Abstract
Abstract: In this paper, we describe an instrument and measurement technique which makes possible the determination of gas-phase ion/molecule reactions down to 10 K or lower and up to 20–100 K, depending on the species. The technique is particularly useful for the measurement of reaction rates between 10−11 and 10−15 cm3 s−1. The instrument makes use of a cooled hyperbolic Penning trap and a bolometric detector. We also describe the behavior of the stored ions and their interactions with the cryogenic neutral gases.
