Workshop on DEtectores for Underground Searches of new physics - DEUS (

Session chair: Prokopovich, Dale, A. (Australian Nuclear Science and Technology Organisation, Australia)
 
Shortcut: NSS-WS2 I
Date: Sunday, 11 November, 2018, 9:00 AM
Room: Meeting Room C4.9
Session type: Workshop

The development of new detector systems dedicated to the search of new physics in the underground laboratories is mandatory for exploring the physics beyond the Standard Model. Searches for extremely rare or even not existent processes, such as neutrino-less double beta decays, the decay of the proton, dark matter candidates or processes prohibited by the standard quantum mechanics are extremely important to better understand Nature and Universe, from particle world to the sky (cosmology). The capacity to either set limits for the investigated processes or to, finally, discover them strongly depends on the dedicated detector systems technologies and performances.

In the last 5 years huge progress was achieved both in developing new detector concepts or pushing to the limits the existing ones, by refining the involved technologies. Various detector systems, going from cryogenic solids and large liquid masses, to radiation detectors, such as silicon drift detectors, ultrapure germanium detectors, dedicated photo-multipliers, and particle detectors, such as directional TPC, were developed and some of them are already installed and in data taking at major underground laboratories in the world. Some other detector systems is being optimized for future-generation experiments.

This DEUS workshop will introduce to the non-experts in the Underground Searches of new physics the main physics ideas and motivations for these searches, together with the main technologies for detector systems dedicated to the searches of neutrino-less double beta decays, decay of the proton, dark matter candidates or processes prohibited by the standard quantum mechanics of dark matter.

Introductory talks from experts belonging to experiments currently in operation will review the current status of their detectors and will introduce the challenges which they face in carrying out the physics program and young scientists will present specific topics related to their research in the field. Future plans for the development and use of new technologies which could either improve or revolutionize the underground physics will be discussed.

The interested participants, in particular young scientists, are encouraged to participate and to present their research activity and results, especially focused on the new ideas for the development of detectors dedicated to the underground searches of new physics.

The design of the project named CYGNO is presented. CYGNO is a new proposal supported by INFN, the Italian National Institute for Nuclear Physics, within CYGNUs proto-collaboration (CYGNUS-TPC) that aims to realize a distributed observatory in underground laboratories for directional Dark Matter (DM) search. CYGNO is one of the first prototypes in the road map to 100-1000 m3 of CYGNUs and will be located at the National Laboratory of Gran Sasso (LNGS), in Italy, aiming to make significant advances in the technology of single phase gas-only time projection chambers (TPC) for the application to the detection of rare scattering events. In particular it will focus on a read-out technique based on triple Gas Electron Multiplier (GEM) amplification of the ionization and on the visible light collection with a sub-mm position resolution sCMOS (scientific COMS) camera. This type of readout - in conjunction with a fast light detection - will allow on one hand to reconstruct 3D direction of the tracks, offering accurate sensitivity to the source directionality and, on the other hand, a high particle identification capability very useful to distinguish nuclear recoils. The final goal is to deliver a high resolution 1 cubic meter detector as prototype innovative detector for directional DM detection.
