DAMIC EoI-21-2018

Dark Matter in CCDs (DAMIC) has pioneered the detection of nuclear and electronic recoils induced by Dark Matter (DM) particles in charge-coupled devices (CCDs). Scientific CCDs are commonly used in the focal plane of astronomical telescopes for the digital imaging of faint astrophysical objects. Our non-standard use of CCDs was demonstrated at SNOLAB (Sudbury, Canada) where a 40-g prototype detector is currently operating. DAMIC-M is a 1 Kg detector to be installed at Laboratoire Souterrain de Modane (LSM) in France which profits from this experience and, at the same time, will greatly improve in sensitivity by further innovating the detector technology. CCDs show unique properties: a) unprecedented charge resolution, b) low leakage current, c) spatial resolution and 3D reconstruction, d) background identification and rejection.

LU EoI-20-2018

Low-level γ spectroscopy with High Purity Germanium (HPGe) detectors has become an essential tool for material screening in rare event physics experiments, which demand the lowest radioactivity levels. Typical examples are searches for solar neutrinos, neutrinoless double beta decay and dark matter. Compared to other methods, such as mass spectrometry or neutron activation, spectroscopy provides a comprehensive method in a non-destructive way without complex sample treatment. The primordial radioisotopes 232Th, 238U and 40K represent the main sources of contamination in common materials. Concerning the two former isotopes, only HPGE spectroscopy can verify secular equilibrium as it is capable of measuring the concentration of their progenies near the end of their respective decay chains – in particular 208Tl and 214Bi.

CUNA EoI-12-2009

In 2009 an Expression of Interest entitled “A Nuclear Astrophysics facility for LSC: The sources of neutrons in the stars and other reactions of astrophysical interest” (CUNA) was submitted to the LSC by Spanish groups and international partners. It was followed by a Letter of Intent, which was submitted in 2012. The idea was to install a high-current multi-MV accelerator at the LSC to measure reactions of importance in nuclear astrophysics.
