APERTURE AND DELIVERY PRECISION OF THE LHC INJECTION SYSTEM

The main LHC injection elements in interaction regions 2 and 8 comprise the injection septa (MSI), the injection kickers (MKI), together with three families of passive protection devices (TDI, TCDD and TCLI). The apertures of the two circulating beams are detailed for these elements, together with a summary of recent design modifications. The errors in the SPS, the transfer lines and the injection system are analysed, and the expected performance of the system derived, in terms of the expected delivery precision of the injected beam.
