11th Workshop on RF Superconductivity

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 1010.

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

Status reports on laboratory activities

Future developments

  - Proposals for new superconducting accelerators

Cancellation prior to August 22, 2003: a 50 EUR cancellation fee will apply. No refunds will be made after August 22, 2003. All refunds will be made after the end of the workshop.

Invitation Letters

If you need an invitation letter in order to get a visa to attend the workshop, please fill out the visa requirements section on the registration form carefully. In case of additional questions please send an e-mail to

Ground Transportation

By plane: Travemünde is easily 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.

Student Support

A limited amount of money is available to support student participation at SRF2003. Students have to apply for financial support by sending a letter of recommendation written by their supervisor not later that July 15, 2003. Letters should be mailed or faxed to:
