Amy Sy

   *Skew PIC: Modified genetic algorithm on ifarm to generate Gaussian-distributed individuals instead of uniformly-distributed individuals for optimization of large variable sets. Considered Chebyshev expansion of magnetic fields and optimizing nonlinear optics in Skew PIC channel in terms of Chebyshev polynomial coefficients instead of standard Taylor series approach. "Chebyshev-like" approach forces simultaneous optimization of sextupole and octupole components, which reduces the beam size by ~25% for the same initial distribution.
   *Merger: Implementing a transition section between straight and toroid sections to best avoid emittance growth. Still working on verifying magnetized distribution properties from distribution created using a flat beam transform and propagating through a solenoid.
