  1. 1. 1kW Class-E solid state power amplifier for cyclotron RF-source

    University essay from Uppsala universitet/FREIA

    Author : Stefan Book; [2018]
    Keywords : Class-E; LDMOS; high efficiency; high power; VHF; power amplifier; accelerator; cyclotron;

    Abstract : This thesis discusses the design, construction and testing of a highefficiency, 100 MHz, 1 kW, Class-E solid state power amplifier. The design was performed with the aid of computer simulations using electronic design software (ADS). The amplifier was constructed around Ampleon's BLF188XR LDMOS transistor in a single ended design. READ MORE

  3. 2. A Reductive Reading of the Tractatus

    University essay from Umeå universitet/Institutionen för idé- och samhällsstudier

    Author : Stefan Karlsson; [2014]
    Keywords : Nonsense; Tractatus; reductive;

  4. 3. Temperature and concentration dependence of hydrogen diffusion in vanadium measured by optical transmission

    University essay from Uppsala universitet/Materialfysik

    Author : Stefan Book; [2014]
    Keywords : Hydrogen diffusion; Vanadium; Metal hydride; Hydrogen storage; Hydrogen economy;

    Abstract : Hydrogen diffusion is investigated in a 50 nm film of vanadium and a vanadium superlattice. Diffusion constants for three different temperature and pressure pairs are determined for the 50 nm film. The diffusion constants for the temperature and pressure pairs are determined to be 4.5 $\pm$ 0. READ MORE
