3. Direct writing with an MeV proton beam: Development and Applications
Abstract : This thesis presents work aimed at the development and application of a new lithography system for direct material patterning with the MeV proton beam at the Lund Nuclear Microprobe (NMP) facility. MeV proton beams are advantageous for use as a patterning tool due to their deep and well defined penetration through matter and their highly local energy deposition. READ MORE

4. Assembling of a low energy ion beam analysis facility and use of Nuclear Microprobe techniques in geological studies
Abstract : In about four decades, ion beam analysis (IBA) techniques have evolved to become well established analytical techniques for routine analysis in archaeological, bio-medical, geological and environmental sciences. They basically make use of the different interactions of a high energy ion beam (of few MeV/amu) with the specimen matter so they pressupose the use of a particle accelerator. READ MORE

5. Development of Techniques for 3D Imaging with Focused Ion Beams - Hydrogen Depth Profiling and Microtomography with Applications in Geology
Abstract : In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. READ MORE
