A 10 kilo-tonne dual-phase liquid argon TPC is one of the detector options considered for Deep Underground Neutrino Experiment (DUNE). The technology relies on amplification ionisation charge in ultra-pure vapour and offers several advantages compared to traditional single-phase TPCs. 4.2 tonne prototype, largest its kind, with an active volume \three has been constructed operated at CERN. In this paper we describe detail experimental setup components as well report operation experience. We...
We use an underground counting lab with extremely low background to perform activity measurement for the C12+13C system energies down Ec.m.=2.323 MeV, at which 12C(13C,p)24Na cross section is found be 0.22(7) nb. The fusion derived a statistical model calibrated using experimental data. Our new result of first decisive evidence in carbon isotope systems rules out existence astrophysical S-factor maximum predicted by phenomenological hindrance model, while confirming rising trend towards...

Three highly sensitive analytical methods: epithermal neutron activation analysis (ENAA), radiometric assay and UV/Vis spectroscopy were used to investigate the elemental composition of both halite mineral fractions (sediments) salt collected from Slanic-Prahova mine, near location Low Background Radiation Laboratory. For with all three methods within experimental uncertainties, it was not possible observe presence any natural radioactive elements. fraction ENAA showed 40K, 232Th 238U in...
The feasibility of a next generation neutrino observatory in Europe is being considered within the LAGUNA design study. To accommodate giant detectors and shield them from cosmic rays, new very large underground infrastructure required. Seven potential candidate sites different parts at several distances CERN are studied: Boulby (UK), Canfranc (Spain), Fr\'ejus (France/Italy), Pyh\"asalmi (Finland), Polkowice-Sieroszowice (Poland), Slanic (Romania) Umbria (Italy). study aims comprehensive...
Measurements of I-131 (T1/2 = 8.04 days) have been performed in IFIN-HH's underground laboratory situated Unirea salt mine from Slanic-Prahova, Romania. The rain water samples were collected March 27th Brasov and 27th, 29th April 2nd Slanic. Also sheep milk was Slanic area subsequently measured. measured the ultra-low radiation background, using a high resolution gamma-ray spectrometer equipped with GeHP detector having FWHM 1.80 keV at 1332.48 second Co-60 gamma-ray, relative efficiency...
Nowadays, nuclear astrophysics has to give high precision values for which are part of stellar evolution models. The stable beam accelerators play an important role in the process measuring very low energy cross sections. event reaction rate may be separated from background only if it exceeds detection limit. One go deep underground lower background. In this paper, we make a proposal realize lab dedicated salt mine Romania.
Heavy-ion fusion reactions between light nuclei such as carbon and oxygen isotopes have been studied because of their significance for a wide variety stellar burning scenarios. One important reaction is 12C+12C, but it difficult to measure in the Gamow window very low cross sections several resonances occurring. Hints can be obtained from study 13C+12C reaction. We measured this process by an activation method energies down Ecm=2.5 MeV using 13C beams Bucharest 3 MV tandetron gamma-ray...
Precise measurements of the muon flux are important for different practical applications, both in environmental studies and estimation water equivalent depths underground sites. A mobile detector cosmic has been set up at IFIN-HH, Romania. The device is used to measure on locations surface underground. Its first configuration, not present, composed two 1 m 2 scintillator plates, each viewed by wave length shifters read out Photomultiplier Tubes (PMTs). more recent consists detection layers,...
In the recent work at Notre Dame, correlations between three carbon isotope fusion systems have been studied and it is found that cross sections of 12C+13Cand 13C+13C provide an upper limit on section astrophysically important 12C+12C reaction.The aim this to continue such research by measuring 12C+13C reaction lower energies. experiment, off-line activity measurement was performed in ultra-low background laboratory for has determined energy range Ec.m. =2.5–6.8 MeV. Comparison several models...
Aerosol samples collected on filter media were analyzed using HPGe detectors employing varying background-reduction techniques in order to experimentally evaluate the opportunity apply ultra-low background measurement methods collected, for instance, by Comprehensive Test Ban Treaty International Monitoring System (IMS). In this way, realistic estimates of impact low-background methodology sensitivity obtained systems such as IMS assessed. The current detectability requirement stations is 30...
