A new study of the Main Ring physical aperture

Changes made to the Fermilab Main Ring lattice and the Main Ring's future importance for the HEP program require a new study of its physical aperture. This task has been carried out using a computer program that automatically and systematically measures the available aperture around the ring. This program and its performance are described along with a preliminary analysis of the results. Further systematic analysis of aperture data is underway in preparation for modifications to be made in the coming summer shutdown.<
