAR® Generators for Medical Use of Neutrons
LANSAR® neutron generators can provide fast, epithermal, or thermal neutron
beams for medical applications such as neutron capture therapy.

LANSAR® System Features and Advantages
LANSAR® units contain no radioactive material. Minimum target and beam
degradation over years of operation results in a long lifetime at full neutron
output intensity. The neutron production target can be located far away from the
accelerator which reduces moderator and shielding requirements. Full AC power is
required only during operation resulting in low power consumption. Service and
maintenance can be performed at the installation site resulting in lower
operating and repair costs than other neutron generators. LANSAR® units are easy
to operate and maintain, featuring modular construction and computer control
with self-diagnostics.
LANSAR® systems are rugged and transportable with external power supplies and
no moving parts in the accelerator. The light weight and compact size of these
rugged and efficient accelerators make them easily transportable. The modular
design allows flexibility for installation in any facility. For all of their
advanced features, AccSys ion linacs provide the benefits of simplified
operation, easy maintenance and low operating cost.
LANSAR® System Components
- Pulsed ion injector with a duoplasmatron ion source provides a high current
proton or deuteron beam
- Linear accelerator (typically a single RFQ but a second stage DTL is used
for beam energies greater than 4 MeV)
- Pulsed rf power system featuring compact and reliable multiple planar-triode
technology
- Vacuum system consisting of commercial cryopumps or turbomolecular pumps
with computer-automated controls
- PC-based control system with built-in diagnostics
- Self-contained cooling system
- Standard target consisting of a beryllium sheet brazed onto an air- or
water-cooled copper backing
