Dr Yoshihisa Iwashita (Kyoto University)21/04/2004, 15:00A 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...Go to contribution page

The large-area TPC prototype (1024 channels, 50 cm drift and 50 cm diameter) has been in operation since July 2003 at Saclay. Results from data taken in November 2003 for both Ar-Isobutane and Ar-CF4 mixtures at various magnetic field settings will be shown.Go to contribution page

Jan Timmermans21/04/2004, 15:35An 'ideal' readout scheme of a TPC would consist of gas multiplication by either one or more GEM or Micromegas foils, followed by a charge collection device with a granularity corresponding to the primary ionisation cluster spread (and assuming sufficiently low diffusion). A readout channel with granularity similar to the 'grid' size in GEM and Micromegas foils has been realised, as a first...Go to contribution page

Kirsten Sachs21/04/2004, 15:50If 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...Go to contribution page

Michael Weber21/04/2004, 16:25A 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...Go to contribution page

Alexander Vasiljev21/04/2004, 16:40The 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...Go to contribution page

It also allows better understanding of the impact of vertex detector parameters on...Go to contribution page

There are major differences for the warm and cold machine, and for different detector technologies. We review the current thinking in the light of these discussions, and consider pointers to...Go to contribution page

The purpose of these studies is to determine if this detector, combined with a fully 3D (CCD) inner tracker, is sufficient for the reconstruction of tracks in the dense core of jets. Using standard algorithms, track finding efficiencies are presented for...Go to contribution page
