Contribution to electronics by microprocessors of an experiment realized on a very high energy accelerator

Description

We describe a fast triggering system (100 ns) which, from a wire chamber and from a hodoscope of scintillators, enables one to select events satisfying certain conditions of multiplicity and momentum threshold. By using the method of a ''mask'', which makes the comparison between the real events and an adjustable reference matrix possible, the kept events are those which correspond to the foreseen topology.

Abstract (French)

L'experience etudie la physique hadronique a tres haute energie via des collisions proton-proton, proton-antiproton et ion leger-ion leger. Ce memoire decrit la contribution a toute la chaine electronique, des detecteurs a l'ordinateur en ligne. Il decrit les principales realisations, dont la selection rapide des particules emises dans une direction transverse par rapport aux faisceaux avec une impulsion superieure a une valeur seuil ajustable et satisfaisant a des contraintes de multiplicite minimale et maximale egalement ajustables. La methode de declenchement utilise la technique du masque ou des matrices de reference definissent la topologie des bons evenements dans l'espace des impulsions. Un microprocesseur commande les operations de chargement de la bonne matrice, associee a un seuil donne, a partir des memoires mortes dans des memoires vives. Nous decrivons aussi tous les systemes de tests de l'electronique et des detecteurs dont celui du declenchement sur l'impulsion, assiste lui aussi par microprocesseur
