The combined 11
th
International Vacuum
Congress and 7
th
International Conference
on Solid Surfaces were hosted by the
German Vacuum Society (Deutsche
Arbeitsgemeinschaft Vakuum, DAGV).
These meetings were held from 25 to
29 September 1989 in the Cologne
Convention Centre (Köln Messe) in Cologne
in the Federal Republic of Germany. The
Chairs of the Organising and Program
Committees were A. Benninghoven and
H. Bonzel, respectively. The concept of
offering limited-period registration was
continued at this congress. The attendance
included 1092 full registrations, 52 two-day
and 144 one-day registrations, 319 students
and 125 companions, with 39 countries
being represented. There were 91 plenary
and invited papers plus 917 contributed
papers, including 300 from students. The
breakdown of papers by Divisions was
114 ASS, 134 EMP, 26 FT, 378 SS, 177 TF,
24 VM and 155 VS. The Proceedings were
all published in the archival journal Vacuum
(Volume 41, 1990) by Pergamon Press. The
hard-cover copies of the Proceedings were
grouped in three volumes: SS; EMP + TF
+ FT; ASS + VS + VM. A very successful
exhibition of scientific equipment was held
with 64 exhibitors occupying 1929 square
metres of space. The registration fees
were: DM 600 for full registration, including
the Proceedings, DM 120 for students,
and DM 220 and DM 440 for 1- and 2-day
registrations respectively. After the congress
the German Vacuum Society made a
donation of DM 50,000 (SFr 44,525) to the
IUVSTA.
The Congress in 1992 was to have
been hosted by the Brazilian Vacuum
Society in Rio de Janeiro. This had been
agreed by the Executive Council in 1986
and N. G. Dhere was to have been the
Conference Chairman. However, at the
59
th
Executive Council meeting in April
1989, the Secretary General announced
that he had received a fax message from
the President of the Brazilian Vacuum
Society to say that, regrettably, they must
withdraw their offer to host the 1992
Congress. The CPC proposed that the
society that had polled second in the vote
to choose the host for this congress be
approached. Thus it was that, with a lead-
time of only about 3 years, the Netherlands
Vacuum Society (NEVAC) agreed to take
on the duties of host nation.
