Modular and scalable Timepix3 readout system — Klaus Desch, •Markus Gruber, Thomasz Hemperek, Jochen Kaminski, Leonie Richarz, and Tobias Schiffer — Physikalisches Institut, Universität Bonn, Nußallee 12, 53115 Bonn

With the highly granular pixel ASIC Timepix3 several different detectors can be built by combining it either with a bump bonded sensor or with a photolithographically postprocessed MicroMegas gas amplification stage (InGrid). With these combinations quite different applications like beam telescopes, X-Ray detectors and neutron TPCs can be realized.

For the detectors to be built with this ASIC that range from single chip to multichip designs and from low- to high-rate applications a modular and scalable readout and control system is needed which can efficiently adapt the different scenarios. The firmware and software are based on the basil framework and as readout system several FPGA boards are supported including the Scalable Readout System (SRS) which offers scalability in low to medium rate multichip applications. Besides the capability of different detector designs the system offers optional monitoring interfaces for different detector parameters.

In this talk I will present the readout and control system and how it scales for the applications. Furthermore, I will show how the modular approach enables several different detector designs and offers the needed functionality like calibration, equalization, readout and monitoring.
