Sven-Erik Ferm

Tekniker at Onsala Space Observatory

Sven-Erik has worked at Chalmers since 1995 and manufactures most of the details that the researchers at GARD use in their research. He uses CNC-controlled milling machines and lathes since there are small details which requires much accuracy in measurement to be made.
