In dit onderzoek zijn de mogelijkheden onderzocht voor alternatieve manieren van daglichttransport in een schoolgebouw, omdat dit een positieve invloed op de werkprestaties heeft. Er zijn oplossingen beschreven om daglicht via een andere weg dan gevelopeningen een ruimte in te leiden zoals intelligente …

The Dutch Transmission System Operator (TSO) TenneT TSO B.V. is planning to build a 2 km to 4 km long 150 kV superconducting cable connection in the Dutch high voltage grid. Superconducting cable systems allow for connections with no external magnetic field which is beneficial due to society's concerns …

A system was designed and assembled to measure the critical temperature of superconductive thin niobium titanium nitride films. The films were produced via a process called sputtering. The parameters used during this process were characterized to produce films with as high as possible critical temperature …

A program that automatically detects auroral events in all-sky images taken by the all-sky camera of IRF has been written. Current programs that automatically detect the aurora in all-sky images using the RGB color system often miss strong aurora and sometimes interprets clouds as aurora. To improve …

Gas-phase diffusion is a widespread process in nature, for example diffusion of pollutants in the atmosphere. A special case of diffusion is the so-called Knudsen diffusion where a gas diffuses in the molecular flow regime. The theory for Knudsen diffusion is well-known therefore, diffusion experiments …

Een bestraalde EBT3 film wordt door middel van een commerciële flatbed scanner uitgelezen. Het is gebruikelijk om deze film te scannen in transmissie modus. De absorptie van de film wordt uitgelezen en omgezet naar een maat voor de dosis in cGy per pixel. Deze dosis wordt met een zekere nauwkeurigheid …

Scanning tunneling microscopy is an important and enabling tool for condensed matter physics and surface science. The low temperature STM in Leiden (Prof. J. Van Ruitenbeek and Prof J. Aarts) is used for research in the field of atomic/molecular electronics and superconductivity. The current low temperature …

A laboratory test setup is built to transfer and actively stabilize an ultrastable signal, obtained from a laser with sub-Hz linewidth, trough a 5 km long fiber link. The fiber noise is measured and compensated via a feedback loop acting on an AOM that can change the frequency (and therefore the phase) …

Research is done on the properties of a niobium superconducting magnetic shield sample (see image below this abstract), its magnetic attenuation; and behaviour around the transition temperature 9.25 K. The attenuation of the magnetic shield sample was measured in a cryogenic setup. This is required to …
