General Company Information
AccSys Technology, Inc. (AccSys) is a privately-held California corporation with
its plant and corporate headquarters in Pleasanton, California. The company has been
an affiliate of Hitachi, Ltd., the majority shareholder since 2002. AccSys has
established itself as a leader in the commercialization of ion linac technology and
is dedicated to the design and production of high-quality, reliable systems to meet
the needs of commercial markets for compact ion linacs. AccSys has complete in-house
design capability for rf ion linacs and has cultivated a working association
with a number of research laboratories to continue development of state-of-the-art
technology. AccSys has designed, built and delivered dozens of ion linacs worldwide
since demonstrating its first prototype in 1987.
Design and Manufacturing
AccSys has an experienced team of management, technical and manufacturing
personnel. The senior scientific and engineering staff of highly-qualified physicists
and engineers form the technical foundation of the company and have extensive
experience in the design, production, testing and servicing of rf ion linacs and
rf amplifier systems.
Our in-house design capability includes proprietary versions of
all of the standard rf accelerator design codes and full CAD capability for
design of mechanical parts and electronic circuits. Specialized tooling has been
developed for the precision measurements required to insure production of the
highest quality and most efficient compact ion linac systems.
AccSys presently occupies 17,000 square feet of space, of which
12,000 square feet are devoted to manufacturing. The facility includes a CMM
inspection system, with a 40" x 24" x 18" capability at 6 micron accuracy; a
fully equipped accelerator and amplifier tuning and measurement laboratory; an
electronics fabrication, assembly and test area; rf and accelerator system
assembly, testing and commissioning areas; and an in-house machine shop that
include CNC mills, large lathes, a welding and brazing shop, and all support equipments.
Large mechanical parts are precision machined to our specifications by qualified
outside shops using CAD drawings generated by the engineering design group. A
dependable network of qualified shops and specialized vendors ensures on-time parts
delivery. In-house prototype shop, rf tuning lab, and specialized tooling and fixturing
expedite system assembly and commissioning under stringent quality standards. Most
electronics fabrication, assembly and testing is done in our facility. All
accelerator system design, assembly, testing and factory acceptance are done
in-house as well.
Milestones in AccSys History
Major accomplishments during the first 19 years:
- First mobile PET facility introduced
- Three technology transfer agreements with federal laboratories for state-of-the-art
accelerator capability.
- Eight patents awarded on rf linac technology and applications.
- Four Cooperative Research and Development Agreements (CRADAs) with DOE research laboratories.
- Pioneered the development of neutron generators based on the use of an RFQ linac and
established the LANSAR® product line for
applications in non-destructive testing.
- Introduced a standard-setting family of linac-based PULSAR®
systems to replace older, conventional technology (i.e. cyclotrons) for the cost-effective
production of positron tracers for diagnostic medical imaging.
- Delivered four systems for use in proton beam cancer therapy to facilities in
the U.S., Japan and Italy.
