Abstract
Traveling wave SRF accelerating structures offer several advantages over the traditional standing wave structures: substantially lower and lower , ratios of peak magnetic field and peak electric field to the accelerating gradient, respectively, together with substantially higher . In this paper we discuss how a linear collider Higgs Factory HELEN can be built using TW-based SRF linacs. We cover a plan to address technological challenges and describe ways to upgrade the collider luminosity and energy.
