Modular and Scalable Multi-Timepix3 Readout System — •Thomas Block, Klaus Desch, Markus Gruber, Jochen Kaminski, and Tobias Schiffer — Universität Bonn

The Timepix3 chip of the Medipix3 collaboration is a highly granular pixel chip. It can be used in combination with different detector components, e.g. with a bump bonded silicon pixel sensor, with a photolithographically postprocessed MicroMegas gas amplification stage (InGrid), or with a micro-channel plate (MCP). Therefore different detectors can be built, which can be used for various applications like beam telescopes, X-Ray detectors for axion search and polarimetry and neutron detectors. For these different detectors we are developing a fully open source solution: the Timepix3 readout system. It enables us to adapt to the different requirements (low- to high-rate events and single- to multi-chip design) efficiently. The system, which already has been used in test runs, supports different FPGA boards, which cover the different requirements. The Scalable Readout System (SRS), being one of them, together with of our own PCB designs, supports low- to medium-rate applications. Based on the basil framework, developed at SILAB Bonn, the firmware is written in Verilog and the software is written in Python. For the control system both a graphical user interface and a command-line interface have been developed.

In this talk I will present the readout and control system and the recent development from single-chip to multi-chip support. Also I will show the needed functionality like calibration, equalisation, readout and monitoring.
