Research Highlights
  • Beam Dynamics and Lattice Design
    Study of beam transport in recirculating superconducting linacs, beam optics and lattice design for transport lines at CEBAF, development of an on-line beam optics analysis via differential orbit measurement, lattice design of a wide aperture recirculating linac muon accelerator for future neutrino factory.

  • Recirculating Linacs for Neutrino Factory
    Development of a conceptual lattice design for a 20-50 GeV muon accelerator based on recirculating SC linacs. Feasibility studies of acceleration and transport of a large phase-space of short-lived muons implemented in a proof-of-principle lattice for a recirculating linac accelerator based on 200 MHz. Appropriate lattice design choices combined with a sextupole correction to suppress chromatic effects are being explored to optimize beam transport in the proposed muon accelerator complex (straight linac and multi pass recirculating linac).

  • Novel Cooling and Acceleration Schemes, Crystal Channeling
    Concept of a crystal micronundulator based on channeling of relativistic particles through a strain modulated superlattice, E763 demonstration experiment at TRIUMF. High gradient (GeV/m) acceleration scheme based on laser pumping of a relativistic beam transversely excited by a modulated crystal channel. High gradient inverse Cherenkov acceleration-demonstration experiment at BNL.

  • Coherent Instabilities
    Analytic study of multi-bunch potential well distortion effects for a partially filled ring. Numerical simulation of the coupled bunch instability (longitudinal phase-space tracking). Nonperturbative analysis of the negative mas instability, Analytic studies of chromatic effects on the head-tail instability, Quasi-nonlinear Vlasov equation modeling of the saturation of collective instabilities and energy overshoot.
