Neutron scattering facility for the calibration of the response to nuclear recoils

AIP conference proceedings (2002)

Johanna K. Jochum B. Chambon D. Drain F. von Feilitzsch J. Gascon

A possibility to search for elementary particles as dark matter candidates is to detect elastic scattering with cryogenic detectors. For the interpretation of the data one has to determine the detector response to nuclear recoils, the so-called quenching factors. They can differ for the heat-, for the scintillation- and for the ionization-signal and can be measured by scattering of neutrons. The CRESST- and the EDELWEISS-collaborations have set up a neutron scattering facility for cryogenic detectors at the tandem-accelerator of the Munich 'Maier-Leibniz-Labor.' The scattering angle and the time-of-flight of the neutrons are measured by an array of liquid scintillator cells. The pulsed high energy (11 MeV) neutron beam is created by nuclear reaction of a 11B on a H2-gas target. The set-up and the results of first tests are presented.

The EDELWEISS Experiment: Status and Outlook

arXiv (Cornell University) (2001)

J. Gascon A. Bonnevaux P. Charvin B. Chambon L. Vagneron

The EDELWEISS Dark Matter search uses low-temperature Ge detectors with heat and ionisation read- out to identify nuclear recoils induced by elastic collisions with WIMPs from the galactic halo. Results from the operation of 70 g and 320 g Ge detectors in the low-background environment of the Modane Underground Laboratory (LSM) are presented.

Recherche de WIMPs par l'expérience EDELWEISS: caractérisation des détecteurs et analyse des données

O. Martineau

Les WIMPs (Weakly Interacting Massive Particles) pourraient etre une des composantes principales de la matiere noire, et ainsi representer une part predominante de la masse de l'Univers. Ils seraient presents a l'echelle galactique sous la forme d'un halo. Plusieurs experiences tentent de detecter directement les WIMPs du halo de notre Galaxie en cherchant a mettre en evidence leurs interactions dans un detecteur cible. Parmi celles-ci, l'experience EDELWEISS utilise la bolometrie, technique de detection a tres basses temperatures (environ 10 mK) des phonons produits par un depot d'energie dans un absorbeur. Les bolometres utilises par EDELWEISS associent a la detection des phonons celle des charges creees par le depot d'energie. Cette double detection permet de rejeter une grande partie du bruit de fond associe aux interactions electroniques. Nous presentons ici l'analyse des donnees enregistrees avec le premier bolometre de 320 grammes utilise par la collaboration EDELWEISS. Nous developpons en particulier une methode permettant de determiner sa masse efficace de detection. Cette methode est basee sur la modelisation des processus de collection de charge, des etalonnages du detecteur et avec des sources radioactives de 60Co et 252Cf et des simulations de ces calibrations avec le code GEANT. Nous caracterisons aussi la discrimination entre interactions electroniques et nucleaires par des etalonnages avec une source de neutrons, en evaluant l'influence des interactions multiples sur cette discrimination. Nous presentons enfin l'analyse des donnees de recherche des WIMPs et en deduisons une limite sur la section efficace de diffusion WIMP-nucleon.

The Giant Radio Array for Neutrino Detection

Proceedings of 36th International Cosmic Ray Conference — PoS(ICRC2019) (2019)

O. Martineau

The Giant Radio Array for Neutrino Detection (GRAND) is a proposal for a giant observatory of ultra-high energy cosmic particles (neutrinos, cosmic rays and gamma rays). It will be composed of twenty subarrays of 10 000 antennas each, to be deployed after 2030 at various locations around the world, totaling a detection area of 200 000 km². According to simulations, GRAND will reach unprecedented sensitivity to neutrinos of astrophysical origin with energies above 10^17 eV, sufficient to guarantee their detection. GRAND sub-degree angular resolution will also make it possible to hunt for point sources and possibly start neutrino astronomy. This, combined with the large instantaneous field of view expected from the location of the sub-arrays in different continents and hemispheres, will make GRAND a key instrument in the forth-coming era of multi-messenger transient astronomy, during which the century-long mystery of the nature and origin of the particles with highest energy in the Universe may be solved.

Direct and indirect detection of WIMPs

arXiv (Cornell University) (2001)

O. Martineau

We present here the principles of detection of Weakly Interacting Massive Particles, which could represent a large contribution to Dark Matter. A status of the experimental situation is given both for indirect and direct detection. In particular, the DAMA claim for a WIMP signal is confronted to the recent results of the CDMS and EDELWEISS experiments. We conclude by comparing direct and indirect search sensitivities.
