This paper describes the robustness determination and optimization of L-cysteine addition for total mercury content determination by Instrumental Neutron Activation Analysis (INAA). Instrumental Neutron Activation Analysis is an analysis technique to measure concentrations of chemical elements regardless …

Introduction: Body composition and body circumferences are tools for health professionals to predict health risks and to evaluate a patient’s treatment. The BODPOD® is a validated device to determine body composition, but it is expensive and therefore not accessible for a lot of health professionals. …

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 …

Dit rapport focust op het kiezen, ontwerpen, realiseren en uiteindelijk testen van een analysemethode die de verspreiding van houtskool in een cold flow wervelbed (verbrandingskamer) kan bepalen. Deze coldflow opstelling is een simulatie van MILENA met 22MW thermische input. Tijdens dit afstudeerproject …

A Quad Focus GridPix Gaseous Tracking Detector is under construction, to allow calibration and test beam measurements to validate the working principles of the (quad) GridPix detectors while using a focused electric field. The development is well on its way: both measurements should be able to be conducted …

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 …

Nuclear fusion is seen as one of the future technologies for roducing electrical power. In a hot and con ned plasma deuterium and tritium will melt together and form a helium nucleus and a neutron. This process produces a total of 17.6 MeV energy. In the plasma instabilities occur. Suppression of these …

The recently developed HyperCollar applicator was specifically designed to heat tumors in the head and neck region. The applicator uses twelve antennas to create an EM interference pattern, which applies heat to the target area. Patients' position and movement needs to be tightly monitored and controlled …

In this report the properties of the E-field sheet have been measured. Also the connection between the E-field sheet and the pc has been developed. For visualisation of the data a GUI has been made in Matlab which also reads out the data from the DAQ card. Before a measurement on the clinical equipment …
