Abstract

The Workshop on results of the Project Kosmomikrofizyka-2 (Astroparticle Physics) of the National Academy of Sciences (NAS) of Ukraine "Astrophysical and cosmological problems of invisible mass and dark energy in the Universe" was held on November 21-22, 2012 in the Institute for Nuclear Research, Kyiv, Ukraine (http://lpd.kinr.kiev.ua/kmf12). This Project was carried out during three years (2010-2012) by scientists from various universities and institutes of the National Academy of Sciences of Ukraine; it was a logical continuation of the previous scientific program of the NAS of Ukraine "Researches of structure and composition of the Universe, hidden mass and dark energy (Kosmomikrofizyka)" in 2007-2009. These programs were devoted to theoretical and experimental investigations in astronomy, astrophysics, cosmology, physics of atomic nuclei and particle physics, which are related with the problems of dark matter and dark energy in the Universe., Comment: Proceedings of the Workshop on results of the Project Kosmomikrofizyka-2 (Astroparticle Physics) of the National Academy of Sciences of Ukraine, November 21-22, 2012, Institute for Nuclear Research, Kyiv, Ukraine. 94 pages, 29 figures, 5 tables (in English, Ukrainian, Russian)

Abstract

Cadmium tungstate crystal scintillators enriched in 106Cd and 116Cd were developed. The produced scintillators exhibit good optical and scintillation properties, and a low level of radioactive contamination. Experiments to search for double beta decay of 106Cd and 116Cd are in progress at the Gran Sasso National Laboratories of the INFN (Italy). Prospects to further improve the radiopurity of the detectors by recrystallization are discussed., Comment: 9 pages, 1 figure (4 eps-figs), 1 table.

Abstract

Energy resolution, light yield, non-proportionality in the scintillation response, alpha/beta ratio, pulse shape for gamma rays and alpha particles were studied with CdWO4 crystal scintillators. Some indication for a difference in the emission spectra for gamma rays and alpha particles was observed. No dependence of CdWO4 pulse shape on emission spectrum wavelengths under laser, alpha particles and gamma ray excitation was observed. Dependence of scintillation pulse shape for gamma quanta and alpha particles and pulse-shape discrimination ability on temperature was measured in the range of 0-24 degrees., Comment: 22 pages, 14 figures, submitted to NIMA

Abstract

PbWO4 crystal scintillators are discussed as an active shield and light-guides in 116Cd double beta decay experiment with CdWO4 scintillators. Scintillation properties and radioactive contamination of PbWO4 scintillators were investigated. Energy resolution of CdWO4 detector, coupled to PbWO4 crystal as a light-guide, was tested. Efficiency of PbWO4-based active shield to suppress background from the internal contamination of PbWO4 crystals was calculated. Using of lead tungstate crystal scintillators as high efficiency 4-pi active shield could allow to build sensitive double beta experiment with 116CdWO4 crystal scintillators., Comment: 12 pages, 5 figs

Abstract

The indication for the alpha decay of 180-W with a half-life T1/2=1.1+0.8-0.4(stat)+-0.3(syst)x10^18 yr has been observed for the first time with the help of the super-low background 116-CdWO_4 crystal scintillators. In conservative approach the lower limit on half-life of 180-W has been established as T1/2>0.7x10^18 yr at 90% C.L. Besides, new T1/2 bounds were set for alpha decay of 182-W, 183-W, 184-W and 186-W at the level of 10^20 yr., Comment: 16 pages, 8 figures, accepted in Phys. Rev. C

Abstract

A new phase of 116Cd double beta decay experiment is in progress in the Solotvina Underground Laboratory. Four enriched 116CdWO4 scintillators with total mass 339 g are used in a set up, whose active shield is made of 15 natural CdWO4 crystals (20.6 kg). The background rate in the energy interval 2.5-3.2 MeV is 0.03 counts/y*kg*keV. The half-life for 2-neutrino 2-beta decay of 116Cd is measured as T{1/2}(2-neutrino) = [2.6+-0.1(stat)-0.4+0.7}(syst)]*10**19 y. The T{1/2} limits for neutrinoless 2-beta decay of 116Cd are set as T{1/2} >= 0.7(2.5)*10**23 y at 90%(68%) C.L. for transition to ground state of 116Sn, while for decays to the first 2+ and second 0+ excited levels of 116Sn as T{1/2}>=1.3(4.8)*10**22 y and >=0.7(2.4)*10**22 y with 90%(68%) C.L., respectively. For 0-neutrino 2-beta decay with emission of one or two Majorons, the limits are T{1/2}(0-neutrino M1) >=3.7(5.8)*10**21 y and T{1/2}(0-neutrino M2)>=5.9(9.4)*10**20 y at 90%(68%) C.L. Restrictions on the value of the neutrino mass, right-handed admixtures in the weak interaction, and the neutrino-Majoron coupling constant are derived as: m(neutrino)<=2.6(1.4) eV, eta <=3.9*10**-8, lambda <=3.4*10**-6, and g{M}<= 12(9.5)*10**-5 at 90%(68%) C.L., respectively., Comment: 28 pages, 9 figures (LaTeX).

