First storage of ion beams in the Double Electrostatic Ion-Ring Experiment: DESIREE.
We report on the first storage of ion beams in the Double ElectroStatic Ion Ring ExpEriment, DESIREE, at Stockholm University. We have produced beams of atomic carbon anions and small carbon anion molecules (C(n)(-), n = 1, 2, 3, 4) in a sputter ion source. The ion beams were accelerated to 10 keV kinetic energy and stored in an electrostatic ion storage ring enclosed in a vacuum chamber at 13 ...
متن کاملAstrophysical Relevance of Storage-Ring Electron-Ion Recombination Experiments
The relevance of storage-ring electron-ion recombination experiments for astrophysics is outlined. In particular, the role of low-energy dielectronic-recombination resonances is discussed. A bibliographic compilation of electron-ion recombination measurements with cosmically abundant ions is provided.
متن کاملTime evolution of internal energy distribution of Anthracene studied in an electrostatic storage ring, the Mini-Ring
Fast radiative cooling of polycyclic aromatic hydrocarbon (PAH) was studied by probing the time evolution of the internal energy distribution of hot molecular ensembles in the ms range. Anthracene cations (C14H10) prepared in an electron cyclotron resonance ion source were stored in an electrostatic storage ring, the Mini-Ring [1]. The experiment showed that in the first milliseconds, the time ...
متن کاملDesign Studies of an Electrostatic Storage Ring
Electrostatic storage rings combine a number of very interesting characteristics that make them an attractive tool in the low energy range. In contrast to magnetic rings, all of the fields in an electrostatic storage ring are completely mass independent. At the same particle energy and charge state, ions from light protons to heavy biomolecules can in principal be stored with identical field se...
متن کاملAstrochemistry in an Ion Storage Ring
Storage ring studies of low energy electron collisions with molecular ions have been carried out for dissociative recombination (DR) of fluorine-bearing molecules. Here we report on work aiming to improve the understanding of astrochemistry involving HF, a possible spectroscopic tracer of interstellar H2. For CF + the rate coefficient was obtained for temperatures down to 10 K. For D2F + the DR...
