AbstractAbstract
[en] This paper describes the methodology used for the irradiation of the integrated components and the measurements of their parameters, using Quality Insurance of dosimetry: - Measurement of the integrated dose using the competences of the Laboratoire Central des Industries Electriques (LCIE): - Measurement of irradiation dose versus source/component distance, using a calibrated equipment. - Use of ALANINE dosimeters, placed on the support of the irradiated components. - Assembly and polarization of components during the irradiations. Selection of the irradiator. - Measurement of the irradiated components's parameters, using the competences of the societies: - GenRad: GR130 tests equipement placed in the DEIN/SIR-CEN SACLAY. - Laboratoire Central des Industries Electriques (LCIE): GR125 tests equipment and this associated programmes test

AbstractAbstract
[en] We present here the prototype of a numerical counting ratemeter which is a special version of variable time-constant frequency meter (1). The originality of this work lies in the fact that the change in the time constant is carried out automatically. Since the criterion for this change is the accuracy in the annunciated result, the integration time is varied as a function of the frequency. For the prototype described in this report, the time constant varies from 1 sec to 1 millisec. for frequencies in the range 10 Hz to 10 MHz. This prototype is built entirely of MECL-type integrated circuits from Motorola and is thus contained in two relatively small boxes. (authors)

Nous presentons ici le prototype d'un ictometre numerique, celui-ci etant une version speciale d'un frequencemetre a constante de temps variable (1). Le nouvel interet de cette etude est le fait que le changement de la constante de temps se fait automatiquement. Le critere de ce changement etant la precision du resultat a afficher on change alors le temps d'integration en fonction de la frequence. Pour le prototype decrit dans ce rapport la constante de temps varie entre 1 s et 1 ms pour des frequences allant de 10 Hz a 10 MHz. Ce prototype est entierement realise en circuit integre type MECL de Motorola et se presente en consequence dans deux boitiers d'une taille relativement petite. (auteurs)Original Title

AbstractAbstract
[en] The point of interest of this frequency meter is that its accuracy is fixed in advance for the whole frequency range which is to be measured. For this, it is possible for the measurement range to be changed several times by changing the time constant which varies over discrete values and adopts that corresponding to the measured frequency for a given accuracy. The frequency meter which we present here gives three values of the accuracy, i. e. three groups of variable time constants, and operates as a chronometer and as a conventional frequency meter. The object is to describe the construction of a variable time-constant system and it is obvious that further work would lead, because of new industrial circuits, to great improvements in the design of the apparatus.

L'interet de ce frequencemetre est de limiter sa precision a une valeur fixee a l'avance pour toute la gamme de frequence a mesurer. Pour cela, il lui est possible de changer la gamme de mesure plusieurs fois en changeant sa constante de temps qui varie par valeurs discretes pour prendre celle correspondante a la frequence mesuree pour une precision donnee. Le frequencemetre que nous proposons affiche trois valeurs de precision, donc trois groupes de constantes, de temps variables et fonctionne en chronometre et en frequencemetre classique. Son but est de montrer la realisation du systeme a constance de temps variable et il est evident qu'une seconde etude amenerait, de par les circuits industriels nouveaux, de grandes ameliorations, dans la conception de l'appareil.
