The design and development of large-scale particle accelerators, such as the system being pursued at MSU -- the Facility for Rare Isotope Beams (FRIB) -- and the subsequent stability of particle motion within these accelerators have been the focus of my research over the years. Before arriving at MSU in 2010, my career has involved designing, building, commissioning, operating, and experimentally studying large particle accelerators for fundamental physics research, including work on the Main Ring, Tevatron, Main Injector, and other injectors at Fermilab; the Superconducting Super Collider in Texas (construction halted); Brookhaven National Labs AGS and RHIC (as a polarized proton collider); and the LHC at CERN. I also have participated in early design studies of the International Linear Collider and Muon Collider concepts.
Particle beam optics and accelerator design, nonlinear particle beam dynamics, and novel uses of beam instrumentation and diagnostics for measuring and monitoring beam and accelerator properties have been the emphasis of my work. The FRIB project at MSU brings several new demands to the accelerator field in these regards. The wide range of particle velocities coupled with the intense beam power on target -- to approach half a Megawatt -- pose new challenges to beam intensities, efficiencies, and the need for flexible systems of particle containment, focusing, and optimization.
The MSU Re-accelerator (ReA) not only provides a unique system for methodically studying nuclear systems found in astrophysical environments, but also provides opportunities for research into novel beam diagnostic systems and a test bed for the development of superconducting cavity systems and beam systems that can be used in FRIB and other future particle accelerators. My group takes advantage of the wide variety of beam species and particle beam conditions at ReA to pursue unique and varied opportunities in beam research.
I am also involved in the development of storage rings and beam lines that can be used in measurements of anomalous magnetic moments (in particular the muon system) and searches for non-zero electric dipole moments of particles. As a member of the Muon g-2 experiment at Fermilab and the Storage Ring EDM Collaboration, studies of the particle beam storage and transport systems used in these experiments involve fundamental design, CPU-intensive computational studies, as well as experimental investigations for verification. Such investigations in turn explore the full potential of accelerator facilities operating at the intensity frontiers of nuclear and high energy physics.
The typical beam position monitor does not resolve individual particles. However, if the beam is intentionally offset from the ideal trajectory it will oscillate due to the focusing fields of the accelerator. An analysis of the resulting signal can give information about the nonlinear properties of the accelerator and of the energy spread of the beam.
