Query: Structural Analysis of Superconducting Accelerator Cavities   The static and dynamic structural behavior of superconducting cavities for
various projects was determined by finite element structural analysis. The b =
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 -1.8 Hz/(Mv/meter)2 and a lowest structural resonance of
more than 100 Hz. Cavities at b = 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 b = 0.48 cavity with a Lorentz coefficient of less than
-3 Hz/(Mv/meter) 2.
