Description

Beam cooling is a crucial step for the luminosity delivery system in a linear collider or an accelerator based light source to achieve ultra low beam emittance required for high luminosity and high brightness, respectively. Damping rings equipped with wiggler magnets and accelerating cavities were previously proposed for systematic reduction of horizontal phase space area through radiation reaction whilst compensating for longitudinal momentum loss. In this paper, the concept of plasma undulator and its effective model analogous to a magnetic wiggler as well as its relation to damping properties were recapitulated. EPOCH simulations for the laser propagation optimisation are presented; formation of an order of magnitude larger undulator field compared to conventional wigglers is demonstrated. In conclusion, an existing conventional damping ring design was reviewed to explore the indications of an upgrade to plasma technology.
