BLM threshold evolution and 2016 proposal

In total, over 5700 changes to the BLM thresholds were made during 2015. The new thresholds are based on the operational experience from Run 1, on new simulation models and on results from quench tests performed so far. Following the first experiences with operation at 6.5 TeV, a series of adjustmen...

Sumario:In total, over 5700 changes to the BLM thresholds were made during 2015. The new thresholds are based on the operational experience from Run 1, on new simulation models and on results from quench tests performed so far. Following the first experiences with operation at 6.5 TeV, a series of adjustments were made throughout the first operational year of Run 2. An overview of the main changes since the start of the LHC operation and their impact on the machine protection will be presented, focusing on the impact on availability during operation in 2015. The paper will conclude by discussing the remaining main updates, and by proposing a threshold strategy for the start-up in 2016.
