Low Energy Ion Rings (LEIR) Project

This project aims at modifying the LEAR machine for its new rôle as an ion accumulator for LHC. This involves (i) the accumulation of ions by using coupled longitudinal-transverse multiturn injection, (ii) cooling of the beam injected by means of an electron cooling, (iii) multi injection and stacking if needed until the number of ions required for LHC is reached, (iv) acceleration and extraction to the PS machine.
