Calorimetry at a Future Linear Collider
… the optimisation of the calorimeter design for collider experiments at the future Compact LInear Collider (CLIC) and the International Linear Collider (ILC). The detector design of these experiments is built around high-granularity Particle Flow Calorimetry that, in contrast to traditional …

MAPS calorimetry for a future linear collider
The International Linear Collider (ILC) is intended to be a new high precision electron-positron collider operating at the TeV scale. The studies detailed within this thesis deal primarily with the development of Monolithic Active Pixel Sensors (MAPS) which could be used as the sensitive component …

Detectors and Physics at a Future Linear Collider
An electron-positron linear collider is an option for future large particle accelerator projects. Such a collider would focus on precision tests of the Higgs boson properties. This thesis describes three studies related to the optimisation of highly granular calorimeters and one study on the …

Electro-Optic Diagnostic Techniques For The CLIC Linear Collider
… three of the probe laser background term, the linear term to Coulomb field and the quadratic term to Coulomb field. Three methods are induced based on this frequency analysis result to retrieve Coulomb field value which is emitted from electron beam. The measured 1.3 MV/m field strength agrees …

Simulation studies for a high resolution time projection chamber at the international linear collider
The International Linear Collider (ILC) is planned to be the next large accelerator. The ILC will be able to perform high precision measurements only possible at the clean environment of electron positron collisions. In order to reach this high accuracy, the requirements for the detector …

Novel designs for undulator based positron sources
Proposed high energy electron-positron linear colliders require a high ux of positrons. To achieve this a number of new positron source designs have been proposed. One of these is an undulator-based positron source, which is the baseline positron source design for the International Linear Collider. …

Studies in positron and gamma ray production for future facilities
The next generation of particle colliders after the LHC (Large Hadron Collider) at CERN are likely to be high-precision electron positron colliders such as the ILC (International Linear Collider) or CLIC (Compact Linear Collider). This next generation of colliders will give new scope to explore …

Ion backdrift minimisation in a GEM-based TPC readout
… reached a consensus that the next large particle collider which will be built after the LHC (Large Hadron Collider) will be the electron-positron linear collider ILC (International Linear Collider). It will allow accelerating electrons and positrons to energies of up to 1 TeV without the great …

Higgs production via weak boson fusion in the Standard Model and the MSSM
… important process at both the LHC and a future linear collider. Not only is it a possible Higgs discovery channel, but it also allows us to study the properties of the Higgs boson and the mechanism of electroweak symmetry breaking. In this thesis this process is studied in detail for both the …

Heavy quarks in effective field theories
… jets induced by tt pair production at a future linear collider. Formal applications include: a definition of top mass relevant for measurements that use top induced jets, a new renormalization group equation in an infrared scale intrinsic to heavy quark masses and its generalization for QCD …

Beam position monitoring at CLIC
… in Geneva, Switzerland the design of the Compact LInear Collider (CLIC) for high energy physics is studied. To achieve the envisaged high luminosity the quadrupole magnets and radio-frequency accelerating structures have to be actively aligned with micron precision and submicron resolution. This …

High power X-band RF test stand development and high power testing of the CLIC crab cavity
… structures at CERN, as re-quired for the e+ e- collider research programme CLIC (Compact Linear Collider). Signif-icant improvements to the control system and operation of the first test stand, Xbox-1 are implemented. The development of the second X-band test stand at CERN, Xbox-2 is followed …

Third-order QCD corrections to heavy quark pair production near threshold
… is an important task at the future International Linear Collider. The most promising process is the top quark pair production in the threshold region. In this region the top quarks behave non-relativistically and a perturbative treatment using effective field theories is possible. Current second …

High power high efficiency multiple-beam klystron design
… Beam Klystron (MBK) for use in the Compact Linear Collider (CLIC). In this regard refinements have been made both to the MBK design, and investigation and optimisation methods used. The high desired efficiency of 80% requires low perveance beams, to achieve the specification output power 20 …

Resolution studies of a GEM-based TPC
The next large collider to be build after the Large Hadron Collider LHC is the electron-positron International Linear Collider ILC. Both collider concepts complement each other. The LHC, reaching centre of mass energies of up to 14 TeV, has a high discovery potential, while the ILC with its well …
