Combination of an Electron Spectrometer with an Ion Trap: first results for H- + hv and H- + H
Original language description
A new instrument is under development which is able to guide and store anions and to detect simultaneously electrons using the superposition of suitable RF and magnetic fields. It is based on a modular design combining (i) an rf storage ion source with mass spectrometer, (ii) an octopole ion guide or alternatively a temperature variable 22PT (iii) an electron spectrometer based on magnetic adiabatic collimation, and (iv) a channeltron electron multiplier (CEM) detector. All modules are transparent in axial direction and, therefore, the ions can be exposed to a beam of photons or of neutrals, e.g. also an H-atom beam. This allows us to study photo detachment of electrons from trapped anions and the interaction of anions with neutrals. A first successfultest has been the observation of the decay time of an H- ensemble exposed to a 532 nm laser. At laser powers of a few mW, storage times are a few s in accordance with the known detachment cross section. Similar loss rates have been measu
