Ion in the Four Rod Trap

The ion team has seen their first 174Yb ion in the new four rod trap. This linear trap consists of four 50 µm diameter wires which are spaced 350 µm from each other. The rods are held and separated by a fused silica piece which was fabricated by Translume in Ann Arbor. In the picture these fused silica pieces are attached to a monolithic stainless steel trap mount. In order from preventing the atoms escaping the trap two endcaps have been added to which we apply DC voltages. In the top right a microscope image of the fused silica piece is shown.
