“…Thanks to the RIB post-acceleration in the CIME cyclotron, a very high mass separation M/δM∼10000 is expected [8] granting an efficient cleaning of the N+ RIB signal, making it suitable for final RIB experiments. The SPES facility (LNL), under construction, is also equipped with a medium mass separator M/δM∼1000 [9]. With a RIB signal intensity of 10 6 /s and specific background reduction in the ECR CB, a clean N+ RIB signal is also expected.…”

A: Electron cyclotron resonance charge breeder (ECR CB) is one of the instruments used to boost the radioactive ion beam (RIB) charge state (from 1+ to N+) in isotope separator on-line (ISOL) facilities. While existing ECR CB can manage intense incoming 1+ RIB without difficulty, significant amounts of background impurities are extracted with the N+ RIB signal. When the N+ RIB signal is very low, the dominant background can be detrimental to the study of the RIB in today facilities, if no downstream high mass resolution separation is available. This work investigates the improvements achievable with a new generation 18 GHz ECR CB applicable to future facility like EURISOL. The study shows that with a modified ion source geometry, an optimized magnetic confinement, a careful wall metal choice like beryllium, a UHV technology, the charge breeder performance will improve as follows: +20% higher capture efficiency, −40% charge breeding time, charge state ion production with mass over charge of 3 up to xenon and over 6 up to uranium, co-extracted contaminant density reduction by a factor 60 to 600. An 18 GHz ECR CB ion source layout is finally proposed for EURISOL. K: Accelerator Applications; Instrumentation for radioactive beams (fragmentation devices; fragment and isotope, separators incl.

“…In these cases, emittance reflects the phase space necessary to decay and/or efficient production reactions, so transverse momentum is much larger, also exceeding the MeV/c range (Neuffer 1983;Boscolo, Delahaye & Palmer 2019), with corresponding larger sizes (over 100 m). As for the unstable nuclei (also called 'exotic'), in the example of the Selective Production of Exotic Species (SPES) (de Angelis et al 2015) project at the Laboratori Nazionali di Legnaro (LNL), a H + beam from a cyclotron induces fission reactions in a hot target, with products first stopped into the target, then diffusing and singly ionized in an ion source (Manzolaro et al 2014), labelled IS in figure 1(a).…”

“…Most of all, the beam extracted from the source may contain many different 'isobaric' ions (for example 100 Mo 1+ and 100 Tc 1+ ), which need to be separated before re-acceleration and delivery to experimental areas. In the SPES project, the envisioned high resolution mass spectrometer (HRMS) (de Angelis et al 2015) has a resolution goal 1:20 000. The HRMS design therefore requests a high voltage platform (HVP) to increase the ion kinetic energy to K i ∼ = 160 keV, and a normalized r.m.s.…”

Radio frequency quadrupole coolers (RFQCs) are very suitable to cool ion beams with moderate energy spread, typically ions of exotic nuclear species (like $^{132}$ Sn $^{1+}$ ) as in the Selective Production of Exotic Species project at the Laboratori Nazionali di Legnaro, whose ion source supplies 40 keV ions. Beam dynamics includes ion–gas collisions (with a balance of cooling and diffusion effects), acceleration and deceleration and radiofrequency confinement, which can be supplemented by static magnetic field effects. Insertion of a prototype RFQC in the solenoid of the Eltrap machine is also discussed here, with innovations in beam extraction and in modelling, now also based on stochastic equations. Practical consideration on gas pumping and voltage distribution are also included. Typical limits of RFQC are discussed, with special attention to the extracted beam root mean square emittance, which is shown to strongly depend not only on cooler parameters, but also on extraction optics.

Nucleon transfer reactions with radioactive beams

Transfer reactions are a valuable tool to study the single-particle structure of nuclei. At radioactive beam facilities transfer reactions have to be performed in inverse kinematics. This creates a number of experimental challenges, but it also has some advantages over normal kinematics measurements. An overview of the experimental and theoretical methods for transfer reactions, especially with radioactive beams, is presented. Recent experimental results and highlights on shell evolution in exotic nuclei are discussed.
