R&D Project 2:
A thin fast hybrid pixel detector system for tracking in high particle densities

Research Objective

In detector regions with very high track densities the unambiguous two-dimensional coordinate measurement capabilities of pixel detectors will be required. However, current hybrid pixel detector technologies are too massive. In this R&D task we will address the design and realization of an advanced light-weight hybrid pixel system optimized for the conditions in hadron physics experiments. The focus is on developing very-low power front-end electronics with high-resolution position, energy loss and timing measurements, and on achieving a minimum system thickness with thinned readout chips connected with advanced bump-bonding or frontier 3D-integration techniques to very thin epitaxial pixel detectors.
