| Abstract | This note summarizes three inter-related machine development sessions that were performed in the LHC in the course of 2018. Long-lasting injection oscillations and beam stability at injection were investigated as a function of capture voltage in the MD 3164 on optimal injection voltage. The convergence of bunch lengths during the controlled emittance blow-up applied in the acceleration ramp was studied in the MD 3163. Finally, the bunch distribution at arrival to flat top was observed using peak-detected Schottky spectra in the MD 3166. |
