Laser-plasma accelerators are capable of sustaining accelerating fields of 10–100 GeV/m, 100–1000 times that of conventional technology and the highest fields produced by any of the widely researched advanced accelerator concepts. Laser-plasma accelerators also intrinsically accelerate short particle bunches, several orders of magnitude shorter than that of conventional technology, which leads to reductions in beamstrahlung and, hence, savings in the overall power consumption to reach a desired luminosity. These properties make laser-plasma accelerators a promising accelerator technology for a more compact, less expensive high-energy linear collider providing multi-TeV polarized leptons. In this submission to the Snowmass 2021 Accelerator Frontier, we discuss the motivation for a laser-plasma-accelerator-based linear collider, the status of the field, and potential linear collider concepts up to 15 TeV. We outline the research and development path toward a collider based on laser-plasma accelerator technology, and highlight near-term and mid-term applications of this technology on the collider development path. The required experimental facilities to carry out this research are described. We conclude with community recommendations developed during Snowmass.

“…Several groups have demonstrated femtosecond Cr2+:ZnSe CPAs at kHz repetition rate with pulse energy approaching 10 millĳoule-level [102,112,119].The microsecond-level upper state lifetime of Cr:ZnSe indicates that ns lasers for CPA pumping synchronized to the seed pulses are required. Recently proposed and demonstrated directly diode pumped Big Aperture Thulium (BAT) laser concept enabling ns multi-joule-level systems operating near maximum of Cr:ZnSe absorption band at ∼ 1.9 μm at average powers approaching 100 kW [48,120]. Ultrafast Cr:ZnS(Se) seed lasers in combination with BAT pumped Cr:ZnSe CPA spinning ring architecture is a clear route to reach high-average power and high-peak power MWIR pulses.…”

Large scale laser facilities are needed to advance the energy frontier in high energy physics and accelerator physics. Laser plasma accelerators are core to advanced accelerator concepts aimed at reaching TeV electron electron colliders. In these facilities, intense laser pulses drive plasmas and are used to accelerate electrons to high energies in remarkably short distances. A laser plasma accelerator could in principle reach high energies with an accelerating length that is 1000 times shorter than in conventional RF based accelerators. Notionally, laser driven particle beam energies could scale beyond state of the art conventional accelerators. LPAs have produced multi GeV electron beams in about 20 cm with relative energy spread of about 2 percent, supported by highly developed laser technology. This validates key elements of the US DOE strategy for such accelerators to enable future colliders but extending best results to date to a TeV collider will require lasers with higher average power. While the per pulse energies envisioned for laser driven colliders are achievable with current lasers, low laser repetition rates limit potential collider luminosity. Applications will require rates of kHz to tens of kHz at Joules of energy and high efficiency, and a collider would require about 100 such stages, a leap from current Hz class LPAs. This represents a challenging 1000 fold increase in laser repetition rates beyond current state of the art. This whitepaper describes current research and outlook for candidate laser systems as well as the accompanying broadband and high damage threshold optics needed for driving future advanced accelerators.

Laser-plasma accelerators (LPAs) are capable of sustaining accelerating fields of 1-100 GeV/m, 10-1000 times that of conventional RF technology, and the highest fields produced by any of the widely researched advanced accelerator concepts. Furthermore, LPAs intrinsically produce short particle bunches, 100-1000 times shorter than that of conventional RF technology, which leads to reductions in beamstrahlung and savings in overall power consumption. Furthermore, they enable novel energy recovering methods that can reduce power consumption and improve the luminosity per unit energy consumption for linear colliders. These properties make LPAs a promising candidate as drivers for a more compact, less expensive high-energy collider by providing multi-TeV polarized leptons in a relatively short distance ∼1 km. Collider concepts are discussed up to the 15 TeV range. A future RF-based linear collider facility could be re-purposed to delivery higher energies with LPA technology thereby extending physics reach while saving on construction costs.Previous reports have made strong recommendations for a vigorous program on LPA R&D and applications, including the previous P5 and subcommittee reports, the European Strategy and Laboratory Directors Group reports, and several others. Numerous significant results have been obtained since the last P5 report, including the production of high quality electron bunches at 8 GeV from a single stage, the staging of two LPA modules, novel injection techniques for ultra-high beam brightness, investigation of processes that stabilize beam break up, new concepts for positron acceleration, and new technologies for high-average-power, high-efficiency lasers. In addition to the long term goal of a high energy collider, LPAs can provide compact sources of particles and photons for a wide variety of near-term applications in science, medicine, and industry.Research on LPAs has exploded in recent years, driven in part by the extremely rapid advances made in high-power lasers based on the 2018 Nobel Prize winning technique of chirped-pulse amplification. Numerous high-power laser facilities have sprung up worldwide, particularly in Europe and Asia. Consequently, about 800-1000 research papers are published annually on LPAs. Since much of this research is overseas, it is critical that the U.S. make strong investments in LPAs to ensure global leadership.The LPA community proposes the following recommendations to the Snowmass conveners:1. Vigorous research on LPAs, including experimental, theoretical, and computational components, continue as part of the General Accelerator R&D program to make rapid progress along the LPA R&D roadmap towards an eventual high energy collider, develop intermediate applications, and ensure international competitiveness.2. Enhance R&D on laser drivers to develop the efficient, high repetition rate, high average power laser technology that will power LPA colliders.3. Near-term LPA capability extensions should be carried out, such as enhancing existing facilities in laser pe...
