Beam 2 Crystal Characterization Measurements with Proton Beams in the LHC

Le résumé fourni par la source

In 2017, two new crystals were installed, with their goniometers, in the counterclockwise Beam 2 (B2) line. These devices, called TCPC, were tested during 2017 in a dedicated machine development (MD) performed on July the 2nd. The bent silicon crystals were characterised with the LHC proton beams, to measure with the LHC beam their bending angles and the overall working order of the new hardware. Tests were preformed at both injection energy and flat top using horizontal and vertical crystal. Loss maps with crystals at 6.5TeV were performed. Two additional MDs were performed on September the 15th and November the 29th, 2017, to study the B2 horizontal crystal after observing in the first test an anomalous behaviour.
