LEIR beam instrumentation

The Low Energy Ion Ring (LEIR) is central to the 'Ions for LHC' project. Its role is to transform a series of long low intensity ion pulses from Linac-3 into short high density pulses, which will be further accelerated in the PS and SPS rings, before injection into LHC. To do so the injected pulses are stacked and phase space cooled using electron cooling, before acceleration to the ejection energy of 72 MeV/u. This note describes different types of instruments which will be installed in the LEIR ring and transfer lines. These instruments are dedicated to the measurement of beam position, beam intensity, beam emittance, beam profiles and to the collection of information on bunched beams
