  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
and the identification of the coherent neutrino scattering (CNS) from the Sun.
CYGNO is one of the first prototypes in the road map to 100-1000 m^3 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
Micro Pattern Gas Detector (MPGD) 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.
