As reported on the EFTF 2011, we trapped our first clouds of 40Ca ions in the new Titanium-Sapphire trap of the iQLOC experiment. This represents an important step towards realizing the first European Al+ quantum logic clock.

The pictures show the first cloud of ions observed in the system, the ion...
