Energy Recovery Linacs are a new kind of linear accelerators. To use such an accelerator
to construct an x-ray source poses many challenges.
This course will introduce into accelerator physics, emphasizing the aspects
that are most relevant for the design and construction
of an x-ray source based on this new kind of high-energy electron accelerator. There
will be guest lectures by several important players in Cornell's effort to
build an Energy Recovery Linac.
