Effect of the undulator in IR4 on the LHC beam.
An undulator is installed in IR4 to produce synchrotron radiation. The perturbation it introduces in LHC is examined. It has little effect on the closed orbit, a negligible effect on the tune. Its intrinsic non-linearities are negligible (analysis by ray tracaing). Specifications on the multipole co...

| Sumario: | An undulator is installed in IR4 to produce synchrotron radiation. The perturbation it introduces in LHC is examined. It has little effect on the closed orbit, a negligible effect on the tune. Its intrinsic non-linearities are negligible (analysis by ray tracaing). Specifications on the multipole content of its integrated field are given to produce no effect on the dynamic aperture. |
