On this website the most important quantities describing the performance of the LHC BCMS beams are visualised.

Limitation Diagram

BCMS limitation diagram before PS extraction and corresponding emittance data obtained since the start of the 2022 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 2022 LHC physics run. Emittance measurements take place every day and, if time permits, before every LHC fill.
