Embedding the Timepix4 in Micro-Pattern Gaseous Detectors
Abstract
The combination of Micro-Pattern Gaseous Detectors (MPGDs) and pixel charge readout enables specific experimental opportunities. Using the Timepix4 for the readout is advantageous because of its size (around 7 cm^2 active area) and its Through Silicon Vias. The latter enables to connect to the Timepix4 from the back side. Thus, it can be tiled on four sides, allowing it to cover large areas without loss of active area. Here, the first results of reading out MPGDs with the Timepix4 are presented. Measurements with a Gas Electron Multiplier (GEM) detector show that event selection based on geometrical parameters of the interaction is possible, X-ray imaging studies can be performed, as well as energy and time-resolved measurements. In parallel, the embedding of a Timepix4 into a micro-resistive Well (uRWell) amplification structure is explored. The first mechanical tests have been successful. The status of the electrical functionality is presented, as well as simulation studies on the signal induction in such a device.
