“…Although it is often assumed that RF sources are "established," the truth is the current state of the art is nowhere near what the high energy physics community needs regarding cost/capability. Solving this enormous physics and engineering problem will require significant support for both computational and experimental R&D efforts in RF sources [6]. A real solution demands that we fundamentally re-imagine RF source topologies and rigorously attack the many exciting basic questions that arise from this challenge.…”

The high power RF system will be a significant budgetary driver for any future collider. An orderof-magnitude improvement in cost/capability is needed, and as a result, a robust R&D program in next-generation, economical RF sources is essential. In this paper, we discuss the challenges and opportunities that arise from advancing the state of the art in these devices. Specifically, research initiatives in new circuit topologies, advanced manufacturing techniques, and novel alternatives to conventional RF source components are discussed.

“…Further R&D aims for 50 MV/m gradients in 1.3 GHz structures [44]. An active ongoing accelerator R&D program for future multi-MW proton beams includes development of more efficient power supplies with capacitive energy storage and recovery, more economical RF power sources such as 80% efficient klystrons, magnetrons, and solid-state RF sources (compared to current ~55%) see for example [45,46].…”

For over half a century, high-energy particle accelerators have been a major enabling technology for particle and nuclear physics research as well as sources of X-rays for photon science research in material science, chemistry and biology. Particle accelerators for energy and intensity Frontier research in particle and nuclear physics continuously push the accelerator community to invent ways to increase the energy and improve the performance of accelerators, reduce their cost, and make them more power efficient. The accelerator community has demonstrated imagination and creativity in developing a plethora of future accelerator ideas and proposals. The technical maturity of the proposed facilities ranges from shovel-ready to those that are still largely conceptual. At this time, over 100 contributed papers have been submitted to the Accelerator Frontier of the US particle physics decadal community planning exercise known as Snowmass’2021. These papers cover a broad spectrum of topics: beam physics and accelerator education, accelerators for neutrinos, colliders for Electroweak/Higgs studies and multi-TeV energies, accelerators for Physics Beyond Colliders and rare processes, advanced accelerator concepts, and accelerator technology for Radio Frequency cavities (RF), magnets, targets and sources. This paper provides an overview of the present state of accelerators for particle physics and gives a brief description of some of the major facilities that have been proposed, their perceived advantages and some of the remaining challenges.

“…Figure 6 shows a 3D model of the proposed C-band (5.712 GHz) structure and magnitude of electric and magnetic field in the accelerating cell. While this structure is relatively complex, it was demonstrated that it could be machined in two halves (or four quarters) by a CNC milling machine [44]. This fabrication process provides ultra-high-vacuum (UHV) quality surfaces that need no further finishing apart from a standard copper surface etch.…”

“…Incorporating periodic permanent magnet focusing can further reduce fabrication and operation costs. Another approach is to develop a simple modular system that would combine power of several low-voltage, highly efficient klystrons [44,67].…”

Particle colliders remain indispensable scientific instruments to discover and study new elementary particles and fundamental forces of nature. Whether the collider is a factory (used to improve precision of measuring properties of already discovered particles or to enable studies of rare decay channels), an energy frontier machine (aimed at discovering new particles and forces), a heavy ion collider (allowing studies of what the universe looked like in the early moments after its creation), or an electron-hadron collider (where electrons are used for probing heavy ions or protons to study the fundamental force binding all visible matter), the radio frequency technologies play a key role in enabling the machine to reach its goals. This article considers challenges presented to the radio frequency technologies by the next generation of particle colliders and reviews R&D approaches and directions to address these challenges.
