Studies and implementation of the PS dummy septum to mitigate irradiation of magnetic septum in straight section 16

During the commissioning phase of the PS Multi-Turn Extraction (MTE) and the following operational period a number of limitations were observed, namely activation of the magnetic septum in straight section 16, fluctuation of the fraction of particles trapped in the islands, and instabilities of the...

Sumario:During the commissioning phase of the PS Multi-Turn Extraction (MTE) and the following operational period a number of limitations were observed, namely activation of the magnetic septum in straight section 16, fluctuation of the fraction of particles trapped in the islands, and instabilities of the injection trajectories in the SPS. These issues have been addressed in many ways, by either dedicated measurement campaigns or paper studies to determine mitigation measures. In this document the proposed solution of installing a dummy septum in straight section 15 of the PS ring to reduce the activation of the extraction magnetic septum is described in details.
