Design and development of photoelectron detection chambers for the DELPHI experiment RICH Cerenkov counters
Description
The particle identifier of the Barrel-RICH detector, based on the Cerenkov effect is a crucial element of the DELPHI spectrometer. In this detector, Cerenkov light is focussed as a ring whose diameter is related to the velocity of the particle. The measure of the ring's diameter is done by conversion of photons in a gaseous environment and then by measure of the position of the photons in a wire chamber after the drift of the photoelectrons. Three types of wire chambers (chambers in U shape, circular chambers, chambers with flat cathodes) have been designed and tested. The choice of the flat cathode chambers has been determined by the reliability, the simplicity and the considerations of price

L'identificateur de particules du detecteur Barrel-RICH, base sur l'effet Cerenkov, est un element crucial du spectrometre DELPHI. Dans ce detecteur, la lumiere Cerenkov est focalisee selon un anneau dont le diametre est lie a la vitesse de la particule. La mesure du diametre de l'anneau s'opere par conversion des photons dans un milieu gazeux puis par mesure de la position des photons dans une chambre a fils et apres derive des photoelectrons. Trois types de chambres a fils (chambres en U, chambres circulaires, chambres a cathodes planes) ont ete concues et testees. Le choix final de chambres a cathodes planes a ete determine par la fiabilite, la simplicite et les considerations de prixFiles
