BCMS - 2021

Intensity

Showing intensity after injection (PR.DCAFTINJ_2) and before extraction (PR.DCBEFEJE_1) for the BCMS beam (LHC as destionation, LSA name contains BCMS and 48b).

Beam Transmission

Showing transmission for the 48b BCMS beam (LHC as destionation, LSA name contains BCMS and 48b) as follows:

• Beam transmission in the ring: ratio between intensity before extraction and intensity after injection: PR.DCBEFEJE_1:INTENSITY / PR.DCAFTINJ_1:INTENSITY.

• Beam transmission in the transfer line: ratio between intensity in the last BCT of the line and intensity before extraction: F16.BCT.372 / PR.DCBEFEJE_1:INTENSITY.

TT2 trajectories

Showing horizontal trajectories in TT2 for the 48b BCMS beam.

Nxcals variable: F16.BPM.

Showing vertical trajectories in TT2 for the 48b BCMS beam.

Nxcals variable: F16.BPM.

Limitation Diagram

BCMS limitation diagram before PS extraction and corresponding emittance data obtained since the start of the 2021 LHC physics run. To compare to pre-LS2 excluded areas, select the corresponding scenario from the dropdown menu.

Transverse emittance evolution

Showing the transverse emittance measured with the wire scanners since the beginning of the 2021 LHC physics run. Emittance measurements take place every day and, if time permits, before every LHC fill.
