Development of a Lab-prototype CI-TOF Instrument for the Airborne Detection of Ultra-trace Gases in the UTLS

Abstract:
We have developed a new transfer stage for an airborne CI-TOF instrument aiming for high sensitivity and a soft ion transfer, which are in contrast to each other.
A combination of two ion funnels working at 100 and 5 hPa and two quadrupoles has been modeled, built and tested.
In addition, we are developing a DBD ion source as a replacement for the standard radioactive source.
First results on the transmission efficiency and ion chemistry in the transfer stage will be discussed in comparison with results of fluid-dynamical and electro-dynamical simulations.
