  1. 1. PERFORMANCE OF THE PHOTODETECTOR FOR THE ACTIVE SHIELD OF THE COSI SPACE TELESCOPE

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Daniel Álvarez Franco; [2022]
    Keywords : Geant4; scintillation; BGO; CsI; simulation; COSI; telescope; photoelectric effect;

    Abstract : The COmpton Spectrometer and Imager (COSI) is a space telescope that aims to study the soft gamma regime (0.2-5 MeV), capable of performing spectroscopy, imaging and polarimetry of cosmic gamma sources. READ MORE

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

    University essay from Uppsala universitet/Institutionen för materialvetenskap

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

    Abstract : 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. READ MORE

  4. 3. Preamplifier Design for Active Electrodes in Single-Channel EEG Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Thorir Marwan Abed; [2018]
    Keywords : Electroencephalography EEG ; single-channel; active electrode; current feedback instrumentation amplifier CFIA ; DC servo loop DSL ; portability.; Elektroencefalografi EEG ; singelkanal; aktiv elektrod; strömåterkoppling instrumentförstärkare; DC servo loop DSL ; bärbarhet.;

    Abstract : The implementation of portable electroencephalography (EEG) systems has been known to be complex. During ambulation, the integrity of recorded EEG signals is often impaired by motion artifacts and the time and effort required to set up the system is excessive. READ MORE

  5. 4. Model based pulse shaping for detection of gamma rays

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Fredrik Ödmark; [2017]
    Keywords : pulse shaping; FWHM; CR-RC; electric noise model; analyse drill samples; gamma ray detector; matched filter; custom filter; clustering;

    Abstract : To analyse drill samples in a mine, a scanner that uses a gamma ray detector can be used. The scanner can analyse the drill sample to quickly see the elements present in the sample without destroying it. READ MORE

  6. 5. Extraction of energy and time from pile-up pulses with fast sampling ADC analysis techniques

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Anton Roth; [2016]
    Keywords : moving window deconvolution; alpha-decay; short-lived nuclei; digital pulse processing; Superheavy elements; decay paths; Physics and Astronomy;

    Abstract : Debates of whether Z=114 and N=184 are the next magic numbers in nuclear physics have existed since the earliest predictions made in the 1960s. Until these days they have not been firmly established. READ MORE
