Abstract

An ogive shaped carbon-carbon composite (CCC) beam-stop has been designed to replace the original nickel ogive beam stop for the Low Energy Development Accelerator (LEDA) of the APT (Accelerator Production of Tritium) project. The nickel beam-stop has been used for initial testing of the 6.7 MeV, 100 mA cw proton beam from the APT RFQ (Radio Frequency Quadrupole). Because of activation concerns, another beam stop is needed for future tests on the first module of the Coupled-Cavity Drift-Tube Linac (CCDTL), which will increase proton beam energy to 10.4 MeV. The CCC ogive has been integrated into the nickel structure as a direct replacement. The design and fabrication of the CCC ogive beam-stop is presented with a review of the original nickel ogive design
