The D0 detector (often written as DØ to make it clear that it is the number zero, not the letter O ) is one of two large detectors at the Tevatron particle accelerator, which at the Fermi National Accelerator Laboratory ( Fermilab ) is operated been. The detector examined the substances resulting from the collision of protons and antiprotons products, ie hadrons, leptons and photons.
Inside the detector, there is a trace detection system, consisting of a silicon tracker and a Toroidmagneten for pulse determination. The second layer forms a calorimeter with liquid argon and uranium as absorber material. The outermost layer consists of a system of drift chambers for detecting muons. With the help of a magnet system, a magnetic field of 2 Tesla is generated for pulse strength determination. The detector is complemented by a Luminositätssystem for determining the collision rate and a proton detector in the forward direction (Forward Detector proton ) to study elastic collisions.
Two operating phases were distinguished: Run I from 1994 to 1996 and Run II of 2001 to the shutdown of the Tevatron September 30, 2011, together with the CDF Collaboration, based at the same laboratory, in 1995 the top quark was discovered..
Spokesman from 1983 to 1993 was Paul Grannis.
