Design and fabrication of a micro-ion trap with a 3D-printed loading zone for improved hot-ion capture

Sayan Patra, Abhinav Parakh, Xiaoxing Xia +3

We leverage recent advances in 3D-printing technology to design and fabricate a micro-ion trap with a spatially distinct loading zone for more efficient loading of ions from effusi…

Trapping of electrons and $^{40} Ca^{+}$ ions in a dual-frequency Paul trap

Vladimir Mikhailovskii, Natalija Sheth, Guofeng Qu +12

We demonstrate the operation of a dual-frequency Paul trap and characterize its performance by storing either electrons or calcium ions while applying two quadrupole fields simulta…
