  • Three generations of the room-temperature EBIT/EBIS (Electron Beam Ion Trap/Source) type, the Dresden EBIT, Dresden EBIS, and Dresden EBIS-A are available.

  • The Dresden EBIT/EBIS supplys bare ions for elements with an atomic number of up to 28, helium-like ions for ions such as krypton and neon-like ions for high-Z elements.

  • The design of the ion sources is based on permanent magnets resulting in a very compact design. Thus, it is portable, simple to operate, and both initial and maintenance costs are negligible.

  • The vacuum system is based on standard UHV techniques that allows trap operation at pressures in the range of up to
    10-10 mbar. Working gases are admitted through precision leak valves.

  • The produced ions can be extracted in both pulse mode (pulse width from 2 µs up to 40 µs) and leaky mode (DC mode). In addition, the ion sources feature a very small emittance of the ion beam which is in the order of less than 10 mm mrad.

  • High-current low-emittance beams of low charged particles such as protons, alpha particles, and molecular fragments are provided in DC mode.

  • Since the electron energy can be adjusted the Dresden EBIT/EBIS are excellent sources of specific electromagnetic radiation such as x-rays, ultraviolett, EUV and visible light.

  • The ion source supplies ions from gaseous elements and metals in a wide range of both the ion charge state and their kinetic energy (10 eV x q to 40 keV x q).

  • DREEBIT's latest release is a compact superconducting ion source, which is based on modern principles of low temperature physics and electron beam technology

  • It is capable of producing high and low charged ions of almost any element

  • Particle injection into the Dresden EBIS-SC can be realized by different injection methods such as gas inlet, volatile compounds, the use of a Liquid Metal Ion Source (LMIS), ovens and Metal Vapor Vacuum Arc Sources (MEVVA)

  • The source uses a high emissive cathode, generating a strong electron beam which is magnetically compressed to high electron beam densities

  • Pulsed ion beams and DC beams (leaky mode) can be generated

  • The length of the extracted ion pulses extends from some tens of µs up to 100 µs

  • The pulse form can be varied from Gaussian up to flat-top shapes
