Research Summary

Naruhiko  Sakamoto(D.Sci.)

We develop new components for accelerators dedicated for low-beta-ions with very high intensity. Specifically, we design and build a cryomodule for superconducting linac efficient for acceleration of low-beta-ions. In parallel, we optimize an rf acceleration system by making computer simulations for acceleration of very high intensity beams.
