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 …

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 …

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 …

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 …

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 …

Pixellated radiation detectors for scientific applications
… in the vertex detector for the International Linear Collider. The noise of the sensor was measured to be 35±5 e, which agrees well with simulated data. The dark current was found to be 175 pA/cm2. The SNR performance for minimum ionising particles detection was demonstrated to be 40. The …

Electron Beam Diagnostic at the ELBE Free Electron Laser
… developed at DESY in the framework of the TESLA linear collider project and the X-ray free electron laser (FEL) project. The ELBE linac is designed to operate with an accelerating field gradient of 10 MV/m so that the maximum design electron beam energy at the exit of the second module is 40 MeV. …
