Description
C$_2^-$ and other anionic molecules are produced with an electric discharge valve and accelerated to 1.8 keV in a pulsed electric field. The C$_2^-$ are then mass selected in a Wien filter. Subsequently the C$_2^-$ are decelerated in the static electric field of a resistive tube with a potential difference of 1.798 kV to reduce the energy of the particles to a trappable range. A digital RF trap on the same potential stores the C$_2^-$ molecules before they are detected on a MCP.
This apparatus is suitable to test subsequent laser cooling of C$_2^-$. A successful cooling of anionic C$_2^-$ would open up novel experiments based on the sympathetic cooling of antiprotons and other anionic systems to sub-Kelvin temperatures.
