Title: Tinkering at the main-ring lattice

Abstract

To improve production of usable antiprotons using the proton beam from the main ring and the lossless injection of cooled antiprotons into the main ring, modifications of the main ring lattice are recommended.

  • Studies of the NLC Main Damping Ring lattice since April 2001 have indicated that there are a number of collective effects that potentially limit operational performance. One possible way to reduce the impact of these effects is to raise the momentum compaction of the lattice, which requires a significant re-design. In this note, we present a lattice that has a momentum compaction four times larger than the previous design. We discuss the linear and nonlinear dynamical properties of the lattice, and present some initial estimates of the sensitivity of the new design to various magnet misalignments.
  • I give a brief introduction to the purpose and goals of the EMMA experiment and describe how they will impact the design of the main EMMA ring. I then describe the mathematical model that is used to describe the EMMA lattice. Finally, I show how the different lattice configurations were obtained and list their parameters.
  • A main-ring lattice that avoids crossing transition energy during acceleration when injected by a low-energy booster is discussed. Included in the report are a list of parameters, plots of lattice and orbit functions, and output from program SYNCH.
