Energy loss and cooling of relativistic highly charged uranium ions interacting with an internal hydrogen droplet target beam

Electron- and proton-impact excitation of heliumlike uranium in relativistic collisions

“…Owing to the development of a new multiphase target for the ESR [19,20] providing densities of up 10 15 particles/cm 2 , we were able to explore for the first time the EIE of H-like uranium [21]. Here, it is important to emphasize that EIE is a fundamental atomic process which plays a very prominent role in various kinds of laboratory and astrophysical plasmas.…”

Heavy-ion storage rings and their use in precision experiments with highly charged ions

“…Then, the calculations based on Hauser-Feschbach theory might be inadequate. This holds, for instance, for the case of the 33 Cl(p, γ) 34 Ar and 34 Cl(p, γ) 35 Ar reactions in O-Ne novae, where only several states are relevant. These reactions are needed to constrain the parameters for the S-Cl burning cycle and set the limits on the existence of the galactic 34m Cl γ-emitter.…”

“…The upper limit of the acceptable target density is either defined by the technical abilities to produce the highest densities or by the ability to compensate the energy loss and scattering of the beam particles by cooling and rf systems. Depending on the beam species and the beam energy, target densities exceeding 10 14 − 10 15 hydrogen atoms/cm 2 have been shown to exceed the capacity of the beam cooling system and result in fast beam loss [35].…”

Investigation of the nuclear matter distribution of 56Ni by elastic proton scattering in inverse kinematics

“…A good angular resolution for the detector telescope located close to 90°was maintained by using a slit aperture in front of the target. In the future, this will become obsolete thanks to reductions in the spatial extent of a new droplet target replacing the present gas-jet target, enabling an interaction zone with sizes smaller than 1 mm [26][27][28].…”
