Since its inception, the field of Advanced Accelerators has regarded future particle-physics colliders as the ultimate application of > 1 GV/m accelerator technology. Over the last decades, rapid experimental and theoretical progress [1,2,3] drove a conceptual evolution of potential future colliders based on Wakefield Accelerator (WFA) technology. The recent P5 Report [4] calls for “vigorous...

We quantify the physics potential of various beam configurations for 10 TeV wakefield colliders, including the impact of beam-beam interactions. We study e+e- and e-e- colliders with round and flat beams, as well as a \gamma\gamma collider. Though large beam-beam interactions tend to increase the Standard Model backgrounds, we find that these backgrounds can usually be mitigated on the...

Laser-driven plasma accelerators have demonstrated single-stage acceleration of electron beams up to 10 GeV over tens of cm, and these compact laser-plasma accelerating structures offer 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...

Structure-wakefield acceleration (SWFA) presents a promising route to a multi-TeV linear collider by combining GV/m-class gradients with high wall-plug efficiency and components suitable for industrial-scale production. In SWFA, a high-charge drive beam excites wakefields in engineered solid-state structures to accelerate a low-emittance “main” beam. Prospective collider configurations are...

The 10 TeV Wakefield Collider Design Study [1] aims to produce a self-consistent, start-to-end design of a 10 TeV-center-of-mass linear collider based on wakefields technology. One of the considered options for driving the main linac is beam-driven plasma wakefield acceleration (PWFA). The goal of the PWFA-Linac Working Group is to identify the main challenges and showstoppers, and to define a...

Dielectric laser acceleration (DLA) applies well-known concepts of structure-based accelerators at a microscopic length scale by driving dielectric structures with strong infrared femtosecond laser pulses [1]. In DLA, the optical electro-magnetic fields take the role of the microwave fields, and the transparent dielectric structures shape the field, similar to the microwave structures in RF...

Solid-state plasma wakefield acceleration has recently attracted attention as a novel method for achieving unprecedented ultra-high acceleration gradients on the order of 1 TV/m or beyond. In this context, recent advancements in nanofabrication techniques have opened up the possibility of creating structured plasmas with tailored properties. For instance, the utilization of carbon nanotube...

Plasma-based acceleration offers a promising pathway toward compact, high-gradient accelerators for next-generation particle colliders and advanced light sources. While substantial progress has been achieved for electron beams, the production of collider-quality positron beams remains a formidable challenge. This presentation will outline the stringent beam-quality requirements for future...

Current hadron accelerators can deliver energies far beyond those of lepton acceleration schemes, but this energy is divided among the partons. Plasma wakefield acceleration offers a method to transfer energy from a drive beam to a witness, allowing existing proton accelerators to be transformed into lepton machines. Relatively little civil engineering would be required due to the high...

Simulating entire beamlines for future linear colliders remains a significant challenge due to the diversity of components and the wide range of physical effects that must be accurately modelled. This is particularly true for colliders based on advanced accelerator concepts such as plasma acceleration. The Adaptable Beginning-to-End Linac (ABEL) simulation framework employs a modular...

Plasma-wakefield acceleration holds great promise for particle physics due to its orders-of-magnitude higher accelerating gradients, which can result in significant cost reductions based on a sizeable reduction in footprint. However, plasma-based acceleration of positrons—required for an electron-positron collider—is much more difficult than for electrons. In 2023 a novel collider scheme,...

Recent experiments in short-pulse structure-wakefield acceleration (SWFA) have shown that nanosecond-scale RF drive pulses can sustain unprecedented gradients while mitigating breakdown probability compared with conventional long-pulse operation. Building on studies at the Argonne Wakefield Accelerator (AWA), we report results on high-gradient performance, RF breakdown behavior, and dark...

Plasma accelerators can accelerate electron bunches in fields exceeding 1 GV/m, making them a promising technology to greatly reduce the footprint of future linear colliders. In this scheme, a dense electron bunch drives a charge density wave in the plasma. The strong fields of this ‘wakefield’ are used to accelerate a trailing bunch. Fundamental research on this scheme is performed at the...

The EuPRAXIA@SPARC_LAB facility is the beam-driven pillar of the EuPRAXIA project, which aims to establish by the end of 2031 the first European Research Infrastructure dedicated to plasma-based accelerators. The facility is expected to demonstrate the usability of such accelerators to deliver high-brightness electron beams in the 1–5 GeV range for a broad user community.

Recently, a high energy superconducting (SC) e+e− linear collider with energy recovery (ERLC) has been proposed, which uses twin RF structures to avoid parasitic collisions inside linacs. Such a collider can operate in a duty cycle (DC) or continuous (CW) modes (if sufficient power is available) with a luminosity of about 10^36) cm^−2 s^−1 at 2E_0 = 250−500 GeV. In this presentation I will...

The Ghost Collider is an innovative proposal for a 550 GeV center-of-mass, 275 GeV per beam linear collider with four interaction regions, each with the design luminosity. The primary innovation is the use of “ghost bunches” containing equal numbers of electrons and positrons so they are electrically neutral. In the linacs, energy is transferred between electrons and positrons in the same...
