Reducing ion-beam noise of vacuum arc ion sources

Temporal development of ion beam mean charge state in pulsed vacuum arc ion sources.

Vacuum arc ion sources, commonly also known as "Mevva" ion sources, are used to generate intense pulsed metal ion beams. It is known that the mean charge state of the ion beam lies between 1 and 4, depending on cathode material, arc current, arc pulse duration, presence or absence of magnetic field at the cathode, as well as background gas pressure. A characteristic of the vacuum arc ion beam i...

Ion energy distribution functions of vacuum arc plasmas

Electron beam ion sources and traps „invited..

The electron beam method of stepwise ionization to highest charge states has found applications in electron beam ion sources ~EBISs! for accelerators and atomic physics collision experiments as well as in electron beam ion traps ~EBITs! for x-ray and mass spectroscopy. A dense and almost monoenergetic electron beam provides a unique tool for ionization, because radiative recombination by slow e...

Intense Beam Ion Sources Development at Imp *

To satisfy the HIRFL (Heavy Ion Research Facility in Lanzhou) accelerators’ requirement and the needs of several other future accelerator facilities, many high beam intensity ion sources have been developed at IMP. The ion sources include intense high charge state ion beam ECR ion sources and high intensity proton beam ECR or microwave sources. This paper will review the high charge state ion s...

Electron Beam Ion Sources, Ion Optical Elements and Beam Diagnostics for Particle Accelerators

Electron Beam Ion Sources (EBISs) provide highly charged ions (HCIs) for a variety of investigations and applications, e.g. amongst others as injection source for particle accelerators. EBISs feature a lot of advantages which qualify them for accelerator injection, and which partly compensate for their comparatively low number of particles. DREEBIT GmbH provides a family of compact EBISs based ...
