      abstract     = {The ILC is a planned linear collider, designed to provide
                      polarized electrons and positronsat energies higher than 250
                      GeV, possibly up to 1TeV, never before reached at a
                      leptoncollider. At the interaction point there will be two
                      detectors, which will perform highprecision measurement at
                      those energies. To achieve those performances, many of
                      thecomponents have to be developed beyond the current state
                      of the art. Moreover a preliminarysimulation and analysis
                      work is required to understand what type of measurementswill
                      those experiments be able to perform and which precision can
                      they achieve.In this thesis we will be mostly concerned with
                      the ILD experiment, which features alarge volume TPC used as
                      its main tracker. The first part of this thesis focusses on
                      thedesign, development and test of the first prototype of a
                      new GEM-based readout module forthat TPC, built around an
                      innovative ceramic support system which will allow a
                      reductionof the dead space in the sensitive area of a factor
                      of 3, as compared to traditional solutions.In the second
                      part of this work we will focus on the development of a
                      computationaltechnique to measure the position of edge-like
                      kinematic end-points in physical distributions.Therefore
                      this work will focus in particular on the characterisation
                      of the algorithmto define a procedure to reliably evaluate
                      the statistical and systematic errors associatedwith the
                      measurement. At the ILD such a technique would be
                      particularly useful to measurethe end-point in the kinematic
                      distributions of the decay products of new physicalstates
                      like those hypothesized by Supersymmetry. To evaluate the
                      performance of thealgorithm and of the experiment in that
                      scenario we applied that new technique to theprocess e−e+
                      ! ˜eR¯˜eR ! e±e ˜01˜01and measured the position of the
                      kinematic edge inthe momentum distribution of the final
                      state leptons obtaining a factor of 2 improvementon the
                      accuracy in the measurement of the masses of the s-electron
                      and Neutralino, ascompared to the currently published
                      estimates.iii},
