As part of our involvement in the EU MICROTRAP project, we have designed, manufactured and assembled a micro-scale ion trap with integrated optical fibers. These prealigned fibers will allow delivering cooling laser light to single ions. Therefore, such a trap will not require any direct optical access for laser cooling. All the parts for the trap have been made in our institute . The electrodes and the spacers were laser cut in the collaboration with the group of P. Balling. In our group we have developed a technique to manufacture lensed optical fibers. The trap is now assembled and installed in an ultra high vacuum chamber, which includes an ablation oven for all-optical loading of the trap . The next steps on the project are to demonstrate the operation of the micro-trap and the cooling of ions using fiber delivered light.  D.
