Brief Introduction

The Beam Diagnostics Group focuses on the beam measurement and diagnostics technology research of particle accelerators, and provides high-quality services on the design, manufacturing, testing and integration of beam diagnostics system. There are currently 18 members in the group. The group is composed of six technical teams, including non-destructive physical design team, destructive physical design team, data acquisition and control team, beam diagnostic electronics team, mechanical design team and beam diagnostics operation and maintenance team. 

The group has mature technologies and rice experiences in beam position, phase probe, beam intensity, beam size measurement and slow beam extraction.
