This thesis investigates ion-molecule reaction studies with the use of an apparatus with a cryogenic 22-pole RF ion trap. In the introduction, we explain the suitability of an ion trap technique for measurements with conditions replicating interstellar medium. We created a technical draft by which we propose an upgrade of ion optics in a region between a mass analyser and a detector. The draft consists of a set of electrostatic electrodes. The proper effect on the ion optics was theoretically tested by multiple simulations in a programmed model of the detection system. We installed the set of electrodes into the apparatus. The new configuration was optimized by using an algorithm for finding extremes of a function. Finally, we tested the upgraded apparatus on a study of an ion- molecule reaction. The new configuration shows stability and greater control over the trajectory of an ion beam. The study's results are being prepared for publication in an impacted journal. 1
