Overview
LANSAR® neutron generators use AccSys' patented linac technology to provide compact systems designed for reliable long-term operation in non-destructive testing applications. These powerful but easy to use units provide neutron outputs from 108 to 1013 neutrons/second by bombarding robust beryllium (Be) targets with proton or deuteron beams.
The neutron output is pulsed and remains constant over may years of target lifetime. These systems can also be supplied with a variety of other targets, including deuterium. The neutron energy produced by a LANSAR® system can therefore be tailored to a specific requirement by selection of beam energy and target. The light weight, compact size, and rugged construction make LANSAR® systems easily transportable. As with all AccSys products, the modular design allows maximum flexibility for installation in an existing facility. These systems are proven to operate reliably under harsh conditions in the field. For all of its advanced features, LANSAR® is simple to operate and easy to maintain, with low operating costs.
The LANSAR® family of linear-accelerator-based neutron generator systems have been developed specifically for reliable long-term operation for non-destructive inspection applications in research and industrial environments. These are compact systems based on AccSys' patented compact ion linac technology and rugged beryllium neutron production targets. A broad range of configurations are available to provide outputs ranging from 108 to 1013 neutrons/second at the target for fixed or mobile applications. Key features of LANSAR® neutron generators include:
- No radioactive materials
- Target lifetime of many years at full neutron output
- Field serviceable with low maintenance and operating costs
- Rugged units that are transportable in most configurations
- Reduced shielding and moderator size
- Easy to operate and maintain
- Computerized control and monitoring
- Variable intensity and pulse structure
- Thermal, epithermal or fast neutron beams configurations
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 boron neutron capture therapy (BNCT).
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.
