 \subsection{Temperature range}
-Some, but not all, ion trap experiments are done in a cryostat, in particular to reduce ion heating rates and improve vacuum\cite{cryo} (in terms of both pumping speed and ultimate pressure achieved). To address a wider range of ion trap experiments, it is desirable that the device be operable at low temperatures (3 to 10K) as well as room temperature.

 \subsection{Vacuum}
 The device must be operable in a ultra-high vacuum environment. It must not outgas and must have a sufficient means of dissipating the heat it generates, such as being mounted to the wall of the vacuum chamber acting as heatsink.
