Investigations of fast ion-atom collisions in a storage ring, applying an ultra-cold supersonic gas-jet target

Objective



Research objectives and content
The main objective of the present proposal is the investigation of fast ion-atom collision experiments applying the internal ultracold gas-jet target at the heavy-ion storage ring 'CRYRING'. The technique to be used for extracting the detailed kinematics of the collision processes will be the novel technique recoil momentum spectroscopy (RIMS). By installing a gas-jet target and RIMS-spectrometer at the 'CRYRING' we obtain a unique combination of high ion beam quality and current and the cold highdensity target. This will allow us to extend the detailed studies of higher-order collision processes to higher energies, where the reaction cross sections are smaller.
Besides the main project I will be involved in lifetime measurements of the 1s2s 3s metastable state of He-like ions and investigation of multi-electron transfer processes slow collisions between highly charged ions and C60.
Training content (objective, benefit and expected impact)
From a basic science point of view I will gather experience in the field of ion-atom collisions, which is related to the electron ion collisions that I have investigated so far. Another aspect is of a technical nature: After working with electron coolers and an ebis storage-ring injector, the gas-jet target represents another storage-ring device for me to get acquainted with.
