“…The current statistical significance of the DAMA/LIBRA modulation result reaches the 12σ level. However, it has neither been reproduced by any other experiment, nor ruled out in a model independent way [5,6,7,8,9,10]. Compatibility among the different experimental results in most conventional WIMP-DM scenarios is actually disfavored [11,12].…”

ANAIS (Annual modulation with NaI Scintillators) is a dark matter direct detection experiment located at the Canfranc Underground Laboratory (LSC), in Spain. The goal is to confirm or refute in a model independent way the DAMA/LIBRA positive result: an annual modulation in the low-energy detection rate compatible with the expected signal induced by dark matter particles in the galactic halo. This signal, observed for about 20 years, is in strong tension with the negative results of other very sensitive experiments, but a direct comparison using the same target material, NaI(Tl), was still lacking. ANAIS-112, consisting of 112.5 kg of NaI(Tl) scintillators, is taking data at the LSC since August 2017. Here we present the preliminary annual modulation analysis corresponding to two years of data (exposure of 220.69 kg×y) and the ANAIS-112 projected sensitivity for the scheduled 5 y of operation.

“…First probed by 10 kg-scale cryogenic detector experiments [2,3,4,5,6,7] the 5-100 GeV WIMP mass range region is now extensively explored by ton-scale liquid noble gas detectors such as LUX [9], PandaX [10] and XENON [11] with no detection yet. This has raised an increasing interest in low-mass (< 5 GeV) WIMP searches [7,8,12,13,14,15] and motivated novel techniques to lower thresholds including single electron-hole sensitivity [16,17], however at the price of no more or very poor background discrimination.…”

Low-Noise HEMTs for Coherent Elastic Neutrino Scattering and Low-Mass Dark Matter Cryogenic Semiconductor Detectors

We present the noise performance of High Electron Mobility Transistors (HEMT) developed by CNRS/C2N laboratory. Various HEMT's gate geometries with 2 pF to 230 pF input capacitance have been studied at 4 K. A model for both voltage and current noises has been developed with frequency dependence up to 1 MHz. These HEMTs exhibit low dissipation, excellent noise performance and can advantageously replace traditional Si-JFETs for the readout of high impedance thermal sensor and semiconductor ionization cryogenic detectors. Our model predicts that cryogenic germanium detectors of 30 g with 10 eV heat and 20 eV ee baseline resolution are feasible if read out by HEMT-based amplifiers. Such resolution allows for high discrimination between nuclear and electron recoils at low threshold. This capability is of major interest for Coherent Elastic Neutrino Scattering and low-mass dark matter experiments such as Ricochet and EDELWEISS.

“…The full mass range SuperCDMS experiment [105] detected a single candidate event after an exposure of 1690 [kg d] consistent with backgrounds. This measurement has set new limits for DM-germanium interactions in the mass range 13 -127 GeV/c 2 [105].…”

The measurement of an annual modulation in the event rate of direct dark matter detection experiments is a powerful tool for dark matter discovery. Indeed, several experiments have already claimed such a discovery in the past decade. While most of them have later revoked their conclusions, and others have found potentially contradictory results, one still stands today. This paper explains the potential as well as the challenges of annual modulation measurements, and gives an overview on past, present and future direct detection experiments.
