The TESLA Time Projection Chamber
نویسنده
چکیده
TESLA (TeV-Energy Superconducting Linear Accelerator) is an ee linear Collider designed to operate in the energy range beyond the mass of the Z and up to the TeV region. If approved, TESLA would allow a wide physics program, focusing among other things on precision tests of the established Standard Model, the Higgs mechanisms and the discovery of new particles. To optimally exploit the physics potential of TESLA, the detector has to satisfy some stringent requirements. It has to have a very good track momentum resolution to measure the Z recoil mass, an excellent vertex resolution for heavy flavour identification, a high resolution in the reconstruction of electromagnetic and hadronic showers in the calorimeter, and has to be as hermetic as possible. The general concept of a detector fulfilling these criteria, discussed within the ECFA-DESY study, is described in details in [1,2]. In this contribution, we describe the current design of the Time Projection Chamber (TPC) and the different ongoing studies concerning the readout technologies.

R&d on the Gem Readout of the Tesla Tpc
Studies for the TESLA TPC (Time Projection Chamber) with GEM (Gas Electron Multiplier) readout at DESY/Hamburg University are presented. Two test chamber setups are being operated. The studies include basic GEM performance, tracking and the determination of the resolution using different pad sizes and geometries. Our measurements show that chevron shaped pads lead to a better point resolution c...
متن کاملA TESLA-based mutual authentication protocol for GSM networks
The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...

The experimental goal of the MuCap experiment at the Paul Scherrer Institute (PSI) is a high-precision measurement of the singlet capture rate of the nuclear muon capture on the free proton in the reaction m þp-nþnm. The measuring principle is a lifetime measurement whereas the experimental approach is based on a specially developed Time Projection Chamber (TPC) operating with ultra-pure and de...

A micro time-projection-chamber (micro-TPC) with a detection volume of 23×28×31 cm was developed, and its fundamental performance was examined. The micro-TPC consists of a micro pixel chamber with a detection area of 31×31 cm as a two-dimensional imaging device and a gas electron multiplier with an effective area of 23×28 cm as a pre-gas-multiplier. The micro-TPC was operated at a gas gain of 5...
