Sigurd Hofmann. Portrait of Sigurd Hofmann, German particle physicist involved in the creation of new chemical elements. He is the leader of the Separa- tor for the Heavy Ion reaction Products (SHIP) programme at the Heavy Ion Research (GSI) centre at Darmstadt, Germany. GSI creates new elements by bombarding targets with a beam of fast heavy ions from the UNILAC accelerator. The SHIP detector uses magnetic fields to separate the reaction pro- ducts before they pass into a detector for identi- fication. The GSI laboratory discovered elements 107 to 112, the 6 heaviest-known, during 1981-96, an achievement largely due to improvements in the efficiency of the SHIP. Photographed in 1997.
