Modular and scalable Timepix3 readout system — Klaus Desch, •Markus Gruber, Tomasz Hemperek, Jochen Kaminski, 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, with a photolithographically postprocessed MicroMegas gas amplification stage (InGrid) or with a micro-channel plate (MCP). With these combinations quite different applications like beam telescopes, X-ray detectors for axion search and polarimetry and neutron detectors can be realised.

Based on the basil framework we are developing a Timepix3 readout system which can efficiently adapt these applications that range from single chip to multi-chip designs and from low- to high-rate applications. Furthermore we are implementing a flexible monitoring system that is needed to support a range of data sources depending on the detector. The hardware consists of our own PCB designs and a support of multiple FPGA boards including the Scalable Readout System (SRS) which offers scalability in low to medium rate multi-chip applications.

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, equalisation, readout and monitoring.
