A reliable diagnostic device for free-electron lasers (FELs) is essential for both users and the evaluation of FEL sources and beamline optics. Here, we propose a compact bolometric radiometer (CBR) that can operate at room temperature. The CBR is mainly designed for FELs in the wavelength range from the extreme-ultraviolet (EUV) to x-rays; moreover, we confirmed that the proposed device can also be applied to synchrotron radiation. As an application of the CBR, we evaluated an FEL beamline transmission by means of bolometric technique in the EUV range for the first time, to the best of our knowledge. This indicates that the CBR is an effective diagnostic device for FELs.
一种用于自由电子激光器（FEL）的可靠诊断设备对于用户以及FEL光源和光束线光学器件的评估而言至关重要。在此，我们提出一种可在室温下运行的紧凑型测辐射热计（CBR）。该CBR主要设计用于波长范围从极紫外（EUV）到X射线的FEL；此外，我们证实所提出的设备也可应用于同步辐射。据我们所知，作为CBR的一项应用，我们首次通过测辐射热技术在EUV范围内评估了一条FEL光束线的传输。这表明CBR是一种用于FEL的有效诊断设备。
