Conferences and Symposia

Second European Symposium "Vacuum "

THE Deutscher Arbeitskreis Vakuum (DAV), sponsored by D E C H E M A Deutsche Gesellschaft fur chemisches Apparate- wesen, Nachrichtentechnische Gesellschaft im VDE (NTG), Verband Deutscher Physikalischer Gesellschaften and Ver- fahrenstechnische Gesellschaft im Verein Deutscher Ingenieure, has arranged the Second European Symposium " Vacuum ", 46th Event of the European Federation of Chemical Engineering, which is to be held on 5-7 June 1963 at Frankfurt-am-Main, Germany. The general subject will be " Physics and Technology of Sorption and Desorpt ion Effects at Low Pressures ".

The four themes for discussion are :

(a) Phenomena of physico-chemical interactions of gases or vapours and solid mater ia l : sorption, desorption, solu- bility and diffusion ;

(b) Partial pressure measurements and suitable meters ; (c) Techniques and applications : application of sorption to

achieve low pressures, and preparat ion and degassing of single components and complete vacuum installations under special consideration of the partial pressure analysis ; and

(d) Sorption and desorption in special equipments such as particle accelerators, fusion equipments and space chambers.

The Programme includes papers by the following :

J. Yarwood and K. J. Close (United K ingdom) ; K. Peters

(Aust r ia) ; H. L. Eschbach, F. Gross, K. Mauersberger and S. Schulien (Germany) ; the late R. Jaeckel and B. Wagner (Germany) ; D. A. Degras (France) ; Y. Larher and R. Bir (France) ; H.
