论文摘要
梁诊断对于平滑的加速器操作至关重要。许多技术依赖于仪器，其中梁特性受测量显着影响。新颖的方法旨在使用Cherenkov衍射辐射（CHDR）进行非侵入性诊断。与常规的Cherenkov辐射不同，带电的颗粒不必在介质内移动，但是只要它们比介质中的光速快，它们就足够在附近移动。因此，由于CHDR测量值而导致的梁特性的变化可以忽略不计。为了检查在不同条件下的CHDR发射，我们将融合的二氧化硅散热器放在DESY II测试梁中。我们观察到电子和正电子力量在1 GeV/c和5 GeV/c之间的线性增加。此外，我们发现电子产生的CHDR明显比正电子的增加，以增加颗粒动量。结果表明，需要通过电子和正面来进一步研究CHDR的生成，并可能在未来光束诊断设备的设计中找到应用。
Beam diagnostics are crucial for smooth accelerator operations. Many techniques rely on instrumentation in which the beam properties are significantly affected by the measurement. Novel approaches aim to use Cherenkov Diffraction Radiation (ChDR) for non-invasive diagnostics. Unlike regular Cherenkov Radiation, the charged particles do not have to move inside of the medium, but it is sufficient for them to move in its vicinity as long as they are faster than the speed of light in the medium. Changes to the beam properties due to ChDR measurements are consequently negligible. To examine ChDR emission under different conditions, we placed a fused silica radiator in the DESY II Test Beam. We observed a linear increase in ChDR intensity for electron and positron momenta between 1 GeV/c and 5 GeV/c. Additionally, we found that electrons produce significantly more ChDR than positrons for increasing particle momenta. The results suggest a need for further research into the ChDR generation by electrons and positrons and may find application in the design of future beam diagnostic devices.
