在大型强子对撞机中，高振幅粒子被电子感应加速器准直器或动量准直器清洗。在此之前，电子感应加速器的损失已经被更详细地研究，因为它被认为是机器的一个可能的性能限制。在运行的第一年期间的测量表明，在非动量清洁插入中也有很高的损失。这导致了显著的辐射剂量以加热准直器下游的磁体。本文工作的目的是用SixTrack模拟在射频系统接受范围外，由辐射阻尼驱动进入动量准直器的非动量粒子。结果是评估新型被动吸收器保护暖磁体的有效性的重要因素。
In the LHC, high-amplitude particles are cleaned by ei- ther betatron collimators or momentum collimators. Pre- viously, betatron losses have been studied more in detail since considered as a possible performance limitation of the machine. Measurements during the first years of oper- ation show high losses also in the off-momentum cleaning insertion. This causes a significant radiation dose to warm magnets downstream of the collimators. Our work in this paper aims at simulating with SixTrack the off-momentum particles, driven into the momentum collimators by radia- tion damping outside the RF system acceptance. The re- sults are an important ingredient in assessing the effective- ness of new passive absorbers to protect the warm magnets.
