  The Integrable Optics Test Accelerator (IOTA) is proposed for operation at
Fermilab. The goal of IOTA is to create practical nonlinear accelerator
focusing systems with a large frequency spread and stable particle motion. The
IOTA is a 40 m circumference, 150 MeV (e-), 2.5 MeV (p+) diagnostic test ring.
A heavy low frequency steel floor girder is proposed as the primary tier for
IOTA device component support. Two design lengths; (8) 3.96 m and (2) 3.1 m
long girders with identical cross section completely encompass the ring. This
study focuses on the 3.96 m length girder and the development of a working
prototype. Hydrostatic Level Sensor (HLS), temperature, metrology and fast
motion measurements characterize the anticipated mechanical stability of the
IOTA ring.
