Description

The Brazilian Center for Research in Energy and Materials (CNPEM) has initiated a proton linear accelerator development program aimed at broadening its expertise in accelerator technologies to enable future applications. As a first step in this initiative, a 1 MeV proton Radio Frequency Quadrupole (RFQ) operating at 476 MHz was designed, manufactured, and assembled in Brazil, and is currently under commissioning. This work discusses aspects of the beam dynamics, vane modulation design, and beam measurements of the prototype. Emphasis is given to comparisons between simulations and experimental measurements, including RFQ transmission, spectrometer-based characterization of the accelerated beam, and pre-RFQ emittance measurements. The comparisons provide insights to the team and increase overall confidence in engineering solutions adopted during the development, including the vacuum sealing strategy based on 3D O-rings. Finally, future developments planned for this initiative are outlined.
