WebJun 11, 2024 · Novel beam physics experiments with proton beams in CERN's Super Proton Synchrotron (SPS) were performed to demonstrate several critical aspects for the operation of crab cavities in the future HL-LHC including transparency with a pair of cavities, a full characterization of the cavity impedance with high beam currents, controlled emittance ... WebCrab Cavity Induced Vertex Smearing (25 mrad) RMS hadron bunch length ~10cm*. •Because of the rotation, the Roman Pots+otherFF detectors effectively see the bunch crossing smeared in x. •Vertex smearing = 12.5mrad (half the crossing angle) * 10cm = 1.25 mm •If the effective vertex smearing was for a 1cm bunch, we would have 0.125mm labor law cayman islands
