电子云的形成是 LHC 光束高于标称强度时 SPS 运行的主要限制。这些光束被设想在 LHC 光度升级的框架中，并将通过新的注入器 LPSPL 和 PS2 提供。为了确定通过在现有的 SPS 真空室上涂上非晶碳薄膜来抑制电子倍增的可能方法，已经进行了一系列研究。在介绍了 SPS 中安装的实验装置后，将介绍 2008 年使用光束进行的测试结果。
Electron cloud build-up is a major limitation for the operation of the SPS with LHC beam above nominal intensity. These beams are envisaged in the frame of the LHC luminosity upgrade and will be available from the new injectors LPSPL and PS2. A series of studies have been conducted in order to identify possible means to suppress electron multipacting by coating the existing SPS vacuum chambers with thin films of amorphous carbon. After a description of the experimental apparatus installed in the SPS, the results of the tests performed with beam in 2008 will be presented.
