COmbustion- and Re-Entry-PLasma research Using the ion Storage facility DESIREE (COREPLUS)
Abstract
This project exploits the world-wide unique capability of the Stockholm University, Double ElectroStatic Ion Ring ExpEriment (DESIREE). This purely electrostatic storage facility enables the study of interactions between cations and anions at low and well-defined internal temperatures and centre-of-mass collision energies down to about 10 K and 10 meV, respectively with control over the reaction environment (temperature: ~10 K to 300 K) and the reaction collision energy (0.01 eV to 100s eV). This facility enabled initial investigations into neutralizing reactions relevant to: (1) Air-plasmas related to both laser-ignition and plasma-assisted combustion and (2) Plasmas generated around re-entrant space vehicles. Position sensitive multi-hit detector systems which have been extensively tested and proven to work in cryogenic environments was used in coincidence to measure correlations between reaction products in, for example, electron-transfer processes. Control over the reaction environment and the reaction collision energy means that any desired information, for examples: reaction cross-sections and fragment populations can be obtained over all conditions needed to accurately model these processes. Towards the end of this effort, C+ cations and C- anions have been simultaneously injected into the asymmetric and symmetric rings, respectively, and stored for several 10s of seconds.
