Software data acquisition system for the ''Chateau de Cristal'' multicounter 74 BaF2

Creators

Description

The ''Chateau de Cristal'' is a 74 BaF2 detector assembly. Other detectors such as Ge (up to 12) and particle detectors can be added to this multidetector. The data acquisition system hardware and software are implemented in 3 VME crates. The operating system is handled by 68000 Motorola microprocessors. This work is dedicated to the initialization and control tasks of the multidetector. Handling of high voltage power supply for the 74 BaF2 detectors via a RS 232 C serial port, CAMAC initialization for the ADC 4300 Lecroy and DFC modules, data exchange between the 3 VME crates and automatic energy calibration for the BaF2 detectors. All the software is written in 68000 Motorola assembly language

Abstract (French)

Le Chateau de Cristal est constitue de 74 detecteurs BaF2 auxquels seront adjoints 12 detecteurs Ge et des detecteurs additionnels. Le logiciel de gestion de donnees de ce systeme est implante dans 3 chassis VME pilotes par des processeurs 68000. Ce travail, plus specialement consacre aux taches d'initialisation et de controle de l'acquisition, concerne: la gestion des hautes tensions d'alimentation des 74 photomultiplicateurs des BaF2 pilotees par une ligne serie RS 232 C, l'initialisation des modules CAMAC (DFC et ADC Lecroy 4300), l'intercommunication entre les 3 chassis VME tant pour les messages que pour les donnees et la sequence automatique de calibrage en energie des BaF2. Tous les logiciels sont implantes en language assembleur
