LHC MD2930: Asynchronous Beam Dump Test with Bunched Beam

This note summarises the results of LHC Machine Development (MD) 2930, which studied the beam-loss behaviour during asynchronous beam dumps at 450 GeV and at 6.5 TeV using bunched beam in the abort gap. The MD consisted of three main parts. First, single pilot bunches were injected into the abort ga...

description This note summarises the results of LHC Machine Development (MD) 2930, which studied the beam-loss behaviour during asynchronous beam dumps at 450 GeV and at 6.5 TeV using bunched beam in the abort gap. The MD consisted of three main parts. First, single pilot bunches were injected into the abort gap, dumped and the resulting beam loss patterns were recorded. Second, trains of 48 bunches were injected into the abort gap with successively increasing bunch intensity and dumped. No quenches of superconducting magnets were observed up to a bunch intensity of 1.25e11 protons. In the last part, single pilots were ramped to 6.5 TeV. The last dump caused the beam-induced quench of the MQY.4R6, the MB.A8R6 and the MQY.4L6 magnets.
