1. An ion-trap enclosure comprising:
a first chamber that contains an ion trap;
a second chamber;
a first conduit that fluidically couples the first and second chambers;
a source that is located in the second chamber, the source being configured to provide an atomic flux to the ion trap through the first conduit such that the atomic flux predominantly includes neutral atoms of a first material; and
a first optical source configured to provide a first light signal to the ion trap, wherein the first light signal is operative for photo-ionizing one or more neutral atoms of the atomic flux at the ion trap; wherein:
a flow path between the first chamber and the second chamber, as provided by the first conduit, is at all times unimpeded, and
a physical separation between the first and second chambers substantially reduces a transfer of heat, which heat results from the generation of the atomic flux, from the second chamber to the first chamber.
 
12. A method for trapping at least one ion in an ion trap, the method comprising:
providing an atomic flux to the ion trap, wherein the atomic flux predominantly includes neutral atoms of a first material, and wherein the ion trap is located in a first chamber and the atomic flux is generated in a second chamber that is fluidically coupled with the first chamber via a first conduit, wherein a flow path between the first chamber and the second chamber, as provided by the first conduit, is at all times unimpeded, and further wherein a physical separation between the first and second chambers substantially reduces a transfer of heat, which heat results from the generation of the atomic flux, from the second chamber to the first chamber; and
photo-ionizing at least one neutral atom of the atomic flux at the ion trap.
