Description

The International Axion Observatory (IAXO) is a proposed 4th generation axion helioscope that will look for axions and ALPs originating in the Sun via the Primakoff conversion of the solar plasma photons. The baseline detection technique for IAXO are ultra-low background Time Projection Chambers (TPC) with a thin window for the entrance of x-rays and pixelated Micromegas readout, manufactured with the microbulk technique. We will describe the latest results with one such detector in the IAXO pathfinder detection system in operation at the CERN Axion Solar Telescope (CAST), where it has been combined with an x-ray telescope. The prospects to reach levels of background below 10^-7 c/keV/cm2/s needed for IAXO will be discussed, to be demonstrated by a prototype detector and shielding that is now under construction at the Zaragoza University. This activity is part of the IAXO-D0 project to prove the detector experimental parameters for IAXO.
