HL-LHC原型蟹状腔安装在CERN SPS中，这将首次允许使用高能质子进行全面的束流测试。由于在机器中安装螃蟹腔进行实验束动力学研究的时间有限，因此需要做好充分的准备。其中一个主要的问题是诱导发射度的增长，在螃蟹腔的相位振幅抖动驱动。在这方面，在过去的几年中进行了几个机器开发（MD）的研究，以量化和表征的长期发射度演变的质子束在SPS。在这些会议记录中，总结了过去几年的实验观察，并介绍了2016年和2017年的MD研究。
The HL-LHC prototype crab-cavities are installed in the CERN SPS, which, for the first time, will allow for a comprehensive beam test with high energy protons. As the time available for experimental beam dynamics studies with the crab cavities installed in the machine will be limited, a very good preparation is required. One of the main concerns is the induced emittance growth, driven by phase amplitude jitter in the crab cavities. In this respect, several machine development (MD) studies were performed during the past years to quantify and characterize the long term emittance evolution of proton beams in the SPS. In these proceedings, the experimental observations from past years are summarized and the MD studies from 2016 and 2017 are presented.
