Data Acquisition Team

Takaki Hatsui
Team Leader
The team has carried out the R&D on fast detectors, two-dimensional detectors and fast data acquisition system with high precision for the XFEL facility, SACLA, and accelerated the XFEL science. We expand our capability on top of these infrastructure by developing new detection, data acquisition, and data analysis technologies. We devote ourselves especially to the acceleration of X-ray science through the invention of new detection scheme by employing the state-of-art very large scale integration (VLSI) technology.
