Abstract

The use of boron neutron capture therapy in clinical treatment will require the development of intense neutron sources suitable for operation in a hospital environment. Low-energy accelerator-based neutron sources have the potential for meeting the requirements for a clinical BNCT facility. This paper describes the design, installation, and initial operation of the first high current tandem accelerator for this application. The accelerator utilizes a highly power efficient switch-mode high voltage generator to deliver proton beams with energies of up to 4.1 MeV. The use of a multi-cusp high current negative ion source in combination with magnetically suppressed accelerating tubes allows the acceleration of proton beam currents up to 4 mA. The design principles and operation of the accelerator are described.
