Serianni G, et al. Rev Sci Instrum. 2022 Aug 1;93(8):081101. doi: 10.1063/5.0084797. Rev Sci Instrum. 2022. PMID: 36050050
As the single-beamlet optics defines the transmission losses along the beamline, the extraction of a similar current for all beamlets is extremely desirable, in order to facilitate the beam source operation (i.e., around perveance match). This Review investigates the corre …

Beam transport and space charge compensation strategies (invited).
Meusel O, Droba M, Noll D, Schulte K, Schneider PP, Wiesner C. Meusel O, et al. Rev Sci Instrum. 2016 Feb;87(2):02B937. doi: 10.1063/1.4939823. Rev Sci Instrum. 2016. PMID: 26932109
The transport of intense ion beams is affected by the collective behavior of this kind of multi-particle and multi-species system. The space charge expressed by the generalized perveance dominates the dynamical process of thermalisation, which leads to emittance growth. .. …

Patton T, et al. Sensors (Basel). 2023 Jul 7;23(13):6211. doi: 10.3390/s23136211. Sensors (Basel). 2023. PMID: 37448058 Free PMC article.
Stable and uniform beams with low divergence are required in particle accelerators; therefore, beyond the accelerated current, measuring the beam current spatial uniformity and stability over time is necessary to assess the beam performance, since these parameters affect the p …

A high intensity H₂⁺ multicusp ion source for the isotope decay-at-rest experiment, IsoDAR.
Axani S, Winklehner D, Alonso J, Conrad JM. Axani S, et al. Rev Sci Instrum. 2016 Feb;87(2):02B704. doi: 10.1063/1.4932395. Rev Sci Instrum. 2016. PMID: 26932067
By using a source in which the usual H(-) ions are replaced with the more tightly bound H2(+) ions, we can negate the effects of Lorentz stripping in a cyclotron, reduce the overall perveance due to the space-charge effect, and deliver twice the number of protons per nucle …
