Title: C-band high gradient research and facilities at Los Alamos National Laboratory
Abstract: This presentation will talk about two C-band test facilities at Los Alamos National Laboratory (LANL): C-band Engineering Research Facility in New Mexico (CERF-NM), and Cathodes and Rf Interactions in Extremes (CARIE). Modern applications such as X-ray sources require accelerators with optimized cost of construction and operation, naturally calling for high-gradient acceleration. At LANL we commissioned a high gradient test stand powered by a 50 MW, 5.712 GHz Canon klystron. The test stand is capable of conditioning accelerating cavities for operation at surface electric fields in excess of 300 MV/m. CERF-NM is the first high gradient C-band test facility in the United States. CERF-NM was fully commissioned in 2021. The construction of CARIE began in October of 2022. CARIE will house a high gradient copper RF photoinjector with a cathode insert for testing high quantum-efficiency photocathodes at high accelerating gradients.  The construction of CARIE is currently in process with another Canon klystron being installed and conditioned, followed by a high power C-band circulator, and a waveguide line. The all-copper RF photoinjector has been fabricated and will be installed this Spring. The injector with a cathode insert has been designed and is currently in fabrication.

Title: Plasma Based Accelerators for Ultra High Energy Colliders
Abstract: Recent experiments at SLAC demonstrated beam-driven plasma acceleration with accelerating gradients in excess of 150 GeV/m. That’s nearly 10,000 times the accelerating gradient produced by RF cavities in the SLAC linac. Wakefield accelerators are a promising technology for future high energy colliders and were identified by the P5 Panel as a path toward 10 TeV collisions. The US 10 TeV Wakefield Collider Design Study is currently being formed in response to P5’s recommendation. In this talk, I’ll discuss challenges and R&D opportunities for a 10 TeV Wakefield Collider, and highlight opportunities for engagement with HEP theorists and experimentalists. I will also explain how the 10 TeV Wakefield Collider Design Study fits into the broader future collider strategy, and how research towards a 10 TeV Wakefield Collider benefits near-term Higgs Factories.
