Ion surface trap, and method for operating an ion surface trap

An ion surface trap, comprising:

• (a) an electrode pair that comprises
• a first trap electrode,
• a second trap electrode, and
• wherein the electrode pair is configured to form a trap volume for at least one ion when an electrical AC voltage is applied,
• (b) at least two DC voltage electrodes arranged to close the trap volume and/or generate an electrical field, wherein when the trap volume is closed and/or the electrical field is generated an ion position of an ion trapped in the ion surface trap is modifiable relative to the ion surface trap, and
• (c) a sensor for detecting photons emitted by the at least one ion, wherein
• (d) the sensor is an energy-sensitive measuring superconductor sensor which has a first superconductor layer/separating layer/second superconductor layer structure, and
• (e) at least the first super conductor layer or at least the second super conductor layer in the first superconductor layer/separating layer/second superconductor layer structure forms the first trap electrode.
