  1. 1. An Inexpensive Alpha Spectrometer Based on a p-i-n Photodiode : Making Advanced Particle Detectors From Common Commercial Components

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Elias Arnqvist; [2022]
    Nyckelord :Alpha spectroscopy; alpha particle; particle detector; radiation detector; p-i-n diode; PIN diode; photodiode;

    Sammanfattning : The purpose of this project was to design, construct, and evaluate an alpha spectrometer based on an inexpensive p-i-n photodiode as a radiation detector. The BPX-61 p-i-n photodiode was selected and calculated to have a 93 µm wide sensitive volume at 25 V reverse bias. LÄS MER

  3. 2. High speed communication

    H-uppsats,

    Författare :Robert Legeza; Johan Bodin; [2019-07-03]
    Nyckelord :Grundläggande vetenskaper; Hållbar utveckling; Informations- och kommunikationsteknik; Elektronik; Basic Sciences; Sustainable Development; Information Communication Technology; Electronics;

    Sammanfattning : This master thesis examines the problems that occur for high speed serial communication. The thesis focus on serial transmission through backplane, coaxial cable and optical fiber. Experiments using RocketIOTM GTP and GTX transceivers are performed at data rates of up to 5 Gbit/s.

  4. 3. High voltage transient protection for automotive

    Uppsats för yrkesexamina på avancerad nivå, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Viktor Lindholm; [2019]
    Nyckelord :Automotive; protection circuit; Load dump; pulse 1; pulse 2a; ISO 16750; ISO 7637; voltage transients; double exponential transient; pulse generator.;

    Sammanfattning : Electronics for automotive needs to be able to handle different situations that can occur on the power line, such as high voltage transients. ISO16750 and ISO-7637 describes different pulses and tests a system needs to be able to handle. LÄS MER

  5. 4. Dynamic Stark Shaping of Molecular Fate

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sharon Berkowicz; [2019]
    Nyckelord :Dynamic Stark effect; Dynamic Stark Control; Oxygen; Photodissociation; Photochemistry; Laser Spectroscopy; Dynamiska Starkeffekten; Dynamisk Starkkontroll; Syre; Fotodissociation; Fotokemi; Laserspektroskopi;

    Sammanfattning : The dynamic (ac) Stark effect refers to the energy shifting of electronic states induced by an oscillating electric field. Conveniently, the magnitude of the ac Stark shift scales with the square of the electric field amplitude, i.e. with light intensity. LÄS MER

  7. 5. Dependency of high-order harmonics to polarisation properties of many-cycle driving fields

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Timothé Ramboazanaka; [2018]
    Nyckelord :Atomic physics; attosecond pulses; high-order harmonic generation; polarisation; polarisation state; electron wave packet trajectory; three-step model; time-dependent schrödinger equation; TDSE; two-colour; selection rules; symmetry; conservation laws; Physics and Astronomy;

    Sammanfattning : Light-matter interactions can be used to probe both light and matter as they yield information on a system's state. On the ultrafast timescale, it is possible to employ these interactions to probe fast-occurring phenomena. LÄS MER
