It is a powerful tool for scientific research. However, the high repetition rate XFEL has a high peak power and average power. The high peak power can damage optics and devices in the optical path in femtosecond. And the high average power will cause the distortion of optics. Consequently, it becomes crucial to protect optics and devices in the optical path. This shutter system is designed to protect the diagnostics and avoid thermal distortion and thermal damage. It can control the number of pulses and average power on the diagnostics. The time window of shutter can be as small as 10 ms. It has can absorb most of FEL power.
