Abstract
| This note describes a collimation quench test performed at the CERN Large Hadron Collider. The test was designed to quantify whether a primary beam power load of 1MW on the betatron collimation system, the High Luminosity LHC design specification, can be sustained without quenching the superconducting dipole magnets in the dispersion suppressor downstream of the straight section housing the collimation system (DS). Beam losses of more than 650kW were induced using the LHC transverse damper at a beam energy of 6.8TeV, without magnet quench. By retracing the secondary LHC collimators, the amount of collimation debris scattered into the DS magnets was increased by roughly 50%, also without magnet quench. |
