Collision tunes at injection and ramp

Sumario:This paper reports on the first successful attempt to inject and ramp LHC beams with collision tunes. Using the same tunes throughout the entire LHC cycle has three clear advantages: • Shorter squeeze sequence and hence saving time for luminosity production. • Less complexity in the operation of feed-backs. • Absence of tune swing crossing 7th and 10th order resonances.
