Negatively charged ions are mainly stabilized through the electron correlation effect. A measure of their stability is their binding energy which is termed the electron affinity (EA). This fundamental quantity is, due to the almost general lack of bound excited states, the only atomic property that can be determined with high accuracy for negative ions. Together with the ionization potential...
For the past 60 years, the ISOLDE facility has delivered beams of high intensity and quality to the community worldwide. To keep a leading role in the development of ISOL beam production, beams and target developments are constantly done to reach new types of isotopes, yet unmet intensities or purity grades. These developments are done in various fields such as material science, ion source and...
Among the different types of target, use of the neutron converter type has resulted in increased dynamic electrical load seen by the actual 60 kV extraction voltage modulator, with the consequence that the recovery time of the target voltage to the precision of 0.001% is delayed, which in turn reduce the possibilities for the detection of exotic isotopes with extremely short half-lives. This...
Highlights of the 2016 on-line period will be presented, together with the latest results from the continuous RILIS R&D undertaken at ISOLDE. Expanding RILIS capabilities increase the possibility for customized (experiment specific) operation.
The RILIS was requested for >75% of ISOLDE experiments in 2016. There have been a number highlights from the RILIS perspective. On the experimental...
