A new laser-plasma X-ray source for microscopy and lithography

Popular Abstract in Swedish Avhandlingen beskriver en ny typ av kompakt röntgenkälla baserad på ett laser-producerat plasma (LPP). I motsats till konventionella LPP används inte fasta material som strålmål för den fokuserade laserstrålen. I stället används mikroskopiska vätskedroppar eller vätskestrålar. Detta medför en mycket väsentlig minskning av det skräp (debris) som skickas ut från plasmat. A new high-brightness source for soft X-rays and EUV-radiation has been developed. This laser-plasma source utilizes a microscopic liquid droplet or jet as target. The result is a reduction of debris emission by several orders of magnitude compared to conventional laser plasmas. The minute amounts of residual ionic/atomic debris can be obstructed by filters or a localized gas shield. Target liquid

Micro- and Nanostructures for Studies of Model Biological Systems

Popular Abstract in English Small Devices to Study Small Biology Biological components that are smaller than a cell are difficult to study directly. A great deal of work has been done developing devices and techniques that allow scientists to control and observe sub-cellular biology. In this thesis I, along with my colleagues, have made a number of devices that give us control over the small bioloSub-cellular biological components are complex systems that work together to control and maintain cellular activity and health. It is useful to study the basic elements that constitute the sub-cellular components using model systems, which mimic certain parts of the overall system, in order to better understand the system as a whole. Here we present a number of tools, which enable the study of a f
