Experimental evidence on photo-assisted O $^{-}$ ion production from Al $_{2}$ O $_{3}$ cathode in cesium sputter negative ion source

O. Tarvainen, R. Kronholm, M. Laitinen +8

The production of negative ions in cesium sputter ion sources is generally considered to be a pure surface process. It has been recently proposed that ion pair production could exp…

Ti alloyed $α$ -Ga $_{2}$ O $_{3}$ : route towards wide band gap engineering

A. Barthel, J. W. Roberts, M. Napari +6

The suitability of Ti as a band gap modifier for $α$ -Ga $_{2}$ O $_{3}$ was investigated, taking advantage of the isostructural α-phases and high band gap difference between Ti $_{2}$ O $_{3}$ a…

Characterization of $^{233}$ U alpha recoil sources for $^{229 (m)}$ Th beam production

I. Pohjalainen, I. D. Moore, T. Sajavaara

Radioactive $^{233}$ U alpha recoil sources are being considered for the production of a thorium ion source to study the low-energy isomer in $^{229}$ Th with high-resolution colline…
