Abstract
Significant progress has been made in the development of new modest-size compact stellarator devices that could test optimization principles for the design of a more attractive reactor. These are 3 and 4 field period low-aspect-ratio quasi-omnigenous (QO) stellarators  based on an optimization method that targets improved confinement, stability, ease of coil design, low-aspect-ratio, and low bootstrap current .
