Towards a mobile and low-power platform for pixel detectors to be used in educational settings — •Oliver Keller1,2, Sascha Schmeling1, Andreas Müller2, and Mathieu Benoit2 — 1CERN, Geneva, Switzerland — 2University of Geneva, Switzerland
Pixel detector readout chips like the Timepix3 (developed within the Medipix collaboration hosted at CERN) offer numerous advantages for novel physics experiments also in educational settings. This contribution details ongoing development of data acquisition electronics and software geared towards learning environments. The Timepix3 chip is connected to an embedded multi-core processor which consumes considerably less power than the pixel detector itself enabling mobile applications. This novel processor-based approach allows faster development cycles and an overall simplified system design compared to a traditional FPGA-based solution. A compact bias supply circuit for silicon sensors is included which fulfils corresponding safety requirements for accessible parts like the sensor surface. Data output to computers or mobile devices is provided via wired and wireless ethernet. Software features of the platform are chosen to support guided experiments as well as inquiry-based learning in indoor and outdoor scenarios.
