Ion Irradiation Facility - S

Categories: Ion beam facilities

Manufacturer: DREEBIT GmbH

Description

The IIF-S is the most compact one of DREEBIT's standard ion irradiation facilities. It can be equipped with Dresden EBIS/T ion sources providing various ion types from low-charged ions or molecule fragments up to highly charged ions. Depending on the ion source operation mode, continuous ion beams or ion pulses are transported through the beamline using ion optical elements (Einzel lenses, deflector elements) and ion beam diagnostics (Faraday cups). Ion species separation is realized by a Wien filter. The complete ion beamline, the ion source, as well as the target chamber are all designed for ultra high vacuum operation. A command and control system is delivered to operate the IIF-S via computer and automatically analyze the produced spectrum of ions.

The following table gives an overview of typical ion output values of the facility equipped with a Dresden EBIS-A. The values depend on the chosen source parameters which were optimized for each individual charge state in the given table. Higher and lower ion outputs are possible if another ion source is chosen. The values were recorded before deceleration into the target chamber.
