Electronics workshop

The IKP electronics workshop designs and constructs electronics for nuclear physics experiments. This includes

  • Construction of prototypes.
  • Small series production in cooperation with external service providers.
  • Maintenance, repair and modernization of existing electronic equipment.
  • Advice and technical support for the individual research groups and the institute management in the areas of data acquisition, tandem electronics and practical training.
