We describe the present status of an ongoing project to develop a Tandem-ElectroStatic-Quadrupole (TESQ) accelerator facility for Accelerator-Based (AB)-BNCT at the Atomic Energy Commission of Argentina. The project final goal is a machine capable of delivering 30 mA of 2.4 MeV protons to be used in conjunction with a neutron production target based on the ⁷Li(pn)⁷Be reaction. The machine currently being constructed is a folded TESQ with a high-voltage terminal at 0.6 MV, due to building limitations, intended to work in air. Since the concept is modular the same structure will be used for the 1.2MV final accelerator. We report here on the progress achieved in a number of different areas like the mechanical, electromechanical and electronic structure closely linked to the hardware of the facility. Additionally, aspects related to the electrostatic field assessment, beam transport, accelerator tubes, ion sources, beam shaping assembly and patient treatment room, computational dosimetry and treatment planning, on-line dose determination system and alternative neutron producing reactions will only be briefly highlighted since they will be presented in detail in other contributions to this conference.
