[en] The paper reviews the development of particle detectors which are used to probe the nature of matter. The detectors discussed include: geiger counter, drift chamber, time projection chamber, semiconductors, silicon drift chamber and ring imaging Cerenkov counter. (U.K.)

[en] A Waveform Sampler Module (WSM) for the measurement of signal shapes coming from the multi-hit drift chambers of the SLAC SLC detector is described. The module uses a high speed, high resolution analog storage device (AMU) developed in collaboration between SLAC and Stanford University. The AMU devices together with high speed TTL clocking circuitry are packaged in a hybrid which is also suitable for mounting on the detector. The module is in CAMAC format and provides eight signal channels, each recording signal amplitude versus time in 512 cells at a sampling rate of up to 360 MHz. Data are digitized by a 12-bit ADC with a 1 μs conversion time and stored in an on-board memory accessible through CAMAC

[en] The report is concerned with the cell design and electrostatic optimisation for the ZEUS Central Tracking Detector (CTD). The CTD is being designed for charged track reconstruction and particle momentum measurement in the ZEUS experiment at the HERA electron-proton collider. The contents of the report is divided into two parts. The first part describes the techniques employed in the study, and includes: design overview, voltage optimisation, strategy evolution, electrostatic screens, and optimisation over many superlayers. The second part contains a critical assessment of the results obtained, including optimised parameters, operational stability and alternative field values. (U.K.)

[en] A review of High Energy Physics detectors based on drift chambers is presented. The ionization, drift diffusion, multiplication and detection principles are described. Most common drift media are analysied, and a classification of the detectors according to its geometry is done. Finally the standard read-out methods are displayed and the limits of the spatial resolution are discussed. (Author)

[en] A report on the status of the European Fast RICH protype is given. The design of this prototype is deduced from the Fast RICH detector originally proposed for the PSI B-factory. The construction and the assembly of the detector are finished. The readout electronics, consisting of an arrangement of fast analog and digital electronic circuits especially developed for this new type of detector, fully stands the specifications. Tests of the prototype, first with cosmic particles, followed by tests in particle beams, are scheduled for summer/fall 1992

[en] A gas mixture containing nickelocene [Ni(C₅H₅)₂] vapour can be ionized by a N₂-laser beam. This can be used for detector calibration. First tests with a drift chamber are reported. (orig.)
