A compact, versatile low-energy electron beam ion source

Area of Science:

• Atomic Physics
• Plasma Physics
• Accelerator Technology

Background:

• Electron Beam Ion Sources (EBIS) are crucial for producing ions.
• Existing EBIS often operate at higher electron beam energies.
• There is a need for compact ion sources optimized for low-energy operation.

Purpose of the Study:

• Introduce the Dresden EBIT-LE, a novel compact Electron Beam Ion Source.
• Characterize its performance at low electron beam energies (100 eV to a few keV).
• Demonstrate its potential for ion production and X-ray generation.

Main Methods:

• Design and construction of the compact Dresden EBIT-LE.
• Operation at variable electron beam energies from low keV to 15 keV.
• Ion extraction experiments and X-ray spectroscopy measurements.

Main Results:

• Stable production of low and intermediate charged ions demonstrated below 2 keV electron beam energy.
• Achieved electron beam currents up to a few mA at low energies and ~40 mA at higher energies.
• Confirmed utility as an X-ray source from ions excited at low electron energies.

Conclusions:

• The Dresden EBIT-LE is a versatile and compact ion source suitable for low-energy applications.
• It offers stable ion production and can be adapted for higher energy regimes.
• The device shows promise for both ion generation and X-ray spectroscopy research.
