4. 3. Direct writing with an MeV proton beam: Development and Applications

   Författare :Vaida Auzelyte; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; direct writing; beam control; Physics; Fysik; Teknik; Technological sciences; proton beam; lithography; Fysicumarkivet A:2006:Auželytė;

   Sammanfattning : 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. LÄS MER

5. 4. Development of Techniques for 3D Imaging with Focused Ion Beams - Hydrogen Depth Profiling and Microtomography with Applications in Geology

   Författare :Marie Wegdén; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrogen analysis; Depth profiling; Ion beam analysis; Nuclear microprobe; Physics; Nuclear physics; Fysik; Fysicumarkivet A:2007:Wegdén; Kärnfysik; Tomography; 3D Imaging;

   Sammanfattning : 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. LÄS MER

7. 5. Development of New Experimental Facilities at the Lund Nuclear Microprobe Laboratory
