Description
The mission of the TESLA Technology Collaboration (TTC) is to advance superconducting RF (SRF) accelerator R & D and related accelerator studies across the broad diversity of scientific applications, and to keep open and provide a bridge for communication and sharing of ideas, developments, and testing across associated projects.
To this end the Collaboration supports and encourages free and open exchange of scientific and technical knowledge, expertise, engineering designs, and equipment.
We cordially welcome you to join the TTC meeting, hosted by the Institute for Rare Isotope Science (IRIS/IBS), and to be held at the Science Culture Center (map) in Daejeon, Korea on April 8-11, 2025.
