Ultra Low Temperature Dark Matter Detector with 30% of Non-paired Neutrons. (15'+5')
 
A direct Dark Matter detector of a new type, developed in the framework of
the “ULTIMA” project, is ready to be installed at the Canfranc underground
laboratory. It is based on properties of superfluid 3He at the limit of
extremely low temperatures of about 0.1 mK. At these temperatures all 3He
atoms are condensed in a coherent superfluid state with a heat capacity of
about 10 keV per gram.  On the prototype of this detector, we have achieved
the sensitivity of 1keV events.  We have developed new techniques of
electron/nuclear recoil discrimination on the basis of pulse shape analysis. The 
main
advantage of our detector is the 30% concentration of non-paired
neutrons in 3He nuclei, which makes it a premier material for testing the
axially interacting Dark Matter. The quantum coherence of superfluid 3He can 
be also
interesting in order to probe some exotic types of Dark Matter. The 
experimentally
measured surface limits for specific nuclear-interacting form of  Dark Matter will 
be
presented.
