C3Demo, a cool path towards the next generation high efficient compact LINAC

SLAC has been investigating the feasibility of hosting the demonstration of Cool Copper Collider technology as an alternative approach for high energy e+e- collider [1]. This technology is based on the break through that SLAC researchers have made in pushing normal conducting RF acceleration structure towards extreme high gradient [2,3]. The ongoing design study aims for putting together a coherent plan and roadmap for addressing the required R&Ds to bring this technology towards more compact and cost-effective high energy linac.  This talk will present the status along with brief introduction of accelerator R&Ds at SLAC.
