The HALHF concept utilises beam-driven plasma-wakefield acceleration to accelerate electrons to very high energy and collide them with much lower-energy positrons accelerated in a conventional RF linac. This idea, which avoids difficulties in the plasma acceleration of positrons, has been used to design a Higgs factory that is much smaller, cheaper, and greener than any based solely on...
After the program of Higgs boson physics at a linear collider is completed, we expect that the long, straight tunnel can be used with advanced acceleration methods, such as plasma wakefield, to create a higher-energy collider in the 10's of TeV CM region. This might be an e+e- or a γγ collider. (Circular) muon colliders are also discussed for this energy regime. I will discuss the physics...
There is growing interest in the gamma-gamma configurations of multi-TeV PWFA colliders since they do not require positrons or flat beams and may have the same particle physics potential as multi-TeV electron positron or muon anti-muon colliders. In this report the CAIN Monte Carlo is used to study the luminosity spectra of several gamma-gamma configurations assuming a round beam 15 TeV...
A Higgs Factory is considered the highest priority next collider project by the high-energy physics community. Very advanced designs based on radio-frequency cavities exist, and variations on this approach are still being developed. Recently, also an option based on electron-bunch driven plasma wakefield acceleration has been proposed. In this article, we discuss a further option based on...
Characterizing the beam-plasma interaction in the plasma wakefield accelerator, an essential ingredient for a potential linear collider or free-electron laser represents a significant challenge for experimental measurements. The typical dimensions involved in such diagnostic systems are below one micron, with attendant femtosecond time-resolution. Further, the plasma environment and the beam...
Laser-driven plasma accelerators have demonstrated ultra-high accelerating gradients, offering the potential to reduce the size and cost of a future energy-frontier linear collider. In this presentation, I will discuss the design considerations for the application of laser-driven plasma-based accelerator technology to a multi-TeV linear collider. Plasma accelerators naturally accelerate...
Plasma accelerators sustain large field gradients and could enable future x-ray sources and compact linear colliders. The development of performant open-source simulation methods allows for the investigation of open challenges towards these applications, including the acceleration of beams with high quality to high energies. This presentation will discuss recent studies on these topics....
Research and development on novel structures is at the core of advancing structure wakefield acceleration (SWFA), and is critical to future AAC-based linear colliders. In this talk, I will present recent progress on the R&D of advanced radiofrequency (RF) structures for Structure Wakefield Acceleration, metamaterial structures, and sub-terahertz structures. The experiments were performed at...
Our research group, composed of Pohang Accelerator Laboratory, Korea University, Northen Illinois Universiy, and Argonne Wakefield Accelerator Facility, is researching on wakefields generated in corrugated structures. Main goal of our research is to make several applications such as a THz source in the GW scale, wakefield accelerators and IR-FELs.
As a first step, we designed and fabricated...
This talk presents the latest developments in beam delivery systems (BDS) for the Compact Linear Collider (CLIC) and their applications in plasma colliders. The CLIC's BDS has undergone significant refinements to address challenges in minimizing beam size, correcting chromatic aberrations, and maintaining stability at high energies (380 GeV and 3 TeV). Key innovations include the integration...
The next generation electron-positron collider is crucial for precision measurements of the Higgs boson and exploring new physics beyond the Standard Model. Currently, the scale and cost of linear or circular colliders based on traditional radio-frequency accelerators are enormous to meet the standards for a Higgs factory. Advanced accelerator concepts such as the plasma wakefield accelerator...
