IR8 Aperture Measurements at injection energy

This report describes aperture measurements in the IR8 triplet region performed during the MD block 4 on 29 of November 2012. The goal was to determine whether the available aperture in the triplets is sufficient to apply a two-dimensional separation scheme for the future 25 ns runs of the LHC. The...

description This report describes aperture measurements in the IR8 triplet region performed during the MD block 4 on 29 of November 2012. The goal was to determine whether the available aperture in the triplets is sufficient to apply a two-dimensional separation scheme for the future 25 ns runs of the LHC. The limiting plane for the intended separation scheme is the vertical one. For the measurement, proton beams at 450 GeV in the injection optics configuration were used. The vertical separation bump is increased until losses are observed. To obtain independent measurements in both triplets additional bumps from the outer corrector magnets have been used, generated by YASP. Measurements have been done with and without horizontal crossing angle.
