This work describes the operation of a High Frequency Gravitational Wave detector based on a cryogenic Bulk Acoustic Wave (BAW) cavity and reports observation of rare events during 153 days of operation over two separate experimental runs (Run 1 and Run 2). In both Run 1 and Run 2 two modes were simultaneously monitored. Across both runs, the 3rd overtone of the fast shear mode (3B) operating at 5.506 MHz was monitored, while in Run 1 the second mode was chosen to be the 5th OT of the slow shear mode (5C) operating at 8.392 MHz. However, in Run 2 the second mode was selected to be closer in frequency to the first mode, and chosen to be the 3rd overtone of the slow shear mode (3C) operating at 4.993 MHz. Two strong events were observed as transients responding to energy deposition within acoustic modes of the cavity. The first event occurred during Run 1 on the 12/05/2019 (UTC), and was observed in the 5.506 MHz mode, while the second mode at 8.392 MHz observed no event. During Run 2, a second event occurred on the 27/11/2019(UTC) and was observed by both modes. Timing of the events were checked against available environmental observations as well as data from other detectors. Various possibilities explaining the origins of the events are discussed.

“…Quartz has been extensively studied in optical a) Electronic mail: maxim.goryachev@uwa.edu.au domain using various methods such as Infrared Spectroscopy, dielectric relaxation spectroscopy and thermoluminesence 11 , etc. In contrast, microwave spectroscopy has been limited mostly to studies of natural quartz for geological purposes or intensionally doped or irradiated synthetic samples.…”

We report the observation of g-factors of natural paramagnetic impurities in a pure synthetic quartz crystal at milli-Kelvin temperatures. Measurements are made by performing spectroscopy using multiple high-Q Whispering Gallery Modes sustained in the crystal. Extreme sensitivity of the method at low temperatures allows the determination of natural residual impurities introduced during the crystal growth. We observe g-factors that significantly differ from integer multiples of the electron g-factor in vacuum, and with values of up to 7.6, which reveals much stronger coupling between impurities and the crystal lattice than in previous studies. Both substitutional and interstitial ions are proposed as candidates for the observed interactions.Crystalline quartz is very important material extensively used in different areas of science and technology including optics, acoustics and device physics. In particular, unprecedented acoustic quality factors both at liquid helium and milli-Kelvin temperatures have been recently demonstrated 1-3 . To further progress these areas, ultra-pure materials are required, which depend on efficient refining and identification of residual impurities. These impurities are believed to be responsible for limitations in quality factors 4 and generation of the flicker noise as well as nonlinear effects at low temperatures 5 . In addition to applications of quartz itself, this material serves as a case study for understanding different defects in other silica-based materials.Quartz is one of the most widely used materials due to its exceptional purity. This originates in the stable atomic configuration, which allows only few elements from the periodic table to be present in the quartz crystalline structure as an impurity 6 . Nevertheless, the Electron Paramagnetic Resonance (EPR) studies of this material are relatively easy due to the very narrow linewidths which increase the method sensitivity. Very narrow linewidths are explained by the fact that none of the host constitutive nuclei (most abundent isotopes) have a spin moment 7 . This makes quartz crystal a good candidate as a host material for Cavity Quantum Electrodynamics experiments, which interact spin ensemble impurities to microwave frequency photons 8,9 .The imperfection of quartz crystals are related to substitutional and interstitial impurity ions (Al, H, Cu, Ag, Ge, P, Ti, Fe, etc) as well as vacancy centres (E ) associated with oxygen ions missing in the crystal structure. Trivalent substitutional ions such as Al 3+ , Fe 3+ , Ge 3+ and Ti 3+ are typically accompanied by monovalent impurity ions, such as H + , Li + , Na + , which are interstitially positioned in the crystal as charge compensators. There is a large number of experimental and theoretical studies dedicated to different representatives of these impurities and corresponding bonds 6,7,10 . domain using various methods such as Infrared Spectroscopy, dielectric relaxation spectroscopy and thermoluminesence 11 , etc. In contrast, microwave spectroscopy has been limited mo...

“…In particular, it demonstrates that impurities can significantly limit the cavity performance even at relatively modest level of quality factor. We have demonstrated effects of strong impurity-phonon coupling never observed before, which inevitably leads to a better understanding of impurities in crystal in solids 23 and their interaction with acoustical waves 24 .…”

We demonstrate a variety of nonlinear phenomena at extremely low powers in cryogenic acoustic cavities fabricated from quartz material, which have not undergone any electrodiffusion processes. Nonlinear phenomena observed include lineshape discontinuities, power response discontinuities, quadrature oscillations and selfinduced transparency. These phenomena are attributed to nonlinear dissipation through a large number of randomly distributed heavy trapped ions, which would normally be removed by electrodiffusion. A simple mean-field model predicts most of the observed phenomena. In contrast to Duffing-like systems, this system shows an unusual mechanism of nonlinearity, which is not related to crystal anharmonisity. arXiv:1309.5230v1 [cond-mat.dis-nn]
