AbstractAbstract
[en] It is difficult to imagine the realization of a system with a microprocessor without the use of an adapted development system. As these systems are prohibitively expensive, it is difficult for a laboratory to acquire them. A computer, such as the Multi 20 is provided with programme generating tools and supervisors to put the computer's ressources at the microprocessor's disposal. An electronic crate assures interface functions with the computer, the emulation of the microprocessor and the loading of EROM and the live memory lank in order to execute the different units integrated into the crate, enables the crate to be used as a portable repair and maintenance outfit for the materials installed. In the first part of the text, we present the principles of the development tools showing how they are used to realize microprocessor equipment. In the second part, the software is optimized together with the choice of materials in order to define a low cost development system

On peut difficilement concevoir une realisation incluant un microprocesseur, sans utiliser un systeme de developpement adapte. Le prix de ces systemes est tel qu'il peut etre difficile, pour un laboratoire, d'en faire l'investissement. Un ordinateur tel que le Multi 20 est muni des outils de generation de programme, et de superviseurs pour mettre l'ensemble des ressources de l'ordinateur au service du microprocesseur. Un chassis electronique assure les fonctions d'interface avec l'ordinateur, d'emulation du microprocesseur, de chargement d'EROM et de banc memoire vive pour executer les programmes a la vitesse du microprocesseur. Un tiroir console, integre au chassis, permet d'utiliser celui-ci comme valise de depannage et de maintenance de materiels installes. Dans une premiere partie, nous presentons le principe des outils de developpement et nous les utilisons pour realiser un appareil a microprocesseur. Dans une seconde partie, nous perfectionnons logiciel et materiel pour arriver a un systeme de developpement a bas prix de revientOriginal Title

AbstractAbstract
[en] The project reported deals with one of the aspects of power plant control and management. In order to perform optimal distribution of power and load switching, one has to solve a specific optimization problem. In order to solve this problem one needs to collect current and power expenditure data from a large number of channels and have them processed. This particular procedure is defined as data acquisition and it constitutes the main topic of this project. A microprocessor-based data acquisition system for power management is investigated and developed. The current and power data of about 100 analog channels are sampled and collected in real-time. These data are subsequently processed to calculate the power factor (cos phi) for each channel and the maximum demand. The data is processed by an AMD 9511 Arithmetic Processing Unit and the whole system is controlled by an Intel 8080A CPU. All this information is then transfered to a universal computer through a synchronized communication channel. The optimization computations would be performed by the high level computer. Different ways of performing the search of data over a large number of channels have been investigated. A particular solution to overcome the gain and offset drift of the A/D converter, using software, has been proposed. The 8080A supervises the collection and routing of data in real time, while the 9511 performs calculation, using these data. (Author)

AbstractAbstract
[en] An experimental facility has been developed to monitor the entry rate and concentration of 222Rn in two basement type structures surrounded by soil having a permeability on the order of 1--12 m2. A data acquisition system recorded environmental conditions outside and inside the structures, including basement air exchange rates, every 15 min. Indoor 222Rn concentrations ranged from 400 to 1400 Bq m-3. The observed 222Rn entry rate is highly variable and has two primary components; a constant input rate caused by diffusion of 222Rn through the concrete walls and floor, and a variable rate that depends upon indoor-soil pressure differentials of only a few pascals. Pressure differentials are dependent upon wind speed and wind direction. Stack effect was not significant. During a two week period, with relatively calm winds, diffusion through the concrete walls and floor plus the floor-wall joint accounted for more than 80% of the total 222Rn entry

AbstractAbstract
[en] This report constitutes an attempt to study systematically the properties of the detection head of a multichannel collimating grid camera. The object has been to show the disadvantages of present equipment, and to propose possible solutions for overcoming them: firstly by improving the methods used for collecting data, and the performances of the equipment doing the collecting; secondly by devising methods for processing the data so as to reduce image distortion and, first of all, the astigmatism due to the collimator. The first part deals with the study of the formation of the image by means of the collimating grid, the second with the examination of many systems which could be used for acquiring data. The last part summarizes the experiments carried out and proposes an experimental programme for the development of a prototype. (author)

