Description
We report on recent results from the application of InGrids in the CAST experiment at CERN searching for solar axions and solar chameleons. InGrids employ Micromegas-like gas amplification using a highly pixellated CMOS readout chip as charge-collecting anode. An InGrid detector has successfully taken data in the CAST setup using the Abrixas X-ray telescope in late 2014. Operation experience and first results from this data taking period will be presented. A multi-variate technique for background reduction will be shown. An outlook will be given towards further improvements of the setup in terms of X-ray efficiency and active background suppression. Also, potential application of InGrids as X-ray detectors in IAXO will be discussed.
