Diamond Ion Traps
Diamond structures that carry electrodes to confine ions in vacuum.
Good to know
- Electrode geometry defines the trapping structure.
- Dimensional accuracy, dielectric behaviour and heat removal matter together.
- Conductive coatings and their separation must follow the trap design.
