Nike Free 5.0 Uk and Zn Sn Al alloy solutions Large supersaturation
The OPERA experiment is designed to Nike Free 5.0 Uk study the νμ→ντνμ→ντ oscillation observing the ντντ appearance in a pure νμνμ beam over a base line of 732 km from CERN to Gran Sasso Laboratory. The apparatus consists of a lead/emulsion-film target complemented by electronic detectors and muon spectrometers for muon charge and momentum measurements. The tracking inside the magnets is provide by Bakelite RPC chambers in a large scale application. The commissioning of the RPC system ended in August 2006. The paper present the layout of the RPC system and its performances. Polycrystalline silicon thin films have been deposited on borosilicate glass substrates from pure Zn and Zn/Sn/Al alloy solutions. Large supersaturation was achieved by evaporating Zn from the Nike Free Run 2 Uk solution, which created an enormous driving force for initial crystal nucleation. Best properties were obtained for the films deposited from Zn alloy solutions. This was explained by the presence of a liquid medium on the substrate during Zn evaporation, which allowed for silicon solute mobility and crystallite growth and thus forming large grained crystals on the glass substrate.
