Convenors and All
21/04/2004, 10:40
We would like to list the relevant topics where work and collaboration could be enhanced by organizing informal inter-regional working groups. The discussion needs some preparation. 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...

Gollin, G. (Univ. of Illinois)
21/04/2004, 14:00
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...

In order to study whether a TPC in combination with a Micro Pattern Gas Amplification stage can meet the demands of future Linear Collider central tracking systems, a small cylindrical TPC Prototype was built in Karlsruhe and equipped with two GEMs and highly-integrated front-end electronics. The studies imply two beam tests at the Proton-Synchrotron (PS) at CERN as well as a test in a...

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...

Jan Timmermans
21/04/2004, 15:35
An '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...

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...

Michael Weber
21/04/2004, 16:25
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...

At the US LC workshop held at SLAC in January 2004, it became clear that the SLC experience with beam-related pickup could have important consequences for the vertex detector at the future LC. 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...
