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.
