AbstraktAbstract
This proposal describes a technique to expand the confidence limits of WIMP detection towards energies well below the usually assumed 1 GeV. The combination of Timepix4 chips with micropattern gaseous detector (MPGD) technology offers a new scalable, pixellated charge readout for gaseous time projection chambers (TPC). For low energy dark matter searches this is a cost effective replacement of the commonly used solutions of light collection by CMOS cameras - compromised at low energy depositions due to the very faint light emissions in the gas - or other charge readout systems that have a much coarser granularity.
