Abstract

PROCEDE ET DISPOSITIF DE MESURE DU TAUX MASSIQUE DE FUITE D'UNE ENCEINTE CONTENANT UN GAZ. UN LASER 1 EMET UN FAISCEAU 2 A DEUX LONGUEURS D'ONDE SUR UN INTERFEROMETRE DE MICHELSON A LAMES SEMI-REFLECHISSANTES 3 ET 8. LE FAISCEAU SECONDAIRE 4 PARCOURT UNE LONGUEUR DE BASE DANS L'ENCEINTE E. DES DETECTEURS PHOTOELECTRIQUES 13 ET 14 PRECEDES DE FILTRES MONOCHROMATEURS 11 ET 12 COMPTENT LES DEFILEMENTS DE FRANGES. LES NOMBRES COMPTES COMPRENNENT DEUX TERMES FONCTIONS, L'UN D'UN TAUX DE FUITE ET LE SECOND DES VARIATIONS DE LONGUEUR DE BASE. LE CALCULATEUR 17 EFFECTUE LA COMPENSATION DES DEUX SECONDS TERMES. APPLICATION AU CONTROLE D'ENCEINTES DE CONFINEMENT DE CENTRALES NUCLEAIRES.
