First results with the ORPHEUS dark matter detector
K. Borer, G. Czapek, F. Hasenbalg +8
The ORPHEUS dark matter detector is operating at our underground laboratory in Bern (70 m.w.e.). The detector relies on measuring the magnetic flux variation produced by weakly int…
Search for an annual modulation of dark-matter signals with a germanium spectrometer at the Sierra Grande Laboratory
D. Abriola, F. T. Avignone, R. L. Brodzinski +17
Data collected during three years with a germanium spectrometer at the Sierra Grande underground laboratory have been analyzed for distinctive features of annual modulation of the…
Annual modulation sensitivity in cold dark matter searches
F. Hasenbalg
The sensitivity of experiments looking for annual modulated signals is discussed and analyzed. The choice of energy intervals for rate integration and enhancing the signal-to-noise…
A Decommissioned LHC Model Magnet as an Axion Telescope
K. Zioutas, C. E. Aalseth, D. Abriola +23
The 8.4 Tesla, 10 m long transverse magnetic field of a twin aperture LHC bending magnet can be utilized as a macroscopic coherent solar axion-to-photon converter. Numerical calcul…
Experimental Search for Solar Axions
A. O. Gattone, D. Abriola, F. T. Avignone +16
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 i…
Experimental Search for Solar Axions via Coherent Primakoff Conversion in a Germanium Spectrometer
F. T. Avignone, D. Abriola, R. L. Brodzinski +16
Results are reported of an experimental search for the unique, rapidly varying temporal pattern of solar axions coherently converting into photons via the Primakoff effect in a sin…
