The 3Dpi scanner is a Total-Body, Time of Flight, Positron Emission Tomography (PET) imaging device with silicon photomultiplier (SiPM) and a xenon-doped Liquid Argon (LAr) scintillator with the aim of ultra-low-dose imaging for pediatric and pregnant patients. The scanner has an axial field-of-view of 200 cm and consists of nine double-sided concentric rings of SiPM panels. The xenon doping...
Project 8 is a next-generation experiment aiming to directly measure the neutrino mass using the tritium endpoint method with a targeted sensitivity of 40 meV. The development of new technology and methods are required to reach this unprecedented sensitivity. Having established a new measuring technique, Cyclotron Radiation Emission Spectroscopy (CRES), we are now focusing on the scaling of...
Next generation liquid nobel gas detectors for the search of weakly interacting massive particles (WIMPs), such as XLZD, aim to increase their sensitivity down to the neutrino fog. This ambitious goal can only be achieved by further reducing the detector backgrounds dominated by LXe intrinsic isotopes of 85Kr and 222Rn to a factor ten below the unshieldable solar and atmospheric neutrino...
The FCC-ee or Future Circular Collider for electrons and positrons is a key study in CERN’s long-term programme, aiming to advance precision physics through unprecedented energies and luminosities. Achieving these goals requires an ultra-high vacuum system maintaining pressures below $10^{-10}$ bar along a 90km ring. Two vacuum chambers (VCs) form a 180km long system, that must combine...
The Einstein Telescope (ET) will be a third generation gravitational wave detector consisting of a set of low frequency and a high frequency interferometers. In order to mitigate thermal noise, the mirrors for the low frequency interferometer are required to be cooled down to cryo temperatures. This leads to freezing of residual gas from the vacuum chamber onto the mirror surface. This will...
The Karlsruhe Tritium Neutrino (KATRIN) experiment was designed to measure the absolute neutrino mass scale based on a high-precision measurement of the tritium β-decay spectrum, close to its endpoint.
Its unprecedented tritium source luminosity and spectroscopic quality makes it a unique instrument to also search for physics beyond the Standard Model (BSM). Most notably, a keV-scale sterile...
Detectors for direct dark matter searches based on noble liquids require highly stable cryogenic systems capable of liquefying, purifying, and continuously recirculating the target medium. The Proto-0 setup, developed within the DarkSide experiment, is a compact dual-phase liquid argon TPC aimed at studying the spatial distribution of scintillation and ionization signals with large SiPM...
The ET cryogenic tower will operate at 10–20 K, featuring exceptionally low vacuum level and implementing ultra-low noise technologies. Beyond cryostat development, a number of elements and GW instrumentation remain to be adapted or validated. Here we present an existing cryostat located at Virgo site, known as the ‘1500W’ facility, recently refurbished and operated with cryocoolers...
