STRUCTURAL ANALYSIS OF SUPERCONDUCTING ACCELERATOR CAVITIES

Conference ·
OSTI ID:768897
The static and dynamic structural behavior of superconducting cavities for various projects was determined by finite element structural analysis. The {beta} = 0.61 cavity shape for the Neutron Science Project was studied in detail and found to meet all design requirements if fabricated from five millimeter thick material with a single annular stiffener. This 600 MHz cavity will have a Lorentz coefficient of {minus}1.8 Hz/(Mv/meter){sup 2} and a lowest structural resonance of more than 100 Hz. Cavities at {beta} = 0.48, 0.61, and 0.77 were analyzed for a Neutron Science Project concept which would incorporate 7-cell cavities. The medium and high beta cavities were found to meet all criteria but it was not possible to generate a {beta} = 0.48 cavity with a Lorentz coefficient of less than {minus}3 Hz/(Mv/meter){sup 2}.
