The Superconducting Testing Facility (STF) is a project at KEK, Japan to build and operate a test linac with high-gradient superconducting cavities KEK STF website. Its phase I will have a 4-cavity chained superstructure shown in the following,
The STF 4-cavity superstructure was simulated at NCCS through an INCTIE/LCF award. The following shows the electromagnetic field distribution of a trapped dipole mode in the STF superstructure.
Click here to see an animated gif picture which shows the field distribution of the trapped mode as one traverses along the structure.
