  2. 1. Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design

    Author : Matthias Burza; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wakefield; ultra-relativistic; ultra-intense; TNSA; Terawatt; sheath; proton; polarimetry; plasma mirror; plasma; Petawatt; particle; oscillation; Normarski; micromachining; LWFA; laser; interferometry; electron; contrast; acceleration; bubble; Fysicumarkivet A:2012:Burza;

    Abstract : Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the ~10 MeV regime. READ MORE

    Abstract : Light is the primary source of energy on our planet and has been a significant driver in the evolution of human society and technology. Light finds applications in two-dimensional (2D) photolithography and three-dimensional (3D) printing, where a pattern is transferred to a material of interest by ultraviolet (UV) light exposure, and in laser scribing and cutting, where high power lasers are used to pattern the surface of objects or cut through the bulk of the material of interest.

    Abstract : Today there is growing interest in research on microfluidicsystems, e.g., for chemical analysis systems and microdosagesystems. One of the basic components in microfluidic systems ismicropumps. READ MORE

  7. 5. MM-wave integrated RF-MEMS tunable cavity resonators, filters and ultra-low phase-noise oscillators

    Author : Dragos Dancila; Isabelle Huynen; Universite catholique de Louvain (UCL); []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Within the Microelectronics Industry, the core research is focused on the realization of the Moore's law, which states that circuit density doubles every 24 months, shaping the framework of the More of Moore paradigm. However, Moore's law is expected to end, as devices are reaching limitations inherent to the approach of the atomical dimensions. READ MORE
