Integration Location HEL to be integrated into HL-LHC collimation system. Proposed locations for the electron lenses are RB-44 and RB-46 at Point 4, on each side of the interaction region IR 4. • Beam to beam distance 420 mm • Limited longitudinal space for Survey and Transport restrictions. • Connections 17/08/2017
