The International Union for Vacuum Science, Technique, and Applications (IUVSTA) is a union of 35 science and technology national member societies that supports collaboration in vacuum science, technique and applications.
Founded in 1958, IUVSTA is an interdisciplinary union which represents several thousands of physicists, chemists, materials scientists, engineers and technologists who are active in basic and applied research, development, manufacturing, sales and education. IUVSTA finances advanced scientific workshops, international schools and technical courses, worldwide.
The main purposes of the IUVSTA are to organize and sponsor international conferences and educational activities, as well as to facilitate research and technological developments in the field of vacuum science and its applications.
The history and structure of the Union are described in two articles[1][2] in scientific journals.
IUVSTA is a Union (or federation) of National Vacuum Societies. There can be only one member society (or National Committee) in any one nation. This Society must be representative of the scientific and technical fields encompassed by the Divisions of IUVSTA. Where appropriate a Society can represent more than one nation. IUVSTA can only recognise societies in geographical areas recognised by the United Nations as independent nations.
IUVSTA maintains formal links with other Non-Government Organizations involved in education, and the promotion and dissemination of science and associated techniques. With the support of IUVSTA divisions, fruitful cooperation with UNESCO, ISC, ICTP and TWAS have been initiated and developed. Such contacts facilitate the organization of specialized workshops and may offer financial support for students attending short courses, seminars and congresses. Links with other organizations such as ISO are the responsibility of the IUVSTA divisions.
IUVSTA has been admitted to UNESCO in the “Relations Operationnelles” category.[7]
IUVSTA is a Scientific Associate of the International Science Council (formerly International Council of Scientific Unions, ICSU) [8]
IUVSTA cooperates financially and scientifically with International Centre for Theoretical Physics (ICTP) in the organization of workshops of high scientific level held in Trieste. These workshops address a post-graduate and post-doctoral audience from the lesser developed countries.[9]
Preliminary contacts have been made with Third World Academy of Sciences (TWAS) which foresees the organization of short courses on rough vacuum techniques and applications dedicated to technicians.
IUVSTA has a formal liaison with the International Standards Organization (ISO). IUVSTA sends a representative to the TC/201 Surface Chemical Analysis committee and to the ISO TC/112 Vacuum Technology committee. These links are maintained via the Applied Surface Science and Vacuum Science and Technology divisions, respectively.[10]
