    The process e+ e- -> 3 jets offers the opportunity to measure the strong coupling constant. For an accurate determination, precise theoretical calculations are necessary. I will give an overview on the status of the next-to-next-to-leading order calculations.

    More than 20 European laboratories have joined forces on a Design Study for the Linear Collider in the TeV range. In a bid submitted to the European Union the consortium tries to gain support to address some of the remaining high ranking issues identified in the report of the TRC. It is expected that these studies will be complemented by similar activies in Asia and in the Americas. The talk...

    One charge to the US LC Technology Options Study was to evaluate the projected availability of the warm and cold LC designs and indicate the effort required to meet specified goals. A Monte Carlo simulation was developed which estimated availability based on device counts, frequency of failure (MTTF) and time to repair (MTTR). The simulation included device accessibility, tunnel access and...

    As part of the US LC Technology Options Study, a risk analysis was performed to identify aspects of the warm and cold designs where there was significant risk that the LC might fail to achieve its energy, luminosity or availability goals. The study identified 42 items and assigned each of these a rank for likelihood, severity, time of discovery and impact. This pointed to which sub-systems of...

It is a great and important step to realize the LC project. We have built the GLCTA at KEK and just started a high-power test of an X-band accelerating structure. In the near future,we will accelerate an ultra low-emittance beam from the ATF. It...

The IPT takes raw data from the pixel sensors, and applies real-time data reduction in two steps by means of hardware: cluster collection on a local level and track reconstruction on a global level. Only the track features are stored on disk. We also discuss our...

Among the topics are for instance issues to do with having 2 IRs with comparable luminosity and energy, one of which with a crossing-angle large enough to make possible the option of a future gg-collider upgrade

    The (e+e- -> t tbar H) process has been extensively studied to determine the accuracy on the top-Higgs Yukawa coupling achievable with the TESLA collider at 800 GeV, for Higgs masses ranging from 120 GeV/c2 to 200 GeV/c2. The analysis of (H -> b bbar) and (H -> WW) channels has already shown that an accuracy on the top-Higgs Yukawa coupling better than about 10 % was achievable for most of...

    Recent developments in the treatment of a system of heavy quarks close to their production threshold are discussed. Particular emphasis is put on the next-to-next-to-next-to-leading order corrections to the energy levels and the wave function and their effect on the cross section sigma(e+e- -> t tbar). Furthermore, the resummation of logarithmic corrections within the framework of potential...

    The large size of TESLA's damping rings is dictated by the performance of the kicker, which must eject every nth bunch while leaving adjacent bunches undisturbed. The speed with which the kicker fields can stabilize, then turn off, determines the minimum space between damping ring bunches, and therefore the minimum cirumference of the damping ring. Novel schemes which might permit a...

    One possible option for the main tracking device of a detector at a future Linear Collider is a large Time Projection Chamber (TPC). To replace the traditional wire based gas amplification system of a TPC, so called Micro Pattern Gas Detectors (MPGDs) are considered a good choice. One example of such a MPGD is the Gas Electron Multiplier (GEM). At DESY a prototype TPC equipped with GEMs has...

    A super strong magnet, which utilizes permanent magnet material and saturated iron, is considered as a candidate for the final focus quadrupole in a linear collider beamline. This modified Halbach magnet configuration can have a higher magnetic field gradient than a normal permanent magnet quadrupole (PMQ) or electromagnet. There are some issues to be solved if a PMQ is to be used as a final...

    If a TPC will be used as central detector at a high energy linear collider the spatial resolution must be improved. Charge amplification with micro pattern gas detectors (MPGD), such as GEMs and Micromegas, will eliminate large systematic effects inherent in the conventional proportional wire cathode pad readout TPC. However, the transverse confinement of the spatial charge in a magnetic field...

    A critical factor in the design of a TPC for a Linear Collider is the amount of ions drifting back into the sensitive volume. To reduce this ion feedback, multi-GEM-structures are used, which further improve the intrinsic ion feedback suppression of single GEM foils. To optimize the operational parameters of such a structure extensive simulations have been performed. The simulations have been...

    The unique advantage of He-based mixtures is that the ion mobilities in He are almost by an order of magnitude higher than that in Ar. Accordingly, using the He-based mixtures could help to solve the problem of ion accumulation in the TPC volume. On the other hand, the unique advantage of GEMs is that they can operate at high gains in pure noble gases, in particular in He and its mixtures with...