Abstract

voir fichier complet des proceedings; International audience; EURECA (European Underground Rare Event Calorimeter Array) will be an astro-particle physics facility aiming to directly detect galactic dark matter. TheLaboratoire Souterrain de Modane has been selected as host laboratory. TheEURECA collaboration concentrates effort on cryogenic detector research inEurope into a single facility by bringing together colleagues from CRESST,EDELWEISS, ROSEBUD and additional new member institutes. EURECA will use atarget mass of up to one ton for exploring WIMP-nucleon scalar scattering crosssections in the region of 10 −9 – 10 −10 picobarn. A major advantage of EURECAis the planned use of more than just one target material (multi targetexperiment for WIMP identification).

Abstract

An experiment to search for 2b processes in 106Cd with the help of 106CdWO4 crystal scintillator (mass of 215 g), enriched in 106Cd up to 66%, is in progress at the Gran Sasso National Laboratories of the INFN (Italy). After 1320 h of data taking, limits on double beta processes in 106Cd have been established on the level of 1019-1020 yr, in particular (all the results at 90% C.L.): T1/2(0ν2[variant_greek_epsilon])>3.6×1020 yr, T1/2(2ν[variant_greek_epsilon]β+)>7.2×1019 yr, and T1/2(2ν2β+)>2.5×1020 yr. Resonant 0ν2[variant_greek_epsilon] processes have been restricted as T1/2(0ν2K)>1.4×1020 yr and T1/2(0νLK)>3.2×1020 yr. A possible resonant enhancement of the 0ν2[variant_greek_epsilon] processes is estimated in the framework of the QRPA approach. [ABSTRACT FROM AUTHOR]

Abstract

Radioactive contaminations of CaWO4, ZnWO4, CdWO4, and Gd2SiO5:Ce crystal scintillators were measured in the Solotvina Underground Laboratory. The Monte Carlo simulation of contributing radioactive sources, the time-amplitude and pulse-shape analyses of the experimental data were applied. CaWO4 and GSO scintillators are considerably polluted by uranium and thorium, while the total α activity in ZnWO4 and CdWO4 scintillators does not exceed the level of a few mBq/kg. Particular radioactivity was observed in CaWO4 (α active 180W), CdWO4 (β active 113Cd, 2v2β decay of 116Cd, 180W), and GSO (α active 152Gd) detectors. The radioactive contamination of the studied scintillation crystals is compared with that of commonly used detectors. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]

Abstract

A new step of the [sup 116]Cd 2β-decay experiment is in progress at the Solotvina Underground Laboratory. The upgraded setup consists of four enriched [sup 116]CdWO[sub 4] crystal scintillators of total mass 339 g. As an active shield, 15 CdWO[sub 4] crystals (20.6 kg) are used. The background rate (in the energy interval 2.7-2.9 MeV) is 0.06 count/(yr kg keV), one order of magnitude lower than in the previous apparatus. Combined with results of preceding measurements, the half-life limit for the neutrinoless 2β decay of [sup 116]Cd to the ground state of [sup 116]Sn is determined as T[sub ½](0v) ≥ 5.1 x 10[sup 22] yr with 90% C.L. The limits on T[sub ½] for transitions to the excited 2[sup +, sub 1] and 0[sup +, sub 1] levels of [sup 116]Sn are 8.6 x 10[sup 21] and 4.1 x 10[sup 21] yr, respectively (at a 90% C.L.). For 0v2β decay accompanied by the emission of one and two Majorons, the constraints on the half-life are T[sub ½](0vM1) ≥ 1.4 x 10[sup 21] yr and T[sub ½] (0vM2) ≥ 4.1 x 10[sup 20] yr (at a 90% C.L.). The corresponding constraints on the neutrino mass and the neutrino-Majoron coupling constant are 〈m[sub v]〉 ≤ 3.1 eV and 〈g[sub M]〉 ≤ 1.9 x 10[sup -4], respectively. [ABSTRACT FROM AUTHOR]

Abstract

A low background scintillation detector with a CdWO4crystal of 1.046 kg was used to search forβ+β+andβ+/EC processes in106Cd. For the neutrinoless mode the limits T1/2(0νβ+β+)≥2.2·1019y and T1/2(0νβ+/EC)≥5.5·1019y were obtained with 90% C.L. For the possible two neutrino decay limits of T1/2(2νβ+β+)≥9.2·1017y and T1/2(2νβ+/EC)≥2.6·1017y have been determined with 99% C.L.
