Currently the facility utilizes two 750 keV Cockcroft-Walton (CW) based injectors for transporting H⁺ and H⁻ beams into the 800 MeV accelerator. A Radio Frequency Quadrupole (RFQ) design is being proposed to replace the aged CW injectors. An important component of the RFQ Test Stand is the Faraday cup that is assem-bled at the end of the Low Energy Beam Transport (Phase 1 LEBT) and Medium Energy Beam Transport (Phase 3 MEBT). The Faraday cup functions simultaneously as both a beam diagnostic and as a beam stop for each of the three project phases. This paper describes various aspects of the design and analysis of the Faraday cup. The first analysis examined the press fit assembly of the graphite cone and the copper cup components. A finite element analysis (FEA) evaluated the thermal expansion proper-ties of the copper component, and the resulting material stress from the assembly. Second, the beam deposition and heat transfer capability were analyzed for LEBT and MEBT beam power levels. Details of the calculations and analysis will be presented.
