|Machine Cycle||The machine cycle refers to one complete operation cycle of a machine, i.e. injection, ramp up, possible collision flat top, ejection and ramp down. The minimum cycle time refers to the minimum time required for a complete machine cycle.|
|Machine statistics||run time: annual time allocated to running with beam [days].
scheduled physics time: annual time allocated to physics (excluding initial beam commissioning, scrubbing, TS, recovery from TS, MDs, special physics) [days].
physics efficieny: time with both beams present and stable beams, versus scheduled physics time [%].
machine availability: time when machine is in a state allowing operations to take beam and run through nominal physics cycle, versus run time [%].
turnaround time: Time between the end of one and the start of the next physics run / data taking by the experiments (delimited by the loss of beam presence/beam dump back to declaration of STABLE_BEAMS) [hours].
recovery time: Time between the end of one and the readiness for injection of new particles of the next (delimited by the loss of beam presence/beam dump and resuming of the normal operational cycle) [hours].
|Magnet quench||Loss of the superconducting state in the coils of a superconducting magnet.|
|Main lattice magnets||Main magnets of the LHC arcs, i.q. the arc dipole and quadrupole magnets.|
|Matching section||Arrangement of quadrupole magnets located between the dispersion suppressor and the triplet magnets (or the IP for those insertions without triplet magnets). Each insertion has two matching sections: one upstream and one downstream from the IP.|
