 Dresden EBIS |
 Dresden EBIS-A |
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).

Dresden EBIS SC |
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
