“…Making the existing particle accelerator modeling ecosystem compatible and interdependent will be beneficial towards the goal of predictive start-to-end modeling [30]. As a community, we should expect and ready models and codes for the exploration of "hybrid" accelerators, with conventional and advanced elements, as the next step for advanced accelerator modeling.…”

Developing complex, reliable advanced accelerators requires a coordinated, extensible, and comprehensive approach in modeling, from source to the end of beam lifetime. We present highlights in Exascale Computing to scale accelerator modeling software to the requirements set for contemporary science drivers. In particular, we present the first laser-plasma modeling on an exaflop supercomputer using the US DOE Exascale Computing Project WarpX. Leveraging developments for Exascale, the new DOE SCIDAC-5 Consortium for Advanced Modeling of Particle Accelerators (CAMPA) will advance numerical algorithms and accelerate community modeling codes in a cohesive manner: from beam source, over energy boost, transport, injection, storage, to application or interaction. Such start-to-end modeling will enable the exploration of hybrid accelerators, with conventional and advanced elements, as the next step for advanced accelerator modeling. Following open community standards, we seed an open ecosystem of codes that can be readily combined with each other and machine learning frameworks. These will cover ultrafast to ultraprecise modeling for future hybrid accelerator design, even enabling virtual test stands and twins of accelerators that can be used in operations.

“…Development of enhanced modeling capabilities is required in order to guide the R&D effort towards a TeV collider. The numerical modeling, in 3D, of LPAs using conventional Particle-In-Cell (PIC) codes is a computationally challenging task [89]. This is due to the great disparity among the length scales involved in the simulation, ranging from the micron scale of the laser wavelength (e.g., electron quivering in the laser field) to the meter scale of the laser-plasma interaction length for a multi-GeV-class LPA stage.…”

“…In addition to kinetic modeling, development of fast machine learning tools should be addressed and such instruments used to guide large-scale parameter scans and to help control the laser plasma accelerator [89,100,101]. Furthermore, in order to perform an end-to-end modeling of the collider, it is desirable to integrate into the simulations physics models that go beyond conventional kinetic laser-plasma physics description.…”

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...

“…The importance of particle accelerators to society, along with their increasing complexity and the high cost of new accelerator facilities, demand that the most advanced computing and ML/AI tools be brought to bear on R&D activities in particle beam and accelerator science [1,2]. Pushing the limits in beam intensity, quality and control demands more accurate, more complete and faster predictive tools, with an ultimate goal of virtual accelerators.…”

Accelerator and beam physics (ABP) is the science of the motion, generation, acceleration, manipulation, prediction, observation and use of charged particle beams. It focuses on fundamental long-term accelerator and beam physics research and development. Accelerator and beam physics research has resulted in important advances in accelerator science, yet support for this research is declining. NSF has terminated its program in Accelerator Science and funding by DOE through GARD and Accelerator Stewardship has been steady or declining. The declining support for accelerator research will slow advances and threaten student training and work-force development in accelerator science. We propose a robust and scientifically challenging program in accelerator and beam physics, which will position the field of US High Energy Physics to be productive and competitive for decades to come.
