Abstract	his note summarizes the program of the LHC Machine Development to assess the potential and limits of the long-range beam-beam compensators held in 2017 (MD2202). Two compensator prototypes were installed in the machine during the EYETS16-17 and the first evidence of compensation were observed during the MD block 1 (FILLS 5898 and 5900, 9 h assigned on 1st July 2017).This study was also scheduled for the MD block 3 but could not be performed due to the machine unavailability (9 h assigned, 2 h available but unfortunately not exploitable for measurements). In MD block 4 an additional slot was scheduled (FILLS 6434 and 6435, 10 h on 29th November 2017)
