Why PERLE?

A half-century after the first description of energy-recovering linacs (ERLs) by M. Tigner [1], the promise of this architecture to provide linac-quality beam at storage-ring efficiency [2] remains elusive but persistent. We will describe the motivation for ERLs and how they operate, survey the contemporary ERL landscape, review progress to date, and detail challenges confronting upcoming generations of these machines. An overview of applications (servicing FELs, high-energy electron cooling systems, inverse Compton-driven gamma sources, internal-target experiments, accelerator science/technology test platforms) will be given, and the accelerator design status of PERLE - a Powerful Energy Recovery Linac for Experiments [3] outlined.
