2nd and Final Announcement

Workshop Information

The International Workshop on Superconducting Radio Frequency (SRF) devices was founded in 1983 as a platform of communication for the application of superconductivity for particle acceleration. The workshop is held every two years at various laboratories around the world.
Superconducting radio frequency accelerating systems have grown into a mature technology, more than 1000 meters of SRF cavities have been installed worldwide. Superconducting cavities are under operation in electron storage rings as well as in linear accelerators for electrons, protons and heavy ions.
The most recent project under construction is the neutron spallation source in Oak Ridge, USA. There is vigorous interest in using superconducting accelerating systems in the upgrade of existing installations or in new powerful accelerators for fundamental physics research (such as heavy ions, high intensity electron beams in storage rings, neutrino factories) or applied physics (spallation neutron sources, ultraviolet and X-ray free electron lasers).
The most challenging future project is a 30 km long superconducting linear accelerator, proposed by the TESLA ( Tev Energy Superconducting Linear Accelerator) collaboration for the next linear electron-positron collider. In the past decade the accelerating fields in SRF cavities have been raised from 5 MV/m to more than 25MV/m at quality factors above 10^10.

The SRF Workshop is intended to communicate the latest findings in the field of RF superconductivity, present new developments, stimulate controversial discussions, establish contacts to near-by research areas and, last but not least, to serve as an educational guide for newcomers.

The workshop is organized in form of review talks, invited talks, poster contributions and working groups. It will cover the following topics:

Review of RF superconductivity and superconducting materials

- Basics of RF superconductivity
- Material properties of niobium
- Alternative superconductors for RF application
- Fundamental limits of RF superconductivity

Progress in performance of SRF cavities

- Limitations by field emission, multipacting or thermal instabilities
- Improved preparation methods
- Comparison between theoretical and experimental limitations
- Diagnostic methods for SRF cavities

Technical issues

- RF power input couplers
- Higher-order mode damping
- Lorentz force detuning
- Microphonics
- Frequency tuning
- Fabrication techniques for niobium and niobium-coated copper resonators

Operational aspects

- Energy recovery linacs
- RF control and cryogenic system for continous-wave and pulsed operation
- Analysis of failure modes

Posters on laboratory activities

Future developments

- Proposals for new superconducting accelerators

Scientific Issues


The program can be found in the attached e-mail file as well as on the SRF homepage

Changes of the program as compared to previous workshops

-Laboratory reports will be presented as poster papers in order to have some more time for working groups and reviews. We will find a place to display these posters during the whole workshop so that you have enough time to inform yourself about the lab activities. Please do not forget to send your abstract in time.
-We have several tutorials late pm for new comers (and experts, too)
-We have several working groups, some might be in parallel. The exact schedule will be based on your voting for attendance at the beginning of the workshop.
-One minor technical change: we will note distribute conference bags ( but paper and pencils) because most of you have many already, please bring yours with you. The money saving goes into students support.

Call for Abstracts

Abstract submission is open since July 4, 2003. It will be closed on August 1, 2003.
If you need to change your abstracts, please send an e-mail to stating clearly the desired changes (e.g. further authors, correction of "mistakes" etc). You can only submit an abstract if you are a participant of the SRF workshop.
Abstracts will be published on the web as pdf file in the second half of August.

Call for Papers/Preparation of Papers

Paper submission will start on August 18, 2003. Guidelines for the preparation of manuscripts and papers are under preparation and will be published on the SRF homepage soon.


Contributions to the 11 SRF Workshop will be published on the Web and as CD. There will be no paper proceedings.

Poster Sessions

The poster sessions will be held on Monday, Tuesday and Thursday from 14:30 to 17:30 h. Posters should be mounted half an hour before the poster sessions will start with drawing pins on pin-boards which will be provided. At the end of each poster session the posters have to be dismounted (except posters with laboratory reports). The space that can be used for displaying information is 1.32 m high and 0.93 m wide. The posters will be grouped by topics. Authors will get the information when his/her poster is presented and at what position in the poster session roomm in the beginning of August.

Organisational Issues

Opening hours

Shuttle on Sunday Sept. 7

There will be buses from Hamburg Airport to Travemuende – Maritim at

9:00, 11:00, 14:30, 17:00 and 20:00 h.

This is today’s planning. If the actual needs differ from this schedule, the schedule will be changed. Information will be updated regularly.

Afternoon Schedule for Friday, Sept. 12/Shuttle

TTF Tour at DESY

Details of the tour will be published at the SRF homepage soon. Please also check the DESY home page for some details about the TTF and TESLA project.
On Friday, Sept. 12 a tour to DESY is offered. We will leave Travemuende at noon.
There will be a shuttle service organized in the following way:
13:00 Maritim Travemuende – DESY, Hamburg
If, after the TTF tour at DESY, you want to get to Hamburg Airport, there is a bus leaving at

Ground Transportation

By plane:
Travemünde is accessible from Airport Hamburg- Fuhlsbüttel, Germany within approx. 2 hours by public transportation. We will organize a shuttle on Sunday. The other days you should take the Airport Express (Jasper Bus) to Hauptbahnhof (main station) and change to the train there (see below). In other words: you have to travel within Hamburg from the Airport to main station, there you take a train to Lübeck where you will have to change trains.

Other possibilities are:

By train:
You can reach Travemünde from all directions. The station is is in walking distance (only 800 m) from the hotel. There is a train service
between Lübeck and Travemünde every 30 minutes. For detailed information see the web page of die Bahn DB (
By car:
Travemünde is only 15 km from Lübeck. From Hamburg and Hamburg Airport you take the A1 (freeway) Hamburg - Lübeck or Puttgarden - Lübeck. From Hamburg it takes approximately 50 minutes to reach Travemünde.
On the Lübeck tourism Web page:, click Lübeck - Directions on the blue bar. You will receive a map of Germany showing the freeways leading to Travemünde/Lübeck.
