Recurring sources of premature beam dumps

While the fraction of premature beam dumps has considerable decreased during the 2016 Run in favour of programmed end of fill dumps, still 1 out of 2 beam aborts are non-programmed. The root causes of these are primarily equipment failures as well as UFOs and electrical perturbations. In this contri...

Sumario:While the fraction of premature beam dumps has considerable decreased during the 2016 Run in favour of programmed end of fill dumps, still 1 out of 2 beam aborts are non-programmed. The root causes of these are primarily equipment failures as well as UFOs and electrical perturbations. In this contribution we will analyse the premature beam dumps observed in 2016, with an emphasis on identifying recurring failures. An outlook on the planned mitigation strategies for the main contributors to the failure statistics will conclude this paper.
