Instruments

The instrumentation programme at APEX satisfies both the need of having a test-bed for the development of state-of-the-art equipment, as well as providing general use instruments to cover a broad range of scientific needs. The facility instruments try to fill...

Science with APEX

Many of the most interesting objects in the Universe are difficult to observe from our Earth. The light emitted at optical and infrared wavelengths is blocked by interstellar matter between the source and us, so many exciting regions in space...

Welcome to Atacama Pathfinder EXperiment (APEX)

Welcome to the APEX web site. You will find here all about our project and the amazing 12-m radio telescope that we operate in northern Chile. APEX is located in a privileged location, on the “Llano de Chajnantor”, at 5100 m. above the sea level. At such high altitude, the dry atmosphere of the Atacama desert opens up a unique window to observe the millimetre and sub-millimetre light. The versatile set of state-of-the-art instrumentation onboard APEX is at the service of researchers around the world, to learn more about the cold and the dusty Universe.
