Description
C$_2^-$ and other anionic molecules produced in an electric discharge in an Even-Lavie valve are accelerated to 1.8 keV in a pulsed electric field; the C$_2^-$ is then mass selected in a Wien filter. Subsequent deceleration in the static electric field of a resistive tube with a potential difference of 1.8 kV reduces the energy of the particles to a trappable range. A digital RF trap on the same 1.8 kV potential stores the C$_2^-$ molecules for subsequent experimentation with cooling lasers. A successful cooling of anionic C$_2^-$ would open up novel experiments based on sympathetic cooling of antiprotons and other anionic systems to sub-Kelvin temperatures.
