The aim of this project was to calculate the surface resistance of different materials and coatings as well as to design a multi-crystal multi-mode dielectric resonator. CST was used to design the dielectric resonator that can be used with four different dielectrics and to measure at seven different resonance frequencies. Additionally, the surface ...
We present discharge probability studies performed with a single Thick Gas Electron Multiplier (THGEM) irradiated with alpha particles in Ar-CO$_2$ and Ne-CO$_2$ mixtures. We observe a clear dependency of the discharge stability on the noble gas and quencher content pointing to lighter gases to be more stable against the development of streamer dis...
A relativistic proton bunch generates a magnetic field that can apply a focusing force to itself when exposed to plasma, which is known as adiabatic focusing. We perform experiments at CERN’s proton-driven plasma wakefield accelerator (AWAKE) to observe the adiabatic focusing response of low density plasma to a relativistic proton bunch. We studied...
This report will discuss the characterization of the silicon bulk material in terms of its electrical properties and the charge collection using a radioactive source. This project is part of research carried out for the new High Granularity Calorimeter at the CMS experiment. The main properties studied in this characterization project are the deple...
We use the newly proposed Energy Mover’s Distance as a measure of jet isotropy to define new jet substructure observables for quark/gluon discrimination and identifying hadronically-decaying top quarks with large transverse momentum. We assess their effectiveness by comparing them with other classifiers. The quark/gluon study is conducted at hadron...
This work focuses on a crystal channeling simulation using the existing bent crystal example in GEANT4. The goal of the study was to install and learn how to use the crystal channeling routine by reproducing basic validation plots. This routine will be used to study the feasibility of a proposed proof-of-principle two-crystal experiment at the LHC ...
This document describes several optimization problems that were solved for the development of a monitoring blimp for the FCC-hh detector as well as tests performed on the PhaseSpace motion capture system. The definition and computation of the optimization problems' objective functions is detailed; the motivation behind the choice of the GDOP functi...
The high collision rates of the High-Luminosity Large Hadron Collider (HL-LHC) will require an upgrade for its experiments to perform adequately. The ATLAS experiment's current detector will be replaced with a new Inner Tracker (ITk), with installation starting in 2026. Components that will come together to become the ITk are currently being built ...
The following presented work is framed within a hidden valley dark matter model. This model includes a massive Z’ mediator boson, coupling the SM sector to the DM sector via the above s-channel process. Additionally the dark quarks (DQ) are able to hadronise and form semi-visible jets (SVJ) composed of both stable and unstable dark hadrons.
This document talks about the background of the section where the applications were developed, the original problem that prompted the need for the applications, a description of what the apps need to do, a summary of the developed features and possible future expansions of the applications.
