Ion Sources

Welcome to the website of the ion source department at GSI. We are operating three injectors feeding the UNILAC with various types of ion species. Two of them are high current injectors, the third one is injecting high charge-states for further acceleration in the linear accelerator. For operation various types of ion sources are used.

The primary tasks for the FAIR project are:

  • Installation and startup of the FAIR proton injector
  • Creation of specifications, procuration, order tracking, approvals and startups, securing of the agreed quality and safety standards
  • Preparation and organization of the prospective FAIR accelerator operation

Further duties, responsibilities and projects:

  • Operation of the existing GSI injectors
  • Installation and startup of terminal west for high intense uranium ion beams
  • Safety-related responsibility and responsibility of the relevant machine and equipment parts
  • Planning and realization of shutdown measures for the existing injectors
  • Participation at planning and execution of the upgrade measures for the existing UNILAC to provide high intense heavy ion beams for the FAIR requirements (FAIR-UNILAC-Upgrade)
  • Participation at installation, startup and operation of a cw compatible injector to provide intense highly charged ions (HLI-Upgrade)
  • ECR ion sources of highest heavy ion intensities (28 GHz ECRIS)
  • Further development to provide the FAIR required ion source performance (gas- and metal Penning ion sources, high current ion sources and ECR ion sources)
