V prvem delu diplomske naloge je opisan pojav disperzije ter posledice tega pojava, ki se pojavljajo v optičnih zvezah. Obstajata dve vrsti disperzije (kromatska in nekromatska), vsaka pa ima več podvrsti, tako, da je potrebna podrobna razlaga za razumevanje razlike med podvrstmi.
Sledi praktični p ...

V magistrski nalogi smo raziskovali delovanje različnih modelov poškodb biološkega tkiva, ki nastanejo zaradi izpostavljenosti visokim temperaturam. Vsi temeljijo na poznavanju temperature tkiva. Nekateri so neposredno odvisni od temperature, posredno odvisne pa smo nadgradili, da so postali neposre ...

We present experimental results obtained with the LAPPD Gen-II large-size MCP-PMT. Using a custom-designed PCB capacitively coupled to the anode backplane with different segmentation patterns, the photo-detector is read out using the PETsys TOFPET2 and FastIC ASICs. The results reported in this pape ...

Single photon sensitive detectors used in high energy physics are, in some applica-tions, required to cover areas the size of several m2, and more specifically in very strong demand with an ever finer imaging and timing capability for Cherenkov Ring Imaging Detector (RICH) configurations. We are eva ...

We present a comprehensive characterization of the LAPPD Gen-II, a large-area microchannel-plate photomultiplier tube (MCP-PMT) equipped with a capacitively coupled sensing (readout) electrode. Two detector variants with different geometries and materials were investigated using a picosecond pulsed ...

As a part of the LHCb RICH Future upgrades experimental program, we studied hydrophobic aerogel tiles from Chiba University during the 2021 CERN SPS testbeam. In a 180 GeV/c proton beam, we tested aerogels with different refractive indices and different thicknesses. The Cherenkov light radiated from ...

We recently measured the branching fraction of the $B^+ \to K^+\nu\bar{\nu}$ decay using 362 fb$^{-1}$ of on-resonance $e^+e^-$ collision data under the assumption of Standard Model kinematics, providing the first evidence for this decay. To facilitate future reinterpretations and maximize the sci ...

We search for the rare decay 𝐵+ →𝐾+𝜈 ¯ 𝜈 in a 362 fb−1 sample of electron-positron collisions at the ϒ(4𝑆) resonance collected with the Belle II detector at the SuperKEKB collider. We use the inclusive properties of the accompanying 𝐵 meson in ϒ(4𝑆)→𝐵 ¯ 𝐵 events to suppress backgrou ...

We present a study of the rare charm meson decays $D^0 \to K^+K^-e^+e^-, \pi^+\pi^-e^+e^-$, and $K^-\pi^+e^+e^-$ using a 942 fb$^{-1}$ dataset collected by the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We identify $D^0$ candidates via the charge of the pion from $D^{\ast +} \to ...
