RIKEN SPring-8 Center Novel Light Source Development Team
Team Leader: Toshiteru Kii (D.Sc.)
Research Summary
By giving acceleration to charged particles, synchrotron radiation can be generated. Synchrotron radiation facilities usually use permanent magnets to apply a strong force to wiggle the charged particles, whereas the use of superconducting technology has the potential to significantly increase this force, leading to a significant reduction in the size and improvement in the performance of synchrotron radiation facilities.
The Special Light Source Development Team will conduct research and development to realize a new type of high-field, short-period undulator using bulk superconductors, not wires or thin films, for the further development and innovation of synchrotron radiation facilities.
