This report outlines the origin of aberrations in a Low Energy Electron Microscope (LEEM) and how to measure and automatically correct them. The aberrations in a LEEM are mainly caused by the cathode objective lens and are a limiting factor for the achievable resolution. To optimise the resolution of …

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 …

When treating cancer by radiation therapy it is always the goal to irradiate the tumour as much as possible and to spare the healthy tissue around it. For this a new type of radiation therapy called Volumetric Modulated ARC Therapy (VMAT) has been developed. During VMAT treatment the radiation machine …