AbstractAbstract
[en] The purpose of this study, which falls within the purview of a nuclear physics research laboratory, is the development of a simple to use conversational text editor to mitigate the defects of the MMT2 monitor. The operations to be executed are: - creation of a source file written in FORTRAN - concatenation of the various stages to obtain a workable program: FORTRAN compilation, edition of links, group generation; - execution of this program. These operations are performed in two different ways: 1) by using the system controls as from the teleprinter (this corresponds to the previous use). The sequence of controls to be effected is described; 2) by using the EDI 125 conversational editor

Cette etude qui se situe dans le cadre d'un laboratoire de recherche en physique nucleaire a pour but la realisation d'un editeur de texte conversationnel simple a utiliser, palliant les defauts du moniteur MMT2. Les operations a effectuer sont les suivantes: - creation d'un fichier source ecrit en FORTRAN; - enchainement des differentes etapes permettant d'obtenir un programme executable: compilation FORTRAN, edition de liens, generation de groupe; - execution de ce programme. Ces operations sont realisees de deux facons differentes: - en utilisant les commandes systeme a partir de la teletype (ceci correspond a l'utilisation anterieure). La sequence des commandes a effectuer est decrite; - en utilisant l'editeur conversationnel EDI 125Original Title

AbstractAbstract
[en] The acquisition and supervision system of SARA's (Systeme Accelerateur Rhone-Alpes) parameters is built up. The basic hardware consists of: - A PDP 11/10 computer with a 64 K bytes memory capacity. The system and load device is a floppy disk of 28 megabytes capacity. - A CAMAC crate including a data logger with 224 input channels, a terminal driver (JTY21) and three modules designed for reading out a few digital data, for instance polarities of power supplies. The software provides three distinct programs: AKITS, which uses 3 commands, detects and signals functioning defects in the CAMAC modules used. AKIDO which uses 11 commands, is the acquisition and organization program of the accelerator's functioning parameters. AKISUR is the supervision program of the functioning parameter's stability, within a fixed gap, during the accelerator running

AbstractAbstract
[en] The Specialized Automation of Image Processing (A.S.T.I.) introduces a new stage between digitalization and image software processing; it is a preprocessing allowing the transmission to a mini-computer of only significant information on the images. The system includes a television camera, a memory and a television monitor projecting the stored image. Hardware circuits very rapidly perform the image processing. The information can then be transmitted to a mini computer. The whole is controlled either from a console or automatically by the mini-computer

L'Automate Specialise de Traitement d'Images (A.S.T.I.) introduit une etape nouvelle entre la numerisation et le traitement logiciel des images: il s'agit d'un pretraitement permettant de ne transmettre a un minicalculateur que les informations significatives des images. L'appareil comprend une camera de television, une memoire de stockage et un moniteur de television visualisant l'image stockee. Une logique cablee realise a grande vitesse le traitement de l'image. Les informations obtenues peuvent etre transmises a un minicalculateur. L'ensemble est pilote, soit par une console, soit automatiquement par le minicalculateurOriginal Title

AbstractAbstract
[en] In an experimental set up, the main function of the ''CALI system'' is to achieve ''coincidence'' between logic channels. This system also provides a fast selection of the events and their identification by a digital word, and the connection to the data acquisition system
[fr]
Le systeme CALI a pour fonction principale de realiser des ''coincidences'' entre des signaux logiques issus des detecteurs d'une experience de physique nucleaire. Il permet egalement une selection rapide des evenements, leur identification par un code associe et la ''conversation'' de l'experience avec le systeme d'acquisition de donnees. Ce systeme est compose de 6 modules disponibles en standard NIM (famille CALI 5) ou CAMAC (famille CALI 6). Le traitement des ''coincidences rapides'' se fait par la liaison en bus de modules d'entree (CALI R entrees: 16 voies, et CALI R Extension Entrees: 32 voies) et de modules de decision (CALI R Decisions: 16 voies, et CALI R Multiplicite: 32 voies). Les modules CALI L (16 voies) assurent le traitement des ''coincidences lentes''. Les fonctions du systeme CALI peuvent etre completees par celles de modules ECL line developpes par la Societe Le Croy. Quelques applications du systeme CALI sont executees dans des experiences multidetecteurs (de 16 a 128 voies en coincidence rapide)Original Title
