Sumario:This report summarizes the results of the backup activity performed after cancellation of the MD1787. This MD was originally conceived to measure the instability growth rate versus chromaticity and damper settings at injections energy in the LHC, but, due to an RFQ issue in the Linac2 followed by an issue with the LHC cryogenic system, the original plan could not be executed. As a short backup activity on the available time given by the daylight saving on 30th October 2016 and the kind cooperation with other LHC MD users, it was decided to characterize with beam the TDI impedance.
