The Tunka observatory is located close to Lake Baikal in Siberia, Russia. Its main detector, Tunka-133, is an array of photomultipliers measuring the Cherenkov light emitted by cosmic-ray air showers. It is used to study cosmic rays up to energies of approximately 1 EeV, which is the energy range of the assumed transition from galactic to extra-galactic cosmic rays. The Tunka Radio Extension...

The Tokai Intermediate Tank for Unoscillated Spectrum (TITUS)
detector is a proposed addition to the Hyper-Kamiokande (Hyper-K)
experiment, located approximately 2 km from the J-PARC neutrino beam.
The design consists of a 2 kton Gd-doped water Cherenkov tank, partially
covered by a magnetised muon range detector. The target material and
location were chosen so that the neutrino...

The goal of the Stereo experiment is to answer the question of the existence of a sterile neutrino with a mass around 1 eV. The proposed measurement will take place at short distance from the research reactor of ILL in Grenoble. If a sterile neutrino exists then one should observe a distortion of the energy spectrum of the reactor electron antineutrinos induced by the mixing with the new...

To precisely determine BBN 6Li production, the cross section of the nuclear reaction $^2$H(ฮฑ,ฮณ)$^6$Li must be directly measured within the astrophysical energy range of 30-400 keV.
Since the cross section is of the order of nanobarn, the expected counting rate is very low indeed, therefore this measurement requires an ultra-low ฮณ-ray background in the experimental set-up.
We have realized...

The detection of gravitational waves is one of the most challenging prospects faced by experimental physicists. Suspension thermal noise is an important noise source at operating frequencies between approximately 10 and 30 Hz, and represents a limit to the sensitivity of the ground based interferometric gravitational wave detectors. Its effects can be reduced by minimizing the losses and...

One of the main backgrounds in the search for 129Xe nutrinoless double-beta decay (0$\nu\beta\beta$) is the signal from Compton scattering of photons with energy around the decay end point at 2.458 MeV.
One efficient method to exclude this background is by self-shielding, resulting in a waste of active volume.
Another proposed method is tagging the daughter barium nucleus, which relies on...

Gamma-ray astronomy allows us to explore the non-thermal emissions of
objects such as Active Galatic Nuclei (AGN), Gamma Ray Bursts (GRB) and pulsars. Current gamma-ray telescopes based on photon conversion to electron-positron pair use tungsten converters. They suffer of limited angular resolution at low energies, and their sensitivity drops below 1 GeV. A gaseous detector can achieve higher...
