“…4 A liquid nitrogen cooled storage ring was constructed at the Tokyo Metropolitan University and has been in operation for a number of years. 5 A somewhat larger electrostatic storage ring with a very different ion-optical layout and which will be operated at room temperature 6 has been constructed at Frankfurt University. The Frankfurt ring is currently being commissioned as is a smaller 4 m circumference room temperature ring at Aarhus University.…”

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 K. For 10 keV C − 2 molecular anions we measure the residual-gas limited beam storage lifetime to be 448 s ± 18 s with two independent detector systems. Using the measured storage lifetimes we estimate that the residual gas pressure is in the 10 −14 mbar range. When high current ion beams are injected, the number of stored particles does not follow a single exponential decay law as would be expected for stored particles lost solely due to electron detachment in collision with the residual-gas. Instead, we observe a faster initial decay rate, which we ascribe to the effect of the space charge of the ion beam on the storage capacity. © 2013 AIP Publishing LLC. [http://dx

“…These advantages were realised through the pioneering work of Søren Pape Møller in Aarhus, Denmark, with the construction of the purely electrostatic storage ring ELISA [5], and since ELISA was constructed several new electrostatic storage rings have been built or are under construction around the world, for examples in Japan [6,7], Frankfurt [9], Saudi Arabia [8]. It is noted here that one of the rings constructed in Japan [7] is cooled down to liquid nitrogen temperatures and operates under these cyrogenic conditions.…”

Abstract. Here we will briefly describe the commissioning of the Double ElectroStatic Ion Ring ExpEriment (DESIREE) facility at Stockholm University, Sweden. This device uses purely electrostatic focussing and deflection elements and allows ion beams of opposite charge to be confined under extreme high vacuum and cryogenic conditions in separate "rings" and then merged over a common straight section. This apparatus allows for studies of interactions between cations and anions at very low and well-defined centre-of-mass energies (down to a few meV) and at very low internal temperatures (down to a few K).

“…It started operation in 1998 and has stored many different ion species during the last decade [9,10]. Two storage rings with a similar lattice were built in Japan at Tokyo Metropolitan University and at KEK [11,12]. All three rings operate at a fixed energy of up to 25 keV .…”

Low Energy Storage Rings: Opening Routes for Beyond State-of-the-art Research

Electrostatic storage rings have proven to be invaluable tools for atomic and molecular physics at the ultra-low energy range from 1 to 100 keV/A. Due to the mass independence of the electrostatic rigidity these machines are able to store a wide range of different particles, from light ions to heavy singly charged bio-molecules. Their beam dynamics is, however, fundamentally different to magnetic storage rings and therefore needs to be investigated in detail to optimize storage ring performance and experimental output. This paper first gives an overview of existing electrostatic storage rings and their experimental programs. Second, future machines in Heidelberg, Stockholm and the Facility for Antiproton and Ion Research (FAIR) are described and the main challenges are summarized. Finally, the focus is set on a flexible storage ring facility presently being built up at the King Abdulaziz Center for Science and Technology (KACST) in Riyadh, Saudi Arabia, that addresses a broad user community and will allow for a next-generation experimental program in the low energy regime.
