77th IUVSTA Workshop
Surface Processes, Gas Dynamics, and Vacuum
Technology of Cryogenic Vacuum Systems
Fuefuki, Japan
August 17-21, 2016!
1st Circular!

November 19, 2015

In the various modern applications of vacuum technology, the presence of a lowtemperature surface in a vacuum system is very common. The behaviour ofsuch a system is often determined by the physical process at the cold surface.
At this workshop, the physical basis of gas-surface processes at the cold
surface and related phenomena will be discussed.

!

This is a workshop which is intended to provide a forum for intense debate anddiscussion between a small number of experts in the ﬁeld of science andtechnology of cryogenic vacuum systems. The workshop will be organized asfollows: Oral presentations will be given by invited speakers, 50 min in length
including discussion. Posters will be presented by the other participants and will
be displayed during the workshop for discussion. The number of posters will be
25 at the most. Poster presentations are selected by the program committee on
the basis of their expertise on the topics. All delegates will stay at the same
hotel together.
