The Time Expansion Chamber as High Precision Drift Chamber
With the principle of the time expansion chamber and the additional measurement of the position of the avalanche along the circumference of the anode wire it is possible to reconstruct the spatial distribution of the primary ionization in space. A position resolution for minimum ionizing tracks of a 5 30 urn is expected. First tests and concepts for vertex detectors are presented.
متن کاملReadout Electronics for the ALICE Time Projection Chamber
In this paper we present the architecture of the Readout Electronics for the Time Projection Chamber (TPC) of the ALICE experiment at CERN LHC. The ALICE TPC electronics consists of 557568 channels. A single readout channel is made of two basic units: (a) an analogue ASIC (PASA) that incorporates the shaping/amplifier circuits for 16 channels; (b) a mixed-signal ASIC (ALTRO) that integrates 16 ...
متن کاملtight frame approximation for multi-frames and super-frames
در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...
15 صفحه اولThe BaBar Drift Chamber
The central drift chamber for the BaBar detector at the PEP-II Bfactory at SLAC is a cylindrical chamber with a length of 280 cm and outer radius of 81 cm. It consists of 40 layers of small hexagonal cells arranged in 10 axial and stereo super-layers. In order to minimize multiple scattering, light materials are used for the mechanical structure, and the gas mixture is Helium based. The pulse-h...
متن کاملNew Drift Chamber for - the Mark Ii
A new cylindrical drift chamber is being constructed for the Mark lI detector for use at the new SLAC Linear Collider. The design of the new chamber is based on a multi-sensewire cell of the jet-chamber type. In addition to driitime measure men@ pulse height measurements from the sense wires will provide electron-hadron separation by dE/dz. The design and construction of the chamber, tests of p...
