Ions are from medicine, technology and basic research no longer be ignored. Especially promising for future-oriented technologies is the use of uploaded, because they have high neutralization energies involved in the interaction with solid surfaces in extremely short times and at realizing high energy densities in areas nanometer implemented.

To successfully uploaded ions to be able to apply, in which production is cheap and stable working sources. This was the science is not yet in the position.

With the development of ion sources of the "Dresden EBIT" - type (Dresden Electron Beam Ion Trap) succeeded Dresdner physicists here is the decisive breakthrough.

A working group headed by Dr. Guenter Zschornack from the Institute of Applied Physics of the Technical University of Dresden and the DREEBIT GmBH Dresden jointly developed this novel ion sources.

With a length of 30 cm and a weight of 10 kilograms, they present the Frankfurt fair audience is a very compact ion source. Especially scores the "New" with its spectacular interior life.

"We waive near absolute zero working superconducting magnets for formation of the electron beam. Rather, we pressed in the case of ions trapped electron beam with magnetic fields at room temperature to extremely high densities, together with a limited and that the electron beam then those atoms, in the beam is introduced and then stored in an electrostatic trap caught wrests.

The electron beam of atomic shell electrons, creating positively charged ions. this will be through an electrical field from the electron beam is extracted and fed different applications."
