XXV Spreadbury Lecture : Neutrino Oscillations At Work
The observation that the three types of neutrino flavour oscillate among themselves led to the realisation that neutrinos have a very small but non-zero mass. This is extremely important because the supremely successful Standard Model of particle physics had expected, and indeed needed, the neutrinos to have exactly zero mass. Since the discovery of neutrino oscillations over the last 15 years, the parameters of the oscillations have been sufficiently well measured to turn neutrino oscillations into a tool for learning more about the elusive neutrino. I will explain the concept of neutrino oscillations, and report on the recent results from around the world and the new challenges now facing researchers trying to infer the remaining unknown neutrino properties. I will talk briefly about an exciting new project on the horizon for the very near future.

Quality assurance measurements during the ATLAS Insertable B-Layer production and integration
The ATLAS Detector is one of the four big particle physics experiments at CERN's LHC. Its inner tracking system consisted of a 3-Layer silicon Pixel Detector (~ 80M readout channels) in the first run (2010-2012) and has been upgraded by an additional layer over the last two years. The Insertable B-Layer (IBL) adds ~12M readout channels for improved vertexing, tracking robustness and b-tagging performance for the upcoming runs before the high luminosity of the LHC will take place. The active part of the detector is roughly 66cm long and consists of 14 parylene coated carbon foam support structures, so-called staves, at an average distance of 33.25mm away from the beam. The IBL includes new sensor and readout chip designs finding their first application in high energy physics experiments. Production accompanying measurements as well as preliminary results after integration into the ATLAS Detector, right before the start of the second LHC run, will be presented and discussed.
