Electrostatic Quadrupole (ESQ) accelerators are capable of reliably accelerating high current, dc megavolt beams due to the low gradient structure and the electron suppression characteristics. Recently, LBL has been developing ESQ accelerators for injecting dc neutral particle beams into tokamak fusion reactors, or as pulsed-beam injectors of heavy ion induction linac drivers for inertial fusion reactors. A conceptual design of a 2.5 MeV proton ESQ accelerator for Boron Neutron Capture Therapy (BNCT) application is presented. For reasonable dose time (e.g. 1 hr.) the required current is around 100 mA. One major challenge in the design is the development of a compact dc power supply system. Some preliminary power supply concepts will be discussed.
