41st IUVSTA WORKSHOP
Vacuum System Design for particle accelerators:
a multidisciplinary approach
Brdo pri Kranju, Slovenia, 21/06 – 24/06/2004

Organised by the
Institute of Metals And Technology (IMT), Ljubljana, Slovenia

Sponsored by the Vacuum Science Division of the
International Union for Vacuum Science, Technique and Applications
(IUVSTA)

The workshop will take place in hotel Kokra located on Brdo estate, which is divided into two parts: the castle (from 16th century) and an extensive forest area which includes a natural forest and nine artificially stocked lakes. The venue is located in the countryside close to Slovenian part of the Julian Alps, near the city of Kranj and close to Ljubljana airport. (http://www.brdo.com/)

The deadline for the application has been extended to April 15, 2004.

PRINCIPAL THEMES/TOPICS

AIMS OF THE WORKSHOP

IUVSTA Workshops aim to bring together practitioners in a particular field of science for intensive discussions of a topic or topics in that field. To that end, the numbers participating are kept relatively small and participation is by invitation of the organisers. However, persons interested in participating should register their interest so that they may be considered for an invitation.
The topic of Workshop no 41 is Vacuum System Design for Particle Accelerators. It is hoped that those involved in designing or working with all types of particle accelerators ranging from the largest colliding beam machines to small industrial accelerators will be able to contribute their expertise, whether dealing with modest vacuum levels or XHV. Those working in closely related areas, particularly with large scale vacuum systems, will also be able to contribute insights and experience. We seek to discern and to understand commonality of approaches, procedures and processes.
There will be some emphasis on understanding the ways in which vacuum is important for particular types of accelerator and why residual atmospheres may place limitations on the operation of accelerators. Examples of this might be bremsstrahlung production in cyclotrons or synchrotron light sources and electron cloud production in large hadron colliders, although there will be many others.
Topics such as outgassing and desorption will be discussed with practical methods of reducing these to acceptable levels for both room temperature and cryogenic machines. Other topics will include design tools for calculating gas flows and pressure distributions in complex systems. Pumping techniques and measurement of total and partial pressures in often hostile environments will also be covered.
There will be no published proceedings, although a short summary of the workshop will appear on the IUVSTA web site and may be published in a suitable journal.

STRUCTURE OF THE WORKSHOP

The workshop sessions will be structured so that each will start with an invited paper by an expert in a topic followed by a relatively long period of discussion. During this discussion period, participants will be encouraged to make very short presentations of relevance to the topic (3 – 4 minutes; maximum two overheads) to facilitate the discussion. Sessions will be in the morning and late afternoon with a long break between for informal discussions to continue during some sort of enjoyable activity.
An outline programme and application form will be produced shortly and posted on the web site.
