Inside transverse magnetic fields, axions can be converted into X-rays, which can be detected by X-ray detectors. The expected energy of the signal in CAST is in the 1-10 keV range. Low noise and low background detectors are necessary to increase the sensitivity of the experiment. Micro Mesh Gaseous Structure (micromegas) detectors have been used in CAST since the beginning, providing good energy and spatial resolution for CAST's needs. CAST has been intensely studying micromegas detectors to develop new technologies. Initially, CAST detectors consisted of a micromegas, a Time Projection Chamber (TPC) and a Charged Couple Device (CCD), however the improvements in micromegas technologies encouraged CAST to replace the TPC with 2 new micromegas detectors. In some periods during CAST run, ultra low background has been observed in one of the micromegas detectors and it is being investigated through simulations and laboratory tests carried out at Canfranc Underground Laboratory. If this low background is indeed not a systematic effect, it can open new possibilities on rare event searches. 000129427 536__ $$9info:eu-repo/grantAgreement/EC/FP7/ 240054/EU/Novel Developments in Time Projection Chambers (TPCs) for Rare Event Searches in Underground Astroparticle EXperiments/TREX$$9info:eu-repo/grantAgreement/ES/MICINN/CPAN-CSD2007-00042$$9info:eu-repo/grantAgreement/ES/MICINN/FPA2008-03456 000129427 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000129427 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000129427 700__ $$aAune, S. 000129427 700__ $$0(orcid)0000-0002-8921-910X$$aDafni, T.$$uUniversidad de Zaragoza 000129427 700__ $$aDavenport, M. 000129427 700__ $$aFanourakis, G. 000129427 700__ $$aFerrer-Ribas, E. 000129427 700__ $$aGalán, J. 000129427 700__ $$0(orcid)0000-0002-7399-7353$$aGarcía, J.A.$$uUniversidad de Zaragoza 000129427 700__ $$aGardikiotis, A. 000129427 700__ $$0(orcid)0000-0003-0800-1588$$aGarza, J.G.$$uUniversidad de Zaragoza 000129427 700__ $$aGeralis, T. 000129427 700__ $$aGiomataris, I. 000129427 700__ $$0(orcid)0000-0002-1770-8940$$aGómez, H. 000129427 700__ $$aIguaz, F.J. 000129427 700__ $$0(orcid)0000-0003-1163-1687$$aIrastorza, I.G.$$uUniversidad de Zaragoza 000129427 700__ $$aPapaevangelou, T. 000129427 700__ $$aRodríguez, A. 000129427 700__ $$0(orcid)0000-0002-3253-7027$$aRuz, J. 000129427 700__ $$0(orcid)0000-0002-5225-3953$$aTomás, A.$$uUniversidad de Zaragoza 000129427 700__ $$aVafeiadis, T. 000129427 7102_ $$12004$$2X$$aUniversidad de Zaragoza$$bDpto.
