The CPLEAR detector at CERN
The CPLEAR collaboration has constructed a detector at CERN for an extensive programme of CP-, T- and CPT-symmetry studies using and produced by the annihilation of 's in a hydrogen gas target. The and are identified by their companion products of the annihilation which are tracked with multiwire proportional chambers, drift chambers and streamer tubes. Particle identification is carried out with a liquid Cherenkov detector for fast separation of pions and kaons and with scintillators which allow the measurement of time of flight and energy loss. Photons are measured with a lead/gas sampling electromagnetic calorimeter. The required antiproton annihilation modes are selected by fast online processors using the tracking chamber and particle identification information. All the detectors are mounted in a 0.44 T uniform field of an axial solenoid of diameter 2 m and length 3.6 m to form a magnetic spectrometer capable of full on-line reconstruction and selection of events. The design, operating parameters and performance of the sub-detectors are described.

The CPLEAR detector at CERN
The CPLEAR collaboration has constructed a detector at CERN for an
extensive programme of CP-, T- and CPT-symmetry studies using K-0 and
<(K)over bar (0)> produced by the annihilation of <(p)over bar ‘s> in a
hydrogen gas target. The K-0 and <(K)over bar (0)> are identified by
their companion products of the annihilation K(+/-)pi(-/+) which are
tracked with multiwire proportional chambers, drift chambers and
streamer tubes. Particle identification is carried out with a liquid
Cherenkov detector for fast separation of pions and kaons and with
scintillators which allow the measurement of time of flight and energy
loss. Photons are measured with a lead/gas sampling electromagnetic
calorimeter. The required antiproton annihilation modes are selected by
fast online processors using the tracking chamber and particle
identification information. All the detectors are mounted in a 0.44 T
uniform field of an axial solenoid of diameter 2 m and length 3.6 m to
form a magnetic spectrometer capable of full on-line reconstruction and
selection of events. The design, operating parameters and performance of
the subdetectors are described
The DELPHI detector at LEP
DELPHI is a 4π detector with emphasis on particle identification, three-dimensional information, high granularity and precise vertex determination. The design criteria, the construction of the detector and the performance during the first year of operation at the large electron positron collider (LEP) at CERN are described.0info:eu-repo/semantics/publishe
