A proton Super-Conducting Linac has been proposed to drive an internal solid target placed at the core of the de-commissioned High-Flux Breader Reactor (HFBR) of Brookhaven National Laboratory. The purpose is to take advantage of the HFBR instrumentation and facility for the generation of a continuous, high-intensity neutron source. The Super-Conducting Linac driver accelerates protons to 1 GeV, operates in a Continuous-Wave mode (CW), and generates an average beam power of 10 MWatt. The average beam current is 10 mA, and the total length about 300 m. The Linac is made of three parts: a Front-End, that is a 15 mA ion source, followed by a 5-MeV RFQ, a room temperature 150-MeV Drift-Tube Linac (DTL), and the Super-Conducting Linac (SCL) proper. This is made of two sections: the medium-energy section that accelerates protons to 300 MeV, and the high-energy section that accelerates to 1 GeV. The selected operating frequency is 805 MHz. A spreadsheet program has been used for the design and cost estimate. The design has shown that the accelerator is feasible, can be build in a relatively short period of few years, and has an estimated total cost of about 300 M$.
