Beam Line Development Team

Makina Yabashi
Team Leader
Based on the state-of-the-art technologies of x-ray optics, the Beam Line Development Team are constructing optical systems for enhancing unique abilities of SACLA, and developing optical diagnosis system for precise measurement of beam properties. We try to generate extremely intense x-ray pulses far beyond 1020 Wcm-2 and develop x-ray diagnostics systems in time domain from femto- to atto-seconds. By combining these elemental technologies, we are pioneering new experimental schemes and methods for developing ultrafast x-ray science and x-ray quantum optics.
