Scientific ProgrammePhysics
  • - Approved experiments on proposal of the
    International Scientific Committee.
  • 3 years running. Milestones defined. Two referees
    appointed to each exp
  • EXP-01-2008 (ANAIS) Dark Matter (NaI, Annual
    modulation)
  • Direct check of DAMA/LIBRA result
  • EXP-02-2008 (ROSEBUD) Dark Matter (Scintillating
    bolometers)
  • Integrated in the European EURECA project
  • EXP-03-2008 (BiPo) 0??? decay (extra-low surface
    background meas.)
  • Ancillary to Super-NEMO
  • EXP-04-2008 (ULTIMA) Super-fluid 3He physics

    TPC)
  • Majorana vs Dirac neutrinos
  • CUP Consolider approved
  • EoI-02-2005 (ArDM) EoI on Dark Matter (Liquid
    Argon TPC)

Dark Matter
  • 95 of the Universe mass-energy is dark
  • Status of the art. Calorimetric approach target
    of dark particles detector
  • sensitive detector mass M several kg
  • best background bO(103 kg1keV1 d1)
  • To explore theoretical range need MO(1t) and bO
    (105 kg1keV1 d1)
  • This levels may be reached in the next few years
    by noble liquids
  • 10-100 kg Xe and Ar modules operational / under
    construction at LNGS
  • Xe and Ar complementary, both in physics and
    technique. Both should be done
  • Do not forget other techniques. Hunting for dark
    matter is extremely difficult
  • Strong competition world wide
  • DAMA positive evidence can be confirmed/rejected
    only by an annual modulation sensitive experiment
    with Iodine nuclei

10
EXP-01-2008 ANAIS
Search for the annual modulation Confirm/refute
DAMA evidence
Work on a series of prototype performed in the
old LSC using 14?10.7 kg NaI crystals stored
underground since 1988
  • Contribution to background of internal
    contamination at 2-6 keV
  • UTh lt 1/ (keV kg d) OK
  • 40K several/(keV kg d) too large
  • New crystals required
  • Funded about 100 kg by MCINN Program
  • Additional NaI procurementwith LSC funding under
    examination

11
EXP-02-2008 ROSEBUD
Develop cryogenic temperatures bolometers with
heat and scintillation light readout, focussing
on prototypes for EURECA (next-generation
European project for DM search with bolometers)
12
EoI-02-2005 ArDM
Ar two-phase TPC Tests on 1 t prototype going on
at CERN Preliminary LSC risk analysis stage
13
Neutrino-less Double beta decay
  • Unlike the other particles neutrinos may be
    matter and antimatter at the same time
  • Two approaches calorimetric and tracking
  • Status of the art of calorimetric approach (two
    experiments _at_ LNGS)
  • Exposure O (100 kg yr)
  • Background bO(102 kg1keV1 y1)
  • Complementary tracking approach necessary, on
    different isotopes, with similar sensitive masses
  • Due to limited overburden of LSC ? tracking
    approach (calorimetry already covered by CUORE
    and GERDA)
  • SuperNEMO _at_ 100 kg does not fit in LSC
  • Extrapolates NEMO3 technology. However, much RD
    needed
  • First steps BiPo and its prototypes
  • Liquid Xe TPC. EXO 200 kg in the US
  • Gas TPC with novel RD techniques
  • Much RD needed. NEXT

Case of 136Xe assuming T1/2(????)?1021 (measured

High pressure TPC Strong RD effort needed

16
EXP-05-2008 NEXT
  • High pressure gas TPC with enriched 136Xe
    Complementary to EXO
  • Status. Initial RD phases. CUP Consolider
    (mainly NEXT) approved (5 M)
  • Avoid charged background from surfaces by
    eliminating surfaces, based on 100 active,
    completely closed virtual fiducial surface
  • Obtain fine topological information (unlike EXO)
  • Tag signal by topology 2 balls at the end of the
    spaghetti
  • Expected reduction of (dominant) gamma background
    gt 100
  • FWHM resolution O(1) appears feasible with
    latest TPC R/O techniques
  • Montecarlo evaluation of the tolerable
    radioactive contaminants in materials screening
    starting now

17
EXP-04-2008 ULTIMA100 µK superfluid 3He detector
Density of quasi-particles determined directly by
measuring the damping of micro vibrating wire
Originally proposed for dark matter direct search
via spin-dependent coupling Detector sensitive
mass very small (grams) The super-fluid phase of
the 3He-4He mixture might be observable at these
temperatures Signal is confused by cosmic muons
interference on the surface

Possible location of the experiments
Laboratory space is almost full

  • What makes life successful deep under the
    surface?
  • What can life underground teach us about how life
    evolved?
  • Status of art. Studies made by Henderson DUSEL
    project in US
  • 2 new Phyla discovered at Henderson
  • Cross-disciplinary work between biologists and
    geologists
