Experimental Search for Solar Axions
نویسندگان
چکیده
A new technique has been used to search for solar axions using a single crystal germanium detector. It exploits the coherent conversion of axions into photons when their angle of incidence satisfies a Bragg condition with a crystalline plane. The analysis of approximately 1.94 kg.yr of data from the 1 kg DEMOS detector in Sierra Grande, Argentina, yields a new laboratory bound on axion-photon coupling of gaγγ < 2.7 × 10 −9 GeV −1 , independent of axion mass up to ∼ 1 keV.

A proposal to search for a monochromatic component of solar axions using Fe
A new experimental scheme is proposed to search for almost monochromatic solar axions, whose existence has not been discussed heretofore. The axions would be produced when thermally excited Fe in the sun relaxes to its ground state and could be detected via resonant excitation of the same nuclide in a laboratory. A detailed calculation shows that the rate of the excitation is up to order 10 eve...
متن کاملA Search for the Resonant Absorption of Solar Axions by Atomic Nuclei
A search for resonant absorption of solar axions by Fe and Tm targets was performed. The Si(Li) detector placed inside a low-background setup was used to detect the γ-quanta appearing from the de-excitation of the low-lying nuclear levels of Fe and Tm (14.4 keV and 8.41 keV correspondingly): A+Ntarget → N∗ target +γ. The obtained data allowed us to set the new upper limits on the axion mass val...

The CDMS-II experiment operates 19 germanium detectors with a mass of 250g each in a very low background environment. Originally designed for the search for Dark Matter the experiment can also detect solar axions by Primakoff conversion to photons. The Bragg condition for Xray momentum transfer in a crystal allows for coherent amplification of the Primakoff process. Since the orientation of the...

متن کاملSearch for sub-electronvolt solar axions using coherent conversion of axions into photons in magnetic field and gas helium
A search for solar axions has been performed using an axion helioscope which is equipped with a 2.3m-long 4T superconducting magnet, PIN-photodiode X-ray detectors, and a telescope mount mechanism to track the sun. In addition, a gas container to hold dispersion-matching gas has been developed and a mass region up to ma = 0.27 eV was newly explored. From the absence of any evidence, analysis se...
