ATLAS is a very high-energy detector for the Large Hadron Collider (LHC) at CERN. The superconducting magnet used to provide the required magnetic field consists of four sub-systems: a central solenoid and a very large toroidal magnet comprising two end-cap magnets and the barrel toroid magnet. The associated cryogenic system, currently in the final specification and procurement phase has been ...

Mechanical applications for polymers at cryogenic temperatures are extremely limited due to decreased atomic mobility and ductility, resulting from glass transitions above the regime (<120 K). As such, polymeric materials known cracking low fatigue life. Crumpling polymer films has been historically researched as a mechanism bypass this brittleness mechanical actuation, but characterization of ...
After a short introduction, the observing capabilities in the near{infrared bands of the camera/spectrograph NICS designed for the TNG are discussed, along with the expected performance in term of limiting magnitudes. The second part of the paper describes some technical details of the project, such as cryogenics, mechanics, and the system which executes data acquisition and control with the re...
