The experiment

The International Axion Observatory is a new generation axion helioscope and its main goal is to detect axions (or other similar particles) potentially emitted by the Sun’s core in large quantities. Axions are hypothetical particles proposed in extensions of the Standard Model of Particle Physics. Their existence in not proved experimentally but there are strong theoretical reasons to suspect it. Also, they could solve the problem of the Dark Matter of the Universe.

IAXO will be equipped with low-background x-ray detectors developed at UNIZAR. These detectors are time projection chambers read with novel readout planes called Micromegas.
