Astroparticle, Particle and Space Physics, Detectors and Medical Physics Applications Proceedings of the 11th Conference, Villa Olmo, Como, Italy, 5-9 October 2009

The exploration of the subnuclear world is done through increasingly complex experiments covering a wide range of energy and performed in a large variety of environments from particle accelerators, underground detectors to satellites and space laboratory. The achievement of these research programs calls for novel techniques, new materials and instrumentation to be used in detectors, often of large scale. Therefore, fundamental physics is at the forefront of technological advance and also leads to many applications. Among these, medical applications have a particular importance due to health and social benefits they bring to the public.
