Thick-film technology for ultra high vacuum interfaces of micro-structured traps
We adopt thick-film technology to produce ultra high vacuum compatible
interfaces for electrical signals. These interfaces permit voltages of hundreds
of Volts and currents of several Amperes and allow for very compact vacuum
setups, useful in quantum optics in general, and especially for quantum
information and quantum simulations using miniaturized traps for ions or
neutral atoms. Such printed circuits can also be useful as pure in-vacuum
devices. We demonstrate a specific interface, which provides eleven current
feedthroughs, more than 70 dc feedthroughs and a feedthrough for radio
frequencies. We achieve a pressure in the low 1e-11mbar range and demonstrate
the full functionality of the interface by trapping chains of cold ytterbium
ions, which requires all of the signals mentioned above being present. In
addition, a versatile multi-channel device for supplying precise time-dependent
voltages has been developed.Comment: 8 pages, 7 figures added references to recent literature about
