SWFA (structure wakefield accelerator) provides a viable approach to the TeV class linear collider, but significant challenges remain. The recent P5 report recommended development of a wakefield technology based 10TeV collider design in next 5 years. In this presentation, the current status of SWFA for LC will be presented. The potential contribution of SWFA technologies to the unified...
In this presentations we will review the design approaches for Beam Delivery and Machine Detector Interface for advanced colliders, starting from designs of classical colliders, and discussing what design assumptions need to be revisited and how, in order to arrive to an optimal design suitable for next generation concepts.
In this talk we will consider possible pathways for the upgrade of a linear Higgs factory to High Energy.
This talk will cover proposals for beam driven, plasma-based (PWFA) colliders both past and present. It will cover the proposed systems and future work as written. It will also review community feedback and challenges, some unique to PWFA. The goal is a high degree of audience discussion of the status of PWFA and the road to a collider.
The successful operation of future e+ e- linear colliders (LC) critically relies on the ability to tightly focus beams at the interaction point to achieve high luminosities. With spot sizes expected to reach the nanometer scale in TeV LC, traditional beam delivery systems face challenges due to chromatic effects and the requirement of small emittance. To overcome these challenges, the concept...
Research is in progress to develop high efficiency RF sources for driving accelerators and colliders. These include a 350-450 MHz multiple beam triode, a single beam klystron at L-Band, and a multiple beam klystron at C-Band. The goal efficiency for these devices is 80% or better.
A single beam klystron estimated to operate at 80% has been built and is awaiting testing. The klystron uses a...
High intensity laser facilities are expanding their scope from laser and particle-acceleration test beds to user facilities and nuclear physics experiments. A basic goal is to confirm long-standing predictions of strong-field quantum electrodynamics, but with the advent of high-repetition rate laser experiments producing GeV-scale electrons and photons, novel searches for new high-energy...
Plasma acceleration has emerged as a promising technology for future particle accelerators, particularly linear colliders. Significant progress has been made in recent decades toward high-efficiency and high-quality acceleration of electrons in plasmas. However, this progress does not generalize to the acceleration of positrons, as plasmas are inherently charge asymmetric. Here, we present a...
Kinetic simulations of relativistic, charged particle beams and advanced plasma accelerator elements are often performed with high-fidelity particle-in-cell simulations, some of which fill the largest GPU supercomputers. Self-consistent modeling of wakefield accelerators for colliders includes many elements beyond plasma acceleration. The integrated Beam, Plasma & Accelerator Simulation...
