One might think that building cranes are an integral part of the Beutenberg Campus in Jena. Currently, one those cranes is located at the construction site of the building expansion of the Institute of Photonic Technology (IPHT) clean room. “Science is booming at this location. It requires space and the appropriate infrastructure,” says Prof. Jürgen Popp, scientific director at IPHT, of the continual construction. Today, Wednesday, May 19, 2010, several guests of honor, construction workers, and Institute employees celebrated the roofing ceremony.
