| 摘要 | 本发明公开了一种硬X射线自由电子激光固体衰减器及衰减控制方法，包括前衰减臂、后衰减臂、真空腔体、运动控制系统和控制电脑系统，所述前衰减臂的衰减片一和后衰减臂的衰减片二在真空腔体内相对设置，运动控制系统分别与前衰减臂和后衰减臂连接，用于控制前衰减臂和后衰减臂相对运动，使得衰减片一和衰减片二在X射线自由电子激光光束上组合形成不同的厚度满足衰减需求，控制电脑系统与运动控制系统连接，用于根据衰减需求计算前衰减臂和后衰减臂的运动距离并向运动控制系统发出控制指令。本发明通过调节衰减片之间的相对位移距离即可实现不同能量下、不同衰减量级衰减片厚度连续调节，满足多种衰减需求。 |
| 翻译摘要 | The invention discloses a hard X-ray free electron laser solid attenuator and an attenuation control method. The hard X-ray free electron laser solid attenuator comprises a front attenuation arm, a rear attenuation arm, a vacuum cavity, a motion control system and a control computer system. An attenuation sheet I of the front attenuation arm and an attenuation sheet II of the rear attenuation armare oppositely arranged in the vacuum cavity; the motion control system is respectively connected with the front attenuation arm and the rear attenuation arm, and is used for controlling relative movement of the front attenuation arm and the rear attenuation arm, so that the attenuation sheet I and the attenuation sheet II are combined on the X-ray free electron laser beam to form different thicknesses to meet the attenuation requirements; and the control computer system is connected with the motion control system and used for calculating the motion distance between the front attenuation arm and the rear attenuation arm according to the attenuation requirements and sending a control instruction to the motion control system. By adjusting the relative displacement distance between the attenuation sheets, the thickness of the attenuation sheets of different attenuation magnitudes can be continuously adjusted under different energies, and various attenuation requirements are met. |
