Equipment for Analyses of Low and High Current Charged Particle Beams
From simple current measurements to imaging-based analyses for detailed investigations of beam properties - DREEBIT offers various tools for physicists and engineers working with charged particle beams which can easily be integrated into existing facilities.
Faraday Cup with 4 Additional Electrodes for Beam Positioning
This Faraday cup is used for broad, off-axis charged particle beams which need to be focused and deflected in the right direction. It consists of a central electrode and four surrounding outer electrodes indicating the beam size and position in relation to the beamline center.
The 4-Jaw Slit System is used for analyzing as well as forming the size and shape of a charged particle beam. It consists of four plates which can be moved individually from an out-of-beam position into the beam.
The Beam Imaging System (BIS) allows the user to detect and evaluate particle beam cross sections in real-time in a high vacuum or ultra high vacuum environment. It creates an image of the beam by converting the incident beam signal into visible light.
A Real-Time Beam Monitoring and Emittance Measurement System
The Pepperpot Emittance Meter allows to evaluate beam parameters of particles as well as x-rays in real-time. A pepperpot-like mask separates the beam into beamlets. With an image of the beamlets taken by a CCD camera, a phase space analysis can be carried out and the beam's emittance and twiss parameters can be calculated.
Energy Distribution Analysis of Charged Particle Beams
The Retarding Field Analyzer (RFA) is an electrostatic charged particle beam energy analyzer which allows for measuring the kinetic energy distribution and the energy spread of the particles up to a beam energy of 15 keV per charge state.
The Wien Filter is a charged particle separator with a crossed electric and magnetic field configuration (ExB). One ion species of interest with a specific velocity due to its mass-to-charge ratio passes the Wien Filter straightforward, all other species are deflected and absorbed between the Wien filter apertures.
A 90° Bending Magnet for High-Current Applications
The High-Current Analysis Magnet is a double focussing dipole magnet designed to bend ion beams by 90° for charge-to-mass ratio analysis of the ion beam components. The compact design is tailored for high-current medium-emittance beams such as mA currents from high-power electron cyclotron resonance (ECR) ion sources.
