International audience; For the Facility for Antiproton and Ion Research (FAIR) a compact proton linac will produce proton beams with energy of 68 MeV that will be injected into upgraded Heavy Ion Synchrotron (SIS 18), accelerated to 4 GeV, and further accelerated to 30 GeV in SIS 100. The commissioning of the proton injector which would serve for the injection into the proton linac has already started at CEA/Saclay. The ion source operating with a microwave frequency of 2.45 GHz based on Electron Cyclotron Resonance (ECR) plasma production with two coils each with 87.5 mT magnetic field, will deliver a 100 mA proton beam at 95 keV of energy. The Low Energy Beam Transport (LEBT) including two short solenoids system and integrated steerers will transport the proton beam to the RFQ entrance with an expected emittance lower than 0.3π mm mrad (normalized, rms). After the LEBT an electrostatic chopper will be mounted in front of RFQ to shorten the beam pulse to 36 µs. This paper presents the status of the commissioning phases including first results of proton injector.

In 2012 the CRYRING storage ring was delivered from Stockholm to Darmstadt as a part of the Swedish in-kind contribution to the FAIR project. The ring lattice has been slightly changed for optimal injection and to provide additional space for experiment equipment. For the injection from the experimental storage ring (ESR), a new transfer line has been designed. The local injector line has been significantly modified compared to the previous one in Stockholm taking into account the geometry of the existing GSI building. In this paper we present the ion-optical properties of CRYRING@ESR after the described modifications. Single-turn injection from the ESR and multi-turn injection from the local injector are discussed. Ion-optical calculations of fast and slow extraction from CRYRING are also presented. The closed orbit correction scheme is considered taking into account the future arrangement of the beam position monitors and correction magnets. Based on the results of the calculations the requirements for the magnet alignment are finally discussed.

We report on the resonant coherent excitation (RCE) of the 2s-2p3/2 transition in Li-like U89+ with an enhanced energy resolution, which was achieved by reducing the projectiles momentum spread. The kinetic temperature of the beam was decreased by electron cooling in the ESR, and the collisional momentum broadening in the target was suppressed by the use of thin crystal (1.0 and 2.5 μm-thick). The resonance width was observed to be ~1.4 eV in FWHM, which is three-times narrower than that from the previous work.
