Abstract

Abstract: The new tracking system of the Spherical Neutral Detector for experiments at the VEPP-2000 collider in Novosibirsk is described. The system consists of a 9-layer drift chamber with 24 jet cells and a proportional chamber in a common gas volume. Main system features are its small size and high density of readout channels for gaseous tracking systems at colliding experiments. The drift chamber provides at least four measurements along the track for charged particles within 94% solid angle and nine measurements for particles propagating at large angle relative to the beam axis. coordinates (in a plane perpendicular to the beam axis) are obtained using the ionization drift time measurement. Longitudial coordinates are measured using charge division on anode wires and charge distribution on cathode strips. Design angular resolutions for radial tracks are , , the vertex resolution is . The full-size prototype of the tracking system has been assembled and tested. The wire structure of the prototype represents one quadrant of the chamber. Results of the prototype assembly quality control and tests with radioactive sources and cosmic rays are presented. They are in a good agreement with expected system parameters.

Abstract

Abstract: Tracking system of the SND detector is fully assembled, equipped and tested with cosmic muons in 2007. During these tests operation conditions of the system were checked and optimized and main parameters of the system were measured. Design values of gas gain, detection efficiency and space resolution were achieved. Tracking system is ready for installation into the SND detector and coming data taking at the VEPP-2000 -collider in Novosibirsk. [Copyright &y& Elsevier]

Abstract

Spherical Neutral Detector (SND) is a general purpose non-magnetic detector for experiments at VEPP-2000 collider in Novosibirsk in the energy range . Charged particle track coordinates are measured using drift and proportional chambers placed in a common gas volume. Particle identification is performed using energy deposition in the drift chamber at low particle momenta and aerogel threshold counters at high particle momenta . Photon energies are measured using 3-layer spherical electromagnetic calorimeter. Muons penetrating the detector and cosmic background muons are detected by the muon system based on proportional tubes and plastic scintillator counters. At present the detector is operating at VEPP-2000. [ABSTRACT FROM AUTHOR]
