Assink, J.D. (author), Waxler, R. (author), Smets, P.S.M. (author), Evers, L.G. (author)In January 2011, the state of the polar vortex in the midlatitudes changed significantly due to a minor sudden stratospheric warming event. As a result, a bidirectional duct for infrasound propagation developed in the middle atmosphere that persisted for 2 weeks. The ducts were due to two zonal wind jets, one between 30 and 50 km and the other...journal article 2014

De Visser, P.J. (author), Baselmans, J.J.A. (author), Bueno, J. (author), Llombart, N. (author), Klapwijk, T.M. (author)In a superconductor, in which electrons are paired, the density of unpaired electrons should become zero when approaching zero temperature. Therefore, radiation detectors based on breaking of pairs promise supreme sensitivity, which we demonstrate using an aluminium superconducting microwave resonator. Here we show that the resonator also...journal article 2014

Haber, A. (author)Extreme UltraViolet (EUV) lithography is a new technology for production of integrated circuits. In EUV lithographic machines, optical elements are heated by absorption of exposure energy. Heating induces thermoelastic deformations of optical elements and consequently, it creates wavefront aberrations. These Thermally Induced Wavefront...doctoral thesis 2014
