“…Natural Sm was deposited on the surface of the reflecting foil facing the Li 2 MoO 4 crystal on the opposite side of the LD, 147 Sm was used as α source for illuminating the crystal. Finally an Am-Be neutron source was placed close to the detector for studying the neutron capture reaction on 6 Li.…”

“…By means of scintillating properties these types of interactions can be easily identified and discarded. High-scale projects of 100 Mo 0νDBD search with sensitivity T 1/2 10 26 yr are known with two Mo-containing scintillating bolometers: CaMoO 4 [6] and ZnMoO 4 [7,9]. Appearance of new highly radiopure scintillator in this field can be very interesting.…”

“…Lithium molybdate (Li 2 MoO 4 ) crystal scintillators can have important applications in applied physics (detection of neutron fluxes through n captures by 6 Li) as well as in fundamental physics in searches for neutrinoless double-beta decay (DBD), dark matter (DM) and solar 7 Li axions. Double-beta decay is a process of rare nuclear transformation (A, Z) → (A, Z ± 2) with simultaneous emission of two electrons or positrons.…”

“…by simultaneous measurement of the heat and light channels [5]. Recently, several compounds containing Mo have been studied [6] [7] [8], all of them have shown a great ability to identify α interactions from β /γ ones. This feature is extremely important because, as demonstrated by the CUORICINO collaboration [20], in DBD bolometric experiments, one of the primary background sources are degraded α particles interacting with the detector.…”

We present the performance of a 33 g Li 2 MoO 4 crystal working as a scintillating bolometer. The crystal was tested for more than 400 h in a dilution refrigerator installed in the underground laboratory of Laboratori Nazionali del Gran Sasso (Italy). This compound shows promising features in the frame of neutron detection, dark matter search (solar axions) and neutrinoless double-beta decay physics. Low temperature scintillating properties were investigated by means of different α, β /γ and neutron sources, and for the first time the Light Yield for different types of interacting particle is estimated. The detector shows great ability of tagging fast neutron interactions and high intrinsic radiopurity levels (< 90 µBq/kg for 238 U and < 110 µBq/kg for 232 Th).

“…The arguments to develop CaMoO 4 are as follows: 100 Mo is one of the most promising candidate to search for neutrinoless double beta decay (a key process in the modern physics) [34]; CaMoO 4 contains valuable part of Mo (48%); CaMoO 4 does not contain radioactive elements; CaMoO 4 is a reasonably ecient scintillator even at room temperature [35]; CaMoO 4 is a promising material for low temperature scintillating bolometers (with high energy resolution and particle discrimination ability) [36,37].…”

Calcium molybdate is considered as a very promising scintillator material for experimental studies of rare processes. This paper reports on the production and characterization of a 40 Ca 100MoO 4 scintillator. Using the Czochralski technique, a crystal of high optical quality with total mass 0.55 kg, 42 mm diameter (minimum) and 53 mm 1ength of the cylindrical section was produced from isotopically enriched raw materials, containing 96.1% of 100 Mo and 99.964% of 40 Ca. To satisfy the requirement of low intrinsic radioactivity the purity of the materials was monitored at different stages of the production process and it is shown that the concentration of 238 U and 232 Th in the final crystal does not exceed 0.05 ppb. The scintillation properties of 40 Ca 100 MoO 4 were measured over the 8 -300 K temperature range and it is found that the light yield of the 40 Ca 100MoO 4 crystal is very similar to that of the CaMoO 4 reference scintillator.
