D− Charge Exchange Ionizer for the JINR Polarized Ion Source POLARIS

AIP Conference Proceedings, 2003
The spin physics program is an important part of the LHE JINR scientific program. An intensive study of polarization phenomena was carried out at the Dubna 4.5 Gev/nucl. synchrophasotron, using cryogenic source of polarized deuterons (↑D+) POLARIS. There is a proposal to make a polarized deuteron beam in the new accelerator Nuclotron to continue the ...

Role of electron impact multiple ionization and charge exchange in the ionization balance of tungsten ions in fusion plasmas

Plasma Physics and Controlled Fusion
Abstract Electron impact multiple ionization (EIMI) and charge exchange (CX) are two atomic processes that are often neglected in investigations of charge state distributions (CSDs). However, previous investigations have demonstrated that EIMI has a non-negligible effect on the dynamic equilibrium of iron ions ...

Ionization channel in non-perturbative ion-atom collisions dominated by charge exchange

AIP Conference Proceedings, 2001
The development of the described method has been motivated by studies of the proton-atomic oxygen collision system, where the accidental closeness of energy levels makes the charge exchange quasi-resonant. In slow collisions the ionization channel must compete with the resonant exchange channel.

A scheme for a polarized 3He ion source with a resonant charge-exchange plasma ionizer

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998
Abstract A scheme for a polarized 3He2+ ion source based on resonant charge-exchange between polarized 3He atoms and unpolarized 4He2+ ions is proposed. Polarized atoms in this scheme are produced by optical pumping with metastability exchange. The polarized atoms are stored then in a storage cell.
