摘要

气体衰减器是为软x射线光束提供精确的光子强度变化的重要装置。在SwissFEL ATHOS波束线前端空间非常有限，采用了一种创新的方法来提供高达1200 eV能量的三个数量级的衰减。差动抽气系统真空歧管的增材制造可以在不到半米的空间内实现三重抽气阶段。测量结果表明，该装置的响应符合理论计算的预期。

A compact gas attenuator for the SwissFEL ATHOS beamline realized using additive manufacturing.

Gas attenuators are important devices providing accurate variation of photon intensity for soft X-ray beamlines. In the SwissFEL ATHOS beamline front-end the space is very limited and an innovative approach has been taken to provide attenuation of three orders of magnitude up to an energy of 1200 eV. Additive manufacturing of a differential pumping system vacuum manifold allowed a triple pumping stage to be realized in a space of less than half a meter. Measurements have shown that the response of the device is as expected from theoretical calculations.
