Radiofrequency traps are well recognized for their ability to co-trap
charged particles with different mass-to-charge ratios, such as different
ion species, even atomic and molecular ones, or ions with charged
nanoparticles [1]. At the AntiMatter-On-a-Chip project we currently
work on cotrapping electrons and ions. In this report we present results
on trapping electrons and Ca+ ions with a trap similar to the one
described in [2]. Trapping of electrons is achieved by applying 1.6
GHz to the resonator while trapping Ca+ ions is achieved by applying
2 MHz to DC electrodes. The influence of dual-frequency operation on
trapping stability and the lifetime of trapped particles were studied.
