Barcelona Techno weeks are a series of meeting point events around a technological topic of interest for both academia and industry. They include comprehensive multidisciplinary keynote presentations by world experts that are combined with networking activities to foster collaboration among participants. As the first Techno week in 2016, the third edition includes a course on solid state radiation detection, from physics and electronics fundamentals to the state-of-the-art methods in radiation (X-ray, gamma-ray, charged particle) and visible light detection and applications. Lectures, a participant poster session and presentations from industry professionals are combined with social events. Moreover, this year’s program includes a series of laboratories on medical imaging, hybrid pixel detectors and Monte Carlo simulation tools for photon-electron interactions with matter. The objectives of the course are: Explain fundamentals of interaction of radiation with matter and signal formation. Understand different solid state radiation and photon detection technologies. Review detector analog and digital pulse processing readout circuits. Provide an insight of packaging and interconnect technologies. Survey the use of radiation and photon detectors in industrial applications. Present new trends in radiation and photon detection. The event is aimed at researchers, postdocs, PhD students and industry professionals, working in related fields: particle detectors, astronomy, space, medical imaging, scientific instrumentation, material analysis, neutron imaging, process monitoring and control, etc. The meeting offers a good opportunity for young researchers to meet with senior experts from academia and industry.
