ISOLDE, the heavy-ion facility at CERN is undergoing a major upgrade with the installation of a superconducting LINAC that will allow post-acceleration of ion beams up to 10 MeV/u. In this framework, customized beam diagnostics are being developed in order to fulfill the design requirements as well as to fit in the compact diagnostic boxes foreseen. The main detector of this system is a compact Faraday cup that will measure beam intensities in the range of 1 pA to 1 nA. In this contribution, simulation results of electrostatic fields and particle tracking are detailed for different Faraday cup prototypes taking into account the energy spectrum and angle of emission of the ion-induced secondary electrons.

The HIE-ISOLDE project aims at upgrading the CERN ISOLDE radioactive ion beam facility for higher beam intensities and higher beam energies. New beam diagnostic devices have to be developed as part of this upgrade, in particular for the measurement of intensity, energy, transverse and longitudinal profiles, and transverse emittance. The beam energy ranges from 300 keV/u to 10 MeV/u and beam intensities are between 1 pA and 1 nA. Faraday cups will be used for the measurement of the beam intensity while silicon detectors will be used for the energy and longitudinal profile measurements. The transverse profiles will be measured by moving a V-shaped slit in front of a Faraday cup and the beam position will be calculated from the profiles. The transverse emittance can be measured using the existing REX-ISOLDE slit and grid system, or by the combined use of two scanning slits and a Faraday cup. The final design of the mentioned devices will be presented in this contribution, including the results of the experimental validation tests performed on prototypes during the last two years.
