Scientific ProgrammePhysics

• - Approved experiments on proposal of the
  International Scientific Committee.

  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)

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

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

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

Dark Life

• Microbiology
• How deeply in the earth does life extend?
• 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
• Do bacteria enter into the genesis of minerals
  and rocks?
