2. Beam Physics and Astrophysics Group • Production of high-brightness electron beams at FNPL • High Resolution electron beam diagnostics • Interferometry (transition radiation) • Electro-optic sampling (electromagnetic fields) • Theory and Simulation of space charge • Chaos in time-dependent systems • Chaotic mixing in N-body systems (beams, galaxies) • Validity of the continuum (Vlasov) limit • Beam halo formation • New multiresolution algorithms (e.g., application of wavelets). • Eight FY03 pubs…

3. [C.L. Bohn, I.V. Sideris, Phys. Rev. ST Accel. Beams6, 034203 (2003)] Snapshots of four different clumps of chaotic orbits in a TE beam bunch with triaxial symmetry. Each clump grows exponentially to fill a volume commensurate to the total particle energy. Moral: Chaos can appear in simple static beams; thus one can expect (and one generally sees) chaos and fast collective dynamics in nonequilibrium beams! Example: Chaotic Orbits in Thermal-Equilibrium Beams

4.
