H1

H1 is a particle detector in operation at HERA in DESY, Hamburg. It began operating together with HERA in 1992. Leptons are collided with protons by HERA in the interaction point of H1. H1 is operated by an international collaboration of about 400 physicists from 42 institutes in 15 countries. The detector is about 12 x 15 x 10 meters big and weighs 2800 tons. It is accompanied by an electronics trailer three stories high. While H1 is a general purpose detector its main design feature is an asymmetric construction to cope with the boosted center of mass in the laboratory frame due to the large energy imbalance of the colliding beams. In the forward direction the instrumentation has higher granularity to give a better resolution for refined measurement of the proton remnant left after the collision with the incident lepton. The reaction products, often including the proton remnant and the scattered lepton, are detected by several subdetectors. Combination of their information allows the identification of particles from the reaction, or a least the reconstruction of the overall reaction kinematics. This in turn allows the classification of the reaction. From the center outwards, H1's most important systems are:
