Welcome to the homepage of the Low Temperature Detectors for Neutrino Physics development group. Our Cryogenic Laboratory is hosted by the Physics Department of Milano-Bicocca University and it is run in collaboration with the Istituto Nazionale di Fisica Nucleare (Sezione di Milano-Bicocca).

We are currently developing Low Temperature Detectors mostly for neutrino physics (Direct neutrino mass measurements, Neutrinoless double beta decay searches, ...). Our goal is to conceive, develop, and carry out experiments to answer some outstanding questions about neutrinos, but the cutting edge techniques  we develop may also have an impact in many frontier fields like astrophysics, material analysis, nuclear safety and diagnostic, archaeometry, and quantum technologies.

Our research is highly interdisciplinary and combines expertises in condensed matter, atomic, nuclear, and sub-nuclear physics, thin film technology, device micro-fabrication, low temperature techniques, superconducting electronics, microwave electronics, digital signal processing and large cryogenic systems. 

A new low temperature laboratory is being set up at University of Milano-Bicocca in building U19.

The laboratory will host 5 cryogen-free dilution refrigerators dedicated to neutrino physics (HOLMES experiment) and astrophysics (RES-NOVA experiment), to high frequency gravitational waves detection (BAUSCIA project), and to quantum science and technology research.

The laboratory is made possible by the financial contributions of National Science and Technology Institute (NQSTI) initiative of PNRR, of MUR through the Centro Bicocca di Cosmologia Quantitativa (Dipartimenti di eccellenza 2023-2027),  EU (through ERC AdG 340321, ERC CoG 101087295 and MSCA-IF 101027746), and INFN (through CSN2 and CSN5)

University of Milano-Bicocca is affilliated to the National Centre for HPC Big Data and Quantum Computing (ICSC) and to National Science and Technology Institute (NQSTI) initiative of the PNRR.

The Cryogenics Laboratory and BiQuTe will play a crucial role supporting the activities for the development of superconducting quantum devices in the Quantum Computing Spoke of ICSC and in the Integration and Complete Quantum Systems spokes of NQSTI. University of Milano-Bicocca is leader of the spoke Integration of NQSTI which is devoted to the integration of quantum systems.

In particular the activities are highly synergic with the Dartwars and qub-IT projects and they will be carried out in collaboration with groups from INFN, FBK, CNR and University of Naples.

ICSC and NQSTI are also funding PhD positions at University of Milano-Bicocca linked to BiQuTe activity in Quantum Technologies. For more information please contact Angelo Nucciotti.

The Cryogenic Laboratory is hosted by the Physics Department of the Milano-Bicocca University. The Laboratory is one of the largest and most advanced cryogenic facility dedicated to radiation detector research, particle physics experiments, and quantum technologies worldwide.

The Laboratory is located at the third level underground: this location provides an environment protected from vibrations, electromagnetic interference and allows also for a slight reduction of cosmic rays. It hosts four He³/He⁴ dilution refrigerators which allow the cooling of relatively large (from 3500 to 30000 cm³ ) experimental set-ups to temperatures as low as 0.01 K. The newest of the four refrigerators is cryogen-free. 

The Laboratory is fully equipped for low temperature radiation detector testing as well as with vacuum and low temperature instrumentation, calibration sources, electronic instrumentation (oscilloscopes, function generators, power supplies, multimeters, etc.), data acquisition systems, instrument control systems and computing and data storage systems.  The Cryogenic Laboratory maintenance and activity is supported by INFN. 

The activity in the Cryogenic Laboratory is connected also to other facilities in the Department:

• the Detector Assembly Laboratory featuring a ISO 6 (class 1000) clean area equipped with a 6 axis micro-positioning tool, microscopes, a 2 micrograms precision balance and  bonding machines (both ball and wedge)
• the Low Radioactivity Laboratory, equipped with four shielded low activity high efficiency High Purity Germanium Gamma Spectrometers and two planar Germanium X-ray spectrometers.
• the ICP-MS Laboratory, with a class 1000 fully equipped Clean Room hosting two ICP-MS spectrometers (one Quadrupole ICP-MS and one Double Focusing Magnetic Sector ICP-MS allow the determination of trace elements with concentrations of one part in 10¹² and 10¹⁵, respectively)
• the Electronic Laboratory
• the Machine Workshop
