Magnetic wideband VHF localized field probe using magnon polaritons
Gabriel Soares, Nicolò Crescini, Giovanni Carugno +1
We present here an optimisation and demonstration of a wide band instrument capable of measuring localised and directionally alternated magnetic fields below pT in the very high fr…
An Haloscope Amplification Chain based on a Travelling Wave Parametric Amplifier
Caterina Braggio, Giulio Cappelli, Giovanni Carugno +8
In this paper we will describe the characterisation of a rf detection chain based on a travelling wave parametric amplifier (TWPA). The detection chain is meant to be used for dark…
A high-Q microwave dielectric resonator for axion dark matter haloscopes
R. Di Vora, D. Alesini, C. Braggio +17
The frequency band 1-15 GHz provides exciting prospects for resonant axion haloscopes as indicated by cosmological and astrophysical arguments. Among the challenges currently addre…
Phase-modulated cavity magnon polaritons as a precise magnetic field probe
Nicolò Crescini, Giovanni Carugno, Giuseppe Ruoso
We describe and operate a novel spin-magnetometer based on the phase modulation of cavity magnon polaritons. In this scheme a rf magnetic field is detected through the sidebands it…
Realization of a high quality factor resonator with hollow dielectric cylinders for axion searches
D. Alesini, C. Braggio, G. Carugno +18
The realization and characterization of a high quality factor resonator composed of two hollow-dielectric cylinders with its pseudo-TM mode resonating at 10.9 GHz frequency…
High quality factor photonic cavity for dark matter axion searches
D. Alesini, C. Braggio, G. Carugno +18
Searches for dark matter axion involve the use of microwave resonant cavities operating in a strong magnetic field. Detector sensitivity is directly related to the cavity quality f…
Galactic axions search with a superconducting resonant cavity
D. Alesini, C. Braggio, G. Carugno +22
To account for the dark matter content in our Universe, post-inflationary scenarios predict for the QCD axion a mass in the range $(10-10^3)\,μ\mbox{eV}$. Searches with haloscope e…
The Klash Proposal: Status and Perspectives
C. Gatti, D. Alesini, D. Babusci +12
Recently some of the authors proposed a search for galactic axions with mass about 0.2~eV using a large volume resonant cavity, tens of cubic meters, cooled down to 4~K and imme…
Microwave cavity tuned with liquid metal and its application to Electron Paramagnetic Resonance
C. S. Gallo, E. Berto, C. Braggio +6
This note presents a method to tune the resonant frequency of a rectangular microwave cavity. This is achieved using a liquid metal, GaInSn, to decrease the volume of the c…
Searching for galactic axions through magnetized media: QUAX status report
G. Ruoso, D. Alesini, C. Braggio +15
The current status of the QUAX R\&D program is presented. QUAX is a feasibility study for a detection of axion as dark matter based on the coupling to the electrons. The relevant s…
The QUAX-g_p g_s experiment to search for monopole-dipole Axion interaction
Nicolò Crescini, Caterina Braggio, Giovanni Carugno +3
The QCD axion is an hypothetical particle introduced to solve the strong CP problem of standard model of particle physics and is of interest as a possible component of cold dark ma…
