Highly charged ions in magnetic fusion plasmas: research opportunities and diagnostic necessities

Spectroscopy Of Highly Charged Tungsten Relevant To Fusion Plasmas

The radiation emitted from highly charged tungsten ions has been measured at the Berlin Electron Beam Ion trap using high-resolution x-ray and EUV spectrometers. Highly charged tungsten ions ranging from Pm-like W to N-like W have been produced and excited in EBIT. The line emission originating from electric and magnetic dipole transitions is studied in a wide wavelength range from 0.12 to 80 n...

Parity Violation effects in highly-charged ions

Parity-nonconserving (PNC) atomic effects originate from the electroweak interaction of atomic electrons with the nucleus via Z-boson exchange. Comparing experimental results with theoretical predictions of the standard model allows to search for ”new physics” beyond the standard model (e.g., a second Z-boson or new fermions) [1]. In the case of neutral atoms here is the discrepancy between the...

Atomic Parity-Violation in Highly-Charged Ions

The investigation of parity-violation (PV) in forbidden atomic transitions is an active and fundamental research area, especially for its implications on the physics beyond the Standard Model [1]. Atomic transitions may be employed to study PV effects originating from weak neutral currents, i.e. due to the exchange of a Z boson between a nucleon of the nucleus and a bound electron. Experiments ...

Radioactive decays of highly-charged ions

Radiobiological Effects of Highly Charged Ions

The radiobiological effects of highly-charged-ion beams are of interest for tumortherapy and for radioprotection in space. In tumor therapy, high-energy protons and carbon ions exhibit an inverse dose profile, i.e. an increase of energy deposition with penetration depth. This allows a greater tumor dose for protons and carbon ions than for photons. In addition, for the heavier carbon ions, this...
