Abstract: An air-conditioning system for an aircraft has a fresh air line, a recirculation device, an air-mixing device, an air distribution system with multiple cabin air outlets, and a control unit. The control unit is designed to determine or to receive flight-specific parameters characterizing the flight state of the aircraft, and to determine or to receive environment-specific parameters which characterize an air quality in the environment of the aircraft. A first operating state of the air-conditioning system is brought about in the case of a predefined limit value of at least one environment-specific parameter being exceeded, and a second operating state of said system is brought about during a second flight state, which is outside the first flight state. In the second operating state, the fresh air line is fluidically connected to the air-mixing device, and in the first operating state, the fresh air line is separated from the air-mixing device.

Abstract: A Ga-containing and Cu-containing sputtering target has a Ga content of from 30 to 68 at %. The sputtering target contains only CuGa2 as Ga-containing and Cu-containing intermetallic phase or the proportion by volume of CuGa2 is greater than the proportion by volume of Cu9Ga4. The sputtering target is advantageously produced by spark plasma sintering or cold gas spraying. Compared to Cu9Ga4, CuGa2 is very soft, which aids the production of defect-free sputtering targets having homogeneous sputtering behavior.
