• Robustness of radiation beam profile measurements 

  Nykänen, Topi (2023)

  In this master’s thesis, profile measurements of PTW Semiflex 3D and PTW Semiflex ionisation chambers in addition to IBA MatriXX matrix detector were compared to each other using different measurement set-ups. The ionisation ...

• Proton Direct Ionization in Sub-Micron Technologies : Numerical Method for RPP Parameter Extraction 

  Lüdeke, Sascha; Javanainen, Arto (Institute of Electrical and Electronics Engineers (IEEE), 2022)

  This work introduces a numerical method to iteratively extract parameters of a rectangular parallelepiped (RPP) sensitive volume (SV) from experimental proton direct ionization SEU data. The method combines two separate ...

• The pion single-event latch-up cross-section enhancement : mechanisms and consequences for accelerator hardness assurance 

  Coronetti, Andrea; Alia Garcia, Ruben; Cerutti, Francesco; Hajdas, Wojtek; Söderström, Daniel; Javanainen, Arto; Saigne, Frederic (Institute of Electrical and Electronics Engineers (IEEE), 2021)

  Pions make up a large part of the hadronic environment typical of accelerator mixed-fields. Characterizing device cross-sections against pions is usually disregarded in favour of tests with protons, whose single-event ...

• Current Transport Mechanism for Heavy-Ion Degraded SiC MOSFETs 

  Martinella, Corinna; Stark, R.; Ziemann, T.; Alia, R. G.; Kadi, Y.; Grossner, U.; Javanainen, Arto (Institute of Electrical and Electronics Engineers, 2019)

  High sensitivity of SiC power MOSFETs has been observed under heavy ion irradiation, leading to permanent increase of drain and gate leakage currents. Electrical postirradiation analysis confirmed the degradation of the ...

• Dosimetry study in an X-ray irradiator : Monte Carlo simulations and experimental results on radio-photoluminescence samples 

  Alem, Abrham (2023)

  Matter’s exposure to ionizing radiations leads to a variety of possible interactions. Depending on the specific interaction type, energy can be deposited into matter via different mechanisms. The quantification of the ...
