Increasing oil and energy demand asks for higher efficiency when it comes to oil recovery. To increase oil recovery efficiency, pore-scale mechanisms during waterflooding, a common recovery method, have to be better understood. This provides knowledge on the dynamic process during imbibition, which …

Research has been done to improve the understanding the self-heat effect, due to power dissipation, of temperature-dependant resistors in the VSL water calorimeter. A custom measurement program has been written to be able to control and read out three Agilent 3458A digital multimeters (DMMs). With these …

Vakintegratie is een hot item! Binnen het bètadomein is dit echter een moeizaam proces. Een kanshebber voor een succesvolle geïntegreerde aanpak is “leren door ontwerpen”. Een manier die aansluit bij nieuwe vakken als NLT en O&O en tevens bij de ontwikkeling van Technasia een belangrijke rol kan spelen. …

Optical Coherence Tomography (OCT) is an imaging technique for collecting depth resolved information in human tissue based on an interferometer. With an imaging depth of between 1 and 2 mm, OCT is only used to investigate (near) surfaces. But with an axial (depth) resolution of between 2 and 10 μm, and …

The treatment of tumours in cancer patients have become more advanced and thus more complex. The verification of the dose distribution, calculated by clinical physicists, have thus become more complicated. VSL has started the development on measurements of absolute dose distributions in an antrhopomorphic …

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 …

In the medical community, X-rays are an important tool in imaging the human body. In principle X-ray images are 2 dimensional images. By measuring such X-ray images at multiple angles, one can construct the 3 dimensional inner structure of the sample. This 3 dimensional structure is created by applying …

The characteristics of a hydrogen plasma in an inductively coupled RF plasma setup were studied using a double Langmuir probe and an optical emission spectrometer. At various settings for the gas pressure, gas ow, RF power and probe position, values were obtained for the electron temperature and plasma …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …

Within the semiconductor industry the demand for ever decreasing chip and resistor sizes has forced the use of extreme ultraviolet (EUV) waves in lithography machines. The older generation lithography machines used lenses to focus the waves. These lenses aren't transparent for EUV waves with a wavelength …
