Mechanical studies of the Fermilab low beta quadrupole collared coils

Finite element results of Low Beta Quadrupole magnets are compared to measurements from three mechanical models. Stress, as measured with internal strain gauges, and radial deflections, as measured with a precision measuring device, are compared to the finite element analysis. The results indicate that measured internal pressures are in agreement with calculations but measured deflections are approximately lower than predicted. The findings will help develop better analyzing and manufacturing techniques to be used on developing the High Gradient Quadrupole magnet.
