=== GridPix detector ===
In 2016, The GridPix detector was installed to detect the [[soft X-rays]] (energy range of 200&nbsp;eV to 10&nbsp;KeV) generated by [[Chameleon particle|solar chameleons]] through the primakoff effect. During the search period of 2014 to 2015 the detected signal-to-noise ratio was below the required levels.<ref name=":6">{{cite journal | last1=Anastassopoulos | first1=V. | last2=Aune | first2=S. | last3=Barth | first3=K. | last4=Belov | first4=A. | last5=Bräuninger | first5=H. | last6=Cantatore | first6=G. | last7=Carmona | first7=J.M. | last8=Castel | first8=J.F. | last9=Cetin | first9=S.A. | last10=Christensen | first10=F. | last11=Dafni | first11=T. | last12=Davenport | first12=M. | last13=Dermenev | first13=A. | last14=Desch | first14=K. | last15=Döbrich | first15=B. | last16=Eleftheriadis | first16=C. | last17=Fanourakis | first17=G. | last18=Ferrer-Ribas | first18=E. | last19=Fischer | first19=H. | last20=Funk | first20=W. | last21=Garc𝚤a | first21=J.A. | last22=Gardikiotis | first22=A. | last23=Garza | first23=J.G. | last24=Gazis | first24=E.N. | last25=Geralis | first25=T. | last26=Giomataris | first26=I. | last27=Gninenko | first27=S. | last28=Hailey | first28=C.J. | last29=Hasinoff | first29=M.D. | last30=Hoffmann | first30=D.H.H. | last31=Iguaz | first31=F.J. | last32=Irastorza | first32=I.G. | last33=Jakobsen | first33=A. | last34=Jacoby | first34=J. | last35=Jakovčić | first35=K. | last36=Kaminski | first36=J. | last37=Karuza | first37=M. | last38=Kostoglou | first38=S. | last39=Kralj | first39=N. | last40=Krčmar | first40=M. | last41=Krieger | first41=C. | last42=Lakić | first42=B. | last43=Laurent | first43=J.
