Recommissioning of the RF system after the SRS upgrade

The SRS has been upgraded with the installation of two high-field multipole wiggler (MPW) insertion devices. The four RF cavities have been relocated to enable the MPW's to be installed in the appropriate straights. As a consequence, the whole of the high power RF system, including the essential services, has been reconfigured. The changes to the system and the recommissioning details are presented.
