These dark energy candidates could be produced in the Sun and stream unimpeded to Earth. The KWISP detector installed on the CAST axion search experiment at CERN looks for tiny displacements of a thin membrane caused by the mechanical effect of solar chameleons. The displacements are detected by a Michelson interferometer with a homodyne readout scheme. The sensor benefits from the focusing action of the ABRIXAS X-ray telescope installed at CAST, which increases the chameleon flux on the membrane. A mechanical chopper placed between the telescope output and the detector modulates the incoming chameleon stream. We present the results of the solar chameleon measurements taken at CAST in July 2017, setting an upper bound on the force acting on the membrane of 80pN at 95% confidence level. The detector is sensitive for direct coupling to matter 104 = ßm = 108, where the coupling to photons is locally bound to ß¿ = 1011. 000095042 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/MINECO-FEDER/FPA2011-24058$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2013-41085-P 000095042 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000095042 590__ $$a4.473$$b2019 000095042 591__ $$aASTRONOMY & ASTROPHYSICS$$b17 / 68 = 0.25$$c2019$$dQ1$$eT1 000095042 592__ $$a1.459$$b2019 000095042 593__ $$aAstronomy and Astrophysics$$c2019$$dQ1 000095042 593__ $$aSpace and Planetary Science$$c2019$$dQ2 000095042 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/submittedVersion 000095042 700__ $$aBaier, J. 000095042 700__ $$aBarth, K. 000095042 700__ $$aBaum, S. 000095042 700__ $$aBayirli, A. 000095042 700__ $$aBelov, A. 000095042 700__ $$aBräuninger, H. 000095042 700__ $$aCantatore, G. 000095042 700__ $$0(orcid)0000-0003-2264-2306$$aCarmona, J.M.$$uUniversidad de Zaragoza 000095042 700__ $$0(orcid)0000-0003-3532-7540$$aCastel, J.F.$$uUniversidad de Zaragoza 000095042 700__ $$aCetin, S.A. 000095042 700__ $$0(orcid)0000-0002-8921-910X$$aDafni, T.$$uUniversidad de Zaragoza 000095042 700__ $$aDavenport, M. 000095042 700__ $$aDermenev, A. 000095042 700__ $$aDesch, K. 000095042 700__ $$aDöbrich, B. 000095042 700__ $$aFischer, H. 000095042 700__ $$aFunk, W. 000095042 700__ $$0(orcid)0000-0002-7399-7353$$aGarcía, J.A. 000095042 700__ $$aGardikiotis, A. 000095042 700__ $$0(orcid)0000-0003-0800-1588$$aGarza, J.G. 000095042 700__ $$aGninenko, S. 000095042 700__ $$aHasinoff, M.D. 000095042 700__ $$aHoffmann, D.H.H. 000095042 700__ $$0(orcid)0000-0001-6327-9369$$aIguaz, F.J. 000095042 700__ $$0(orcid)0000-0003-1163-1687$$aIrastorza, I.G.$$uUniversidad de Zaragoza 000095042 700__ $$aJakovcic, K. 000095042 700__ $$aKaminski, J. 000095042 700__ $$aKaruza, M. 000095042 700__ $$aKrieger, C. 000095042 700__ $$aLakic, B. 000095042 700__ $$aLaurent, J.M. 000095042 700__ $$0(orcid)0000-0002-5352-1884$$aLuzón, G.$$uUniversidad de Zaragoza 000095042 700__ $$aMaroudas, M. 000095042 700__ $$aMiceli, L. 000095042 700__ $$aNeff, S. 000095042 700__ $$aOrtega, I. 000095042 700__ $$aOzbey, A. 000095042 700__ $$aPivovaroff, M.J. 000095042 700__ $$aRosu, M. 000095042 700__ $$0(orcid)0000-0002-3253-7027$$aRuz, J. 000095042 700__ $$aChóliz, E.R. 000095042 700__ $$aSchmidt, S. 000095042 700__ $$aSchumann, M. 000095042 700__ $$aSemertzidis, Y.K. 000095042 700__ $$aSolanki, S.K. 000095042 700__ $$aStewart, L. 000095042 700__ $$aTsagris, I. 000095042 700__ $$aVafeiadis, T. 000095042 700__ $$aVogel, J.K. 000095042 700__ $$aVretenar, M. 000095042 700__ $$aYildiz, S.C. 000095042 700__ $$aZioutas, K. 000095042 7102_ $$12004$$2X$$aUniversidad de Zaragoza$$bDpto.
