Beam intensity limits in the Main Injector through transition with a normal phase jump scheme

Abstract

The Fermilab Main Injector, which is under construction, will be a high intensity proton synchrotron and will be capable of accelerating (decelerating) protons and antiprotons from 8.9 GeV/c to 150 GeV/c (150 GeV/c to 8.9 GeV/c). Presently, the plan is to accelerate or decelerate the beam through the transition energy of 20.49 GeV, using basic normal phase jump scheme. Efficient deceleration ofp through the Main Injector is crucial for the success of the Recycler Ring Project. We have performed extensive longitudinal beam dynamics simulations for both modes of operation to determine the beam intensity limits and other properties. We present the latest results of calculation and their implications.
