Investigating Optical Coupling Material Candidates in NaI(Tl) Detectors for the SABRE-North Dark Matter Experiment
Chemseddine Ananna, Gabriella Cataldi, Davide D'Angelo +21
Direct dark matter detection with NaI(Tl) scintillators requires ultra-low-background materials. Silicone optical pads can couple NaI(Tl) crystals to photomultiplier tubes (PMTs) i…
RadioAxion results on the search for axion dark matter under Gran Sasso
Carlo Broggini, Giuseppe Di Carlo, Luca Di Luzio +2
We report first results from RadioAxion, an underground experiment searching for axion dark matter through periodic modulations of radioisotope decays. We monitor the decay of…
Application of zone refining to the development of NaI(Tl) detectors for SABRE North
C. Ananna, F. B. Armani, G. Cataldi +23
The SABRE North experiment is developing ultra-high radiopurity NaI(Tl) detectors to investigate dark matter. To achieve this, SABRE North utilizes the technique called zone refini…
Alpha radioactivity deep-underground as a probe of axion dark matter
Carlo Broggini, Giuseppe Di Carlo, Luca Di Luzio +1
We propose to investigate the time modulation of radioisotope decays deep underground as a method to explore axion dark matter. In this work, we focus on the -decay of heavy iso…
The ASTAROTH project
Davide D'Angelo, Andrea Zani, Franco Alessandria +14
The most discussed topic in direct search for dark matter is arguably the verification of the DAMA claim. In fact, the observed annual modulation of the signal rate in an array of…
Measurement and control of a superconducting quantum processor with a fully-integrated radio-frequency system on a chip
Mats O. Tholén, Riccardo Borgani, Giuseppe Ruggero Di Carlo +8
We describe a digital microwave platform called Presto, designed for measurement and control of multiple quantum bits (qubits) and based on the third-generation radio-frequency sys…
Performance of the SABRE detector module in a purely passive shielding
F. Calaprice, J. B. Benziger, S. Copello +19
We present here a characterization of the low background NaI(Tl) crystal NaI-33 based on a period of almost one year of data taking (891 kgxdays exposure) in a detector configurati…
Precise measurement of the 222Rn half-life: a probe to monitor the stability of radioactivity
E. Bellotti, C. Broggini, G. Di Carlo +2
We give the results of a study on the 222Rn decay we performed in the Gran Sasso Laboratory (LNGS) by detecting the gamma rays from the radon progeny. The motivation was to monitor…
Search for time modulations in the decay rate of 40K and 232Th
E. Bellotti, C. Broggini, G. Di Carlo +3
Time modulations at per mil level have been reported to take place in the decay constant of about 15 nuclei with period of one year (most cases) but also of about one month or one…
Search for correlations between solar flares and decay rate of radioactive nuclei
E. Bellotti, C. Broggini, G. Di Carlo +2
The deacay rate of three different radioactive sources 40K, 137Cs and natTh has been measured with NaI and Ge detectors. Data have been analyzed to search for possible variations i…
Search for the time dependence of the 137Cs decay constant
E. Bellotti, C. Broggini, G. Di Carlo +2
Starting from June 2011, the activity of a 137Cs source has been measured by means of a HPGe detector installed deep underground in the Gran Sasso Laboratory. In total about 5100 e…
U and Th content in the Central Apennines continental crust: a contribution to the determination of the geo-neutrinos flux at LNGS
M. Coltorti, R. Boraso, F. Mantovani +8
The regional contribution to the geo-neutrino signal at Gran Sasso National Laboratory (LNGS) was determined based on a detailed geological, geochemical and geophysical study of th…
