ESQ accelerators are capable of producing high current, DC megavolt beams, thus they are ideal for BNCT application. n our preliminary design, a 3.6 m long ESQ column with a 6 cm bore diameter will accelerate a proton beam up to 2.5 MeV. The accelerator column is surrounded by an air-core transformer stack which provides DC power to the ESQ electrodes. The assembly is enclosed inside a 6.1 m long 2.4m diameter high pressure vessel. Computer simulation shows that the beam currents ranging from 25 mA to 125 mA.
