Fully Coupled Analysis of Orbit Response Matrices at the FNAL Tevatron

Optics measurements have played an important role in improving the performance of the Fermi National Accelerator Laboratory (FNAL) Tevatron collider. Initial optics measurements were performed using a small number of differential orbits, which allowed us to carry out the first round of optics corrections. However, because of insufficient accuracy, it was decided to apply the response matrix analysis method for further optics improvements. The response matrix program developed at Argonne National Laboratory (ANL) has been expanded to include coupling – the essential feature required to describe the Tevatron optics. The results of the optics calibration are presented and compared to local beta function measurements.
