“…A two-dimensional lattice structure of dielectric rods, forming a photonic crystal, can address those issues while retaining the benefit of large detection volume at high frequencies. An auxetic behavior of rotating polygons, which enables isotropic expansion or contraction of the dielectric array in two dimensions, can be employed as a practical frequency tuning mechanism [39].…”

The axion offers a well-motivated solution to two fundamental questions in modern physics: the strong CP problem and the dark matter mystery. Cavity haloscopes, exploiting resonant enhancement of photon signals, provide the most sensitive searches for axion dark matter in the microwave region. However, current experimental sensitivities are limited to the O(100)μeV range, while recent theoretical predictions for the axion mass favor up to O(102)μeV, suggesting the need of new experimental approaches that are suitable for higher mass regions. CAPP has developed/proposed several haloscopes effective for high-mass axion searches based on new cavity concepts and practical tuning mechanisms. They are characterized by large detection volumes and/or high quality factors at high frequencies, achieved by partitioning a single cavity into multiple cells, exploiting higher-order resonant modes, and constructing dielectric photonic crystal structures. Improving on the dish antenna haloscope scheme, a horn antenna array has also been proposed for volume-efficient broadband search in the THz region. We review these haloscope designs for sensitive search in the high-mass regions and discuss their impacts on future experiments.

“…CAPP has produced a double-cell and 8-cell cavity, successfully adjusting the frequency in the 3.14−3.36 GHz and around 5.8 GHz regions, respectively, by placing a sapphire rod in each cell of the multi-cell cavity and rotating and moving it from the center of the cell to the wall separating the cells. Furthermore, CAPP developed a photonic crystal (PC) haloscope cavity to explore higher frequencies [286]. This cavity contains periodically arranged dielectric rods with low volume loss and high permittivity that act as independent cavities, forming a TM 010 -like mode, as illustrated in Fig.…”

“…Recently, CAPP launched CAPP-HF, a new initiative to explore high-frequency axions in a more diverse manner by incorporating a new 12 T/8 cm magnet into a dilution fridge. CAPP-HF aims to search for axions above 10 GHz by utilizing not only the existing technology of multiple-cell cavities but also the newly announced photonic crystal cavity [286] and single photon detection, which is currently being developed using the expertise available in Korea. CAPP-HF is expected to commence exploration of sub-10 GHz axions by 2023.…”

Feebly-interacting particles: FIPs 2020 workshop report

et al. 2021

With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader particle and astrophysics community for exploring the physics of light and feebly-interacting particles as a paradigm complementary to a New Physics sector at the TeV scale and beyond. FIPs 2020 has been the first workshop fully dedicated to the physics of feebly-interacting particles and was held virtually from 31 August to 4 September 2020. The workshop has gathered together experts from collider, beam dump, fixed target experiments, as well as from astrophysics, axions/ALPs searches, current/future neutrino experiments, and dark matter direct detection communities to discuss progress in experimental searches and underlying theory models for FIPs physics, and to enhance the cross-fertilisation across different fields. FIPs 2020 has been complemented by the topical workshop “Physics Beyond Colliders meets theory”, held at CERN from 7 June to 9 June 2020. This document presents the summary of the talks presented at the workshops and the outcome of the subsequent discussions held immediately after. It aims to provide a clear picture of this blooming field and proposes a few recommendations for the next round of experimental results.

Haloscopes, microwave resonant cavities utilized in detecting dark matter axions within powerful static magnetic fields, are pivotal in modern astrophysical research. This paper delves into the realm of cylindrical geometries, investigating techniques to augment volume and enhance compatibility with dipole or solenoid magnets. The study explores volume constraints in two categories of haloscope designs: those reliant on single cavities and those employing multicavities. In both categories, strategies to increase the expanse of elongated structures are elucidated. For multicavities, the optimization of space within magnets is explored through 1D configurations. Three subcavity stacking approaches are investigated, while the foray into 2D and 3D geometries lays the groundwork for future topological developments. The results underscore the efficacy of these methods, revealing substantial room for progress in cylindrical haloscope design. Notably, an elongated single cavity design attains a three-order magnitude increase in volume compared to a WC-109 standard waveguide-based single cavity. Diverse prototypes featuring single cavities, 1D, 2D, and 3D multicavities highlight the feasibility of leveraging these geometries to magnify the volume of tangible haloscope implementations.
