肖特基势垒二极管（SBD）以其低噪声、超快响应和出色的灵敏度而闻名。它们通常被实现为毫米波长范围内的探测器。微束团不稳定性（MBI）已经在世界各地的许多光源中被检测到，包括英国的钻石光源。这些MBI可以导致毫米波长的相干同步辐射（CSR）的爆发。需要对MBI的动力学进行更多的研究，以确认模拟并最终利用CSR爆发的力量。一个单次发射光谱仪已被设计，并正在运行中的钻石光源（DLS）。它由8个SBD组成，范围从33-1000 GHz。与以前进行的测量不同，每个SBD都被单独表征，从而使获得的结果与模拟结果相当。在本文中，我们提出的评估，每个SBD的光谱仪和光谱仪的使用中的光束的第一个结果。
Schottky barrier diodes (SBDs) are known for their low noise, ultra-fast response and excellent sensitivity. They are often implemented as detectors in the millimetre wavelength regime. Micro-bunch instabilities (MBI) have been detected at many light sources around the world including the Diamond Light Source, UK. These MBI can result in bursts of coherent synchrotron radiation (CSR) with millimetre wavelengths. More research needs to be carried out with regards to the dynamics of MBI in order to confirm the simulations and to eventually harness the power of the CSR bursts. A single shot spectrometer has been designed and is under operation at the Diamond Light Source (DLS). It is composed of eight SBDs ranging from 33-1000 GHz. Unlike previous measurements carried out, each of the SBDs has been individually characterised thus making the results obtained comparable to simulations. In this paper, we present the assessment of each SBD in the spectrometer and the first results of the spectrometer's use in the beam.
