Sumario:Substantial upgrades were carried out to the MKI beam screen during LSl: MKI heating has not lirrrited LHC operation since LSl, and is not expected to do so during Run 2. Similarly, during LSl, the vacuum systems on the interconnects between MKl magnets were upgraded: as a result there haven't been any issues with SIS vacuum thresholds on the interconnects between adjacent MKls. However, during 2016, dynamic pressure increase on the MKISD-QS interconnect limited the number of bunches that could be injected for Beam 2. The MKIZD kicker magnet caused several issues during 2016, including limiting the length of the field pulse from August onwards and a high impedance contact from October. As a result of firrther deterioration of the high impedance contact the MKIZD was exchanged during TS3. During November the Surveillance Voltage Monitoring system interlocked the MKIZ installation on several occasions. This paper reviews the MKI performance during 2016, the plans for the EYETS and the expected performance during 2017.
