Level-1 Trigger Development for the Multi-band Instability Monitor

Prototype studies in 2012/13 have shown that the newly developed multi-band instability monitor (MIM) can provide sub-micrometer resolutions for intra-bunch and head-tail beam position measurements. This talk presents the proposed design for a new on-line beam instability trigger. As an exploitation of the MIM's very high sensitivity, it aims to detect instabilities during their onsets and to estimate their lifetime. The generated trigger will be used to synchronise the acquisition of the other LHC beam instrumentation systems to aid a better diagnostic and mitigation of these instabilities.
