Abstract
The invention relates to an ion surface trap (10) with an electrode pair (12) that comprises a first trap electrode (14.1) and a second trap electrode (14.2) and is configured to form a trap volume for at least one ion when an electrical AC voltage is applied, and a sensor element (18) for detecting photons (20) emitted by at least one ion, wherein the sensor element (18) comprises a superconductor layer and forms the second trap electrode (14.2) and does not have a superconductor layer-separating layer-superconductor layer structure.
Claims11
An ion surface trap, comprising:
- (a) an electrode pair that comprises a first trap electrode and a second trap electrode, wherein the electrode pair is configured to form a trap volume for at least one ion when an electrical alternating current voltage is applied,
- (b) a sensor element for detecting photons emitted by the at least one ion, and
- (c) wherein the sensor element comprises a superconductor layer and forms the second trap electrode of the electrode pair, and wherein the sensor element and does not have a superconductor layer-separating layer-superconductor layer structure.
The method according to claim 10, further comprising
- (i) vaporizing a pure substance so that it is available as a gas,
- (ii) photon-ionizing the gas, and
- (iii) moving at least one ion of the gas into a trap volume of the ion surface trap.
