Minimization model tools [Fermilab accelerators]

Description

This item was taken from the IEEE Conference ' Minimization model tools [Fermilab accelerators] ' Accurate beam steering is crucial for transfers between different accelerators in the Fermilab accelerator complex. During commissioning of the new 8-GeV beam transfer line from Fermilab Booster to Main Injector, we used a least square fit algorithm to achieve the desired beam line orbit. The program is based on the COCU orbit correction package used at CERN. The purpose and the need of this program is to keep the desired injection trajectories to the Fermilab Main Injector (FMI) constant and minimize the time required to tune the beam line. In addition, we performed a number of measurements to compare the optics of the line to the design values. In this paper, we present the experience with the beam line steering in the 8-GeV line during commissioning and the results of detailed beam line studies.
