The injected LHC beam will be captured, accelerated and stored using a 400 MHz superconducting cavity RF system. (ACS)

A room temperature 200 MHz capture system (ACN) has been designed to reduce injection loss and ease operation. It will be installed at a later stage if the injected emittance is found to increase when intensities much higher than nominal are reached.

Transverse injection errors will be damped by a system of electrostatic deflectors (ADT) that will also ensure transverse beam stability.

Six high sensitivity longitudinal wideband monitors (APW) will be installed to provide high quality reference signals and diagnostics.

Sophisticated Low Level RF feedback and beam control systems are needed to handle the high intensity LHC beams.

Full remote control is needed for all systems, together with extensive monitoring, diagnostic and specialist facilities.

 The RF and Beam Feedback systems in the tunnel are installed on either side of IR4, with power and auxiliary equipment in the UX45 cavern and UL44/46. Faraday cages will be installed in UX45 for Low Level RF equipment. There will be a control area in SR4.
