Determination of the extraction efficiency for ${}^{233}$U source $\alpha$-recoil ions from the MLL buffer-gas stopping cell

Lars von der Wense, Benedict Seiferle, Mustapha Laatiaoui +1

Following the $\alpha$ decay of ${}^{233}$U, ${}^{229}$Th recoil ions are shown to be extracted in a significant amount from the MLL buffer-gas stopping cell. The produced recoil ions and s…
