November 8-11, 1977: Twentyfourth National Vacuum Symposium The Twentyfourth National Vacuum Symposium of the American Vacuum Society is to be held in Boston, Massachusetts, on November 8 - 1 1 , 1977. Each of the Divisions of the American Vacuum Society will sponsor technical sessions dealing with applied technologies as well as basic studies. Among the topics to be covered are the following. Surface Science Division: adsorption and surface chemistry semiconductor and insulator surfaces electron spectroscopy for surface studies surface structure determination Thin Film Division: reactive ion etching diagnostics during thin film deposition processes preparation and properties of optical thin films new film deposition techniques manufacturing problems in thin film technology Vacuum Technology Division: ion-material interactions cleaning and outgassing of vacuum materials vacuum systen~ for CTR devices gauging and pressure measurement production systems for vacuum processing
The Vacuum Metallurgy Division will sponsor a programme on general vacuum metallurgy. In addition to these topics there will be sessions on all aspects of general vacuum science and technology.

CONFERENCE ANNOUNCEMENTSAND NEWS
Authors wishing to contribute a paper should send an abstract of 150 words or less to Max G. LagaUy, Materials Science Center, University of Wisconsin-Madison, 1500 Johnson Drive, Madison, Wisc. 53706, U.S.A. by July 8th 1977. Several invited papers will also be presented at the Symposium.
A new opportunity for academic space experiments NASA's LDEF (Long Duration Exposure Facility) will offer scientists a new opportunity for space research. The LDEF is a large passive unmanned structure on which over 70 separate self-contained experiment packages will be mounted. It will be carried aloft by the Space Shuttle Transportation System and will be left to orbit the Earth for a number of months; it will then be retrieved and brought back to Earth, and the experiments will be returned to their owners for analysis. The LDEF offers prolonged exposure to the conditions at its orbital altitude of 300 nautical miles: weightlessness, extreme vacuum, high particle and radiation fluxes. A unique feature is the return of materials and instruments at the end of the mission. The Universities Space Research Association (USRA) has been given the task of seeking worthwhile experiments for the LDEF in all fields of science and technology, and in particular from academic scientists. NASA will provide pre-flight acceptance testing, orbital flight and return for experiments endorsed by the USRA. Experimenters will need to secure research funding; the USRA will assist in this, and in all phases of experiment development and management, where necessary.
