Experimental Search for Solar Axions via Coherent Primakoff Conversion in a Germanium Spectrometer
/ Avignone, F.T., III (South Carolina U.) ; Abriola, D. (CNEA, Buenos Aires) ; Brodzinski, R.L. (PNL, Richland) ; Collar, J.I. (CERN) ; Creswick, R.J. (South Carolina U.) ; DiGregorio, D.E.

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 single crystal germanium detector. This conversion is predicted when axions are incident at a Bragg angle with a crystalline plane. [...]

A Decommissioned LHC Model Magnet as an Axion Telescope
/ Zioutas, K. (Thessaloniki U.) ; Aalseth, C.E. (South Carolina U.) ; Abriola, D. (CNEA, Buenos Aires) ; Avignone, F.T., III (South Carolina U.) ; Brodzinski, R.L. (PNL, Richland) ; Collar, J.I. (CERN) ; Creswick, R. (South Carolina U.) ; Di Gregorio, D.E. (CNEA, Buenos Aires) ; Farach, H. (South Carolina U.) ; Gattone, A.O. (CNEA, Buenos Aires) et al.
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 calculations show that the integrated time of alignment with the Sun would be 33 days per year with the magnet on a tracking table capable of $\pm 5^o$ in the vertical direction and $\pm 40^o$ in the horizontal direction.

Cold dark matter identification : Diurnal modulation revisited
/ Hasenbalg, F. (South Carolina U.) ; Abriola, D. (CNEA, Buenos Aires) ; Avignone, F.T. (South Carolina U.) ; Collar, J.I. (CERN) ; Di Gregorio, D.E. (CNEA, Buenos Aires) ; Gattone, A.O. (CNEA, Buenos Aires) ; Huck, H. (CNEA, Buenos Aires) ; Tomasi, D. (CNEA, Buenos Aires) ; Urteaga, I. (CNEA, Buenos Aires)
We report on new estimates of the modulation expected in semiconductor detectors due to eclipsing of dark matter particles in the Earth. We re-evaluate the theoretical modulation significances and discuss the differences found with previous calculations. [...]

Theory for the Direct Detection of Solar Axions by Coherent Primakoff Conversion in Germanium Detectors
/ Creswick, R.J. (South Carolina U.) ; Avignone, F.T., III (South Carolina U.) ; Farach, H.A. (South Carolina U.) ; Collar, J.I. (CERN) ; Gattone, A.O. (CNEA, Buenos Aires) ; Nussinov, S. (Tel Aviv U.) ; Zioutas, K. (Thessaloniki U.)
It is assumed that axions exist and are created in the Sun by Primakoff conversion of photons in the Coulomb fields of nuclei. Detection rates are calculated in germanium detectors due to the coherent conversion of axions to photons in the lattice when the incident angle fulfills the Bragg condition for a given crystalline plane.

Use of electrodeposition for sample preparation and rejection rate prediction for assay of electroformed ultra high purity copper for $^{232}$Th and $^{238}$U prior to inductively coupled plasma mass spectrometry (ICP/MS)
/ Hoppe, E W (PNL, Richland) ; Aalseth, C E (PNL, Richland) ; Brodzinski, R (PNL, Richland) ; Day, A R (PNL, Richland) ; Farmer, O T (PNL, Richland) ; Hossbach, T W (PNL, Richland) ; McIntyre, J I (PNL, Richland) ; Miley, H S (PNL, Richland) ; Mintzer, E E (PNL, Richland) ; Seifert, A (PNL, Richland) et al.
The search for neutrinoless double beta decay in $^{76}$Ge has driven the need for ultra-low background Ge detectors shielded by electroformed copper of ultra-high radiopurity (<0.1 μBq/kg). Although electrodeposition processes are almost sophisticated enough to produce copper of this purity, to date there are no methods sensitive enough to assay it. [...]
