Updated baseline design for HALHF: the hybrid, asymmetric, linear Higgs factory

This paper presents an updated baseline design for HALHF, a hybrid, asymmetric Higgs factory that combines plasma-wakefield acceleration for electrons with radio-frequency acceleration for positrons to overcome efficiency challenges and reduce costs, detailing the optimization process used to address issues identified in the original proposal.

High Power RF Pulse Shaping Tests with NG-LLRF and Cool Copper Collider Prototype Structure

This paper demonstrates high-power RF pulse shaping experiments using a digital-only Next Generation LLRF (NG-LLRF) platform and a Cool Copper Collider prototype, achieving peak powers up to 5.4 MW and validating the system's capability to perform complex modulations like phase reversal and beam loading compensation without additional analog components.
