Axions are a leading dark matter candidate, and may be detected by their resonant conversion to a monochromatic RF signal in a tunable microwave cavity permeated by a strong magnetic field. The Axion Dark Matter eXperiment – High Frequency (ADMX-HF) serves both as a innovation platform for cavity and amplifier technologies for the microwave cavity axion experiment, and as a pathfinder for a...

Axions are a natural consequence of the Peccei-Quinn mechanism, the most compelling solution to the strong-CP problem. Similar axion-like particles (ALPs) also appear in a number of possible extensions of the Standard Model, notably in string theories. Both axions and ALPs are very well motivated candidates for the Dark Matter, and in addition would be copiously produced at the sun’s interior....
Prof. Budker Dmitry (Helmholtz Institute Mainz)
Axions, axion-like particles (ALPs), dilatons, and other ultralight (masses from 10-4 down to 10-23 eV) particles have been discussed as possible candidates for dark matter. An interesting feature of these ideas is that they lead to predictions of potentially observable transient and oscillating effects. I will describe how we are looking for these as well as the relation of such experiments...

The Axion Dark Matter eXperiment (ADMX) is a cavity haloscope search for dark matter axions. The Gen 2 version ADMX has the goal of being sensitive to even the pessimistically coupled axions in the well motivated 1-10 GHz frequency region. This will be a significant improvement over previous cavity searches, and have a good chance of discovering the axion, or ruling out an interesting...

The CAST-CAPP/IBS experiment is a joint effort between the CERN Axion Solar Telescope (CAST) collaboration  and the Center for Axion and Precision Physics Research (CAPP/IBS) , searching for cold dark matter axions. In this project, tunable rectangular cavities are inserted in the 9T CAST dipole magnet, an LHC prototype, at CERN. The traditional haloscope technique suggested by...

The Large Underground Xenon (LUX) experiment is a 350 kg liquid xenon time projection chamber (TPC) designed to directly detect galactic dark matter. Xenon detectors present suitable features to detect dark matter candidates other than WIMPs, such as axions, because of the extremely low radioactivity background for electronic recoils they can provide. LUX can probe both axions coming from...
Dr. Woohyun Chung (CAPP/IBS)
The main research focus of the IBS Center for Axion and Precision Physics Research (CAPP) is to establish a state-of-the-art axion experiment in Korea and to search for relic axion particles converting to microwave photons in a resonant cavity submerged in a strong magnetic field. The initial stage of building our axion experiment, CULTASK (CAPP Ultra Low Temperature Axion Search in Korea) is...
Prof. David Tanner (University of Florida)
The Axion Dark Matter eXperiment (ADMX) is conducting a search for dark-matter axions trapped in the halo of the Milky Way Galaxy. Axions, originally postulated to solve the strong CP problem in particle physics, would have been created as cold (non-relativistic) very weakly interacting particles in the early stages of the expansion of the universe. If their mass is in the range 2 to 50...

The International Axion Observatory (IAXO) is a proposed 4th generation axion helioscope that will look for axions and ALPs originating in the Sun via the Primakoff conversion of the solar plasma photons. The baseline detection technique for IAXO are ultra-low background Time Projection Chambers (TPC) with a thin window for the entrance of x-rays and pixelated Micromegas readout, manufactured...
Prof. Andrew Geraci (University of Nevada Reno)
The Axion Resonant InterAction Detection Experiment (ARIADNE) is a collaborative effort to search for short-range spin-dependent couplings between nuclei resulting from the QCD axion, using a technique based on nuclear magnetic resonance. The aim is to detect monopole-dipole interactions between the spin of 3He nuclei and a rotating unpolarized tungsten attractor. I will discuss the basic...
127. Commissioning of the Generation-2 Axion Dark Matter eXperiment (ADMX) with near quantum noise limited amplifiers
Dr. Rakshya Khatiwada (University of Washington)
University of Washington, ADMX uses the most sensitive microwave receiver in the world to look for QCD Axions that convert into microwave photons in the presence of a strong magnetic field. Axion is also a compelling cold dark matter candidate. ADMX is starting its Generation-2 run in the summer of 2016 with upgrades including a dilution refrigerator and tunable quantum noise limited...
Prof. Asimina Arvanitaki (Perimeter Institute)
The QCD axion has been proposed more than 30 years ago to explain the smallness of the neutron's dipole moment. It is an excellent Dark Matter candidate and the search for it has been ongoing ever since its conception. In my talk I will describe two experiments that will explore complementary parts of the axion's parameter space. When the axion's Compton wavelength is tens of microns up...
Prof. Richard Creswick (University of South Carolina)
Axions coupled to quarks can be produced in the solar core by the decay of thermally excited nuclear states. Here we consider 14.4 keV axions from Fe-56 detected by coherent Bragg-Primakoff conversion to x-rays in crystals. The locus of points that satisfy the Bragg condition lie on a set of circles, one for each reciprocal vector, on the celestial sphere, and as the path of the Sun crosses...
Dr. Mikhail Karnevskiy (DESY)
I will present the status of the ALPS2 experiment, a new search for axion-like particles that builds upon the successes of the original ALPS experiment and increase projected sensitivity to new physics by 3 orders of magnitude.

Light shining through a wall experiments can be used to make measurements of photon-WISP couplings. The first stage of the CASCADE experiment at the Cockcroft Institute of Accelerator Science and Technology is intended to be a proof-of-principle experiment utilising standard microwave technologies to make a modular, cryogenic HSP detector to take advantage of future high-power superconducting...

Light pseudo-Nambu-Goldstone bosons (pNGBs) such as, e.g. axion-like particles, that are non-thermally produced via the misalignment mechanism are promising dark matter candidates. An important feature of pNGBs is their periodic potential, whose scale of periodicity controls all their couplings. As a consequence of the periodicity the maximal potential energy is limited and, hence, producing...
