AbstractAbstract
[en] In 1977 the three major functions of ILL continued to be performed (provision of neutron beams at the high flux reactor, development of advanced instrumentation, workshop organization). An integrated programme of improvement to the existing instruments and of new instrument construction, was carried out. A high priority was given to finishing instruments in the course of construction and both the ultra cold neutron source, PN5, and spin echo spectrometer, IN11, came into operation. No new instrument construction was started; even so, the completion of D18 (the interferometer) and IN12 (the cold three-axis machine) was delayed until 1978. Some advantage was taken of the delay to implement a new system of three-axis drive mechanics and interfacing electronics. This report gives a survey of the state of the experimental facilities at ILL and the scientific work carried out in 1977, and of the main technical and administrative activites of the Institute. Chapters correspond to the various colleges (theory, fundamental and nuclear physics, excitations, structures, liquid, gases and amorphous materials, impurities, structural biology and chemistry), reactor operation and instrument support services, computing services... A second volume of this report contains more detailed descriptions of the individual experiments

En 1977, les trois principales missions de l'ILL ont continue a etre remplies (fourniture de faisceaux de neutrons au reacteur a haut flux, developpement d'une instrumentation de pointe, organisation de groupes de travail). Un programme d'amelioration des instruments existant et de construction de nouveaux instruments a ete realise. Priorite, a ete donnee a la finition des instruments en cours de construction et la source de neutrons ultra froids, PN5, et le spectrometre a echo de spin, IN 11, sont tous deux entres en service. Aucun nouvel instrument n'a ete mis en chantier; et meme, l'achevement de D18 (l'interferometre) et de IN12 (la machine a neutrons froids a trois axes) a ete repousse a 1978. On a profite de ce delai pour executer un nouveau systeme de commande necanique tri-axial et d'interfaces electroniques. Ce rapport donne une vue d'ensemble de l'etat des installations experimentales de l'ILL et des travaux scientifiques et des activites administratives de l'Institut. Les chapitres correspondent aux differents colleges (theorie, physique fondamentale et nucleaire, excitations, structures, liquides, gaz et matieres amorphes, impuretes, biologie et chimie structurales), au fonctionnement du reacteur et aux services supports des instruments, aux services de calcul...
