CMOS Charge amplifier for liquid argon Time Projection Chamber detectors
1. INTRODUCTION We developed an integrated circuit (IC) for the readout of LAr (Liquid Argon) TPC (Time Projection Chamber) neutrino detectors. These detectors employ LAr simultaneously as massive target and detection medium. The detection of secondary particles produced in neutrino interactions is achieved by collecting, on a system of wires at the sides of the detector, the electric charges f...
متن کاملThe TESLA Time Projection Chamber
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 ...
متن کاملAn Analysis of Gas Flow in the BaBar Drift Chamber
An analysis based on the Green’s function for the diffusion equation indicates that the BaBar drift chamber could be purged of air down to 1 ppm in 8 hours with a purge gas velocity in the chamber of 0.043 cm/s, corresponding to one volume change every 2 hours. Anecdotal evidence from CLEO and ALEPH supports this claim. • It is proposed that the gas be fed into the chamber through 64 holes of 1...
متن کاملA Drift{diffusion Equation for Charge Transport in Inhomogeneous Materials
From a hopping rate equation for disordered materials we derive a macroscopic drift{di usion equation. For this purposes two space{time scales are simultaneously considered. The microscopic dynamics is characterized by the distribution of localized states and the hopping rate. On the macroscopic space scale both the hopping rate and the disordered material are allowed to be inhomogeneous.
متن کاملThe 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.
