Spacecraft entering the Earth's atmosphere from space are enveloped by a plasma layer containing highly mobile electrons that cause attenuation of electromagnetic waves, often leading to a loss of command, communication and telemetry signals, which is commonly referred to as the “blackout period”. The blackout period may last up to several(More)
Binary mixtures of ultracold atoms are of great interest in the research field of quantum optics and are studied by several groups aiming at different applications. This paper works with rubidium and caesium, which are simultaneously stored in a magnetic trap. Species-selective microwave cooling is used on the rubidium groundstate hyperfine transition.(More)
