\section{\textbf{Primary Beam}}  374 MeV $^{34}$S$^{8+}$ through 5 mg/cm$^2$ Be production target leaves 9.7(2) MeV/u $^{34}$S with a the charge state distribution below.  \begin{table}   \begin{tabular}{ c c }  Charge State & Fraction (\%) \\   16 & 73.5 \\   15 & 25.5 \\   14 & 1 \\   13 & 0.01 \\   12 & 6e-5 \\   \end{tabular}   \caption{374 MeV $^{34}$S through 5 mg/cm$^2$ Be production target.}   \end{table}  \textbf{Note from Bob Scott on the $^{34}$S charge state:} \textit{From: Scott, Robert H. The peak c.s. for $^{34}$S is 8+, you get about 1/3 peak output for 10+, 11+ output is reduced from 10+ to 1/3.}  \textbf{My reply to Matt Hendricks on minimum energy:} \textit{Acceptable Low-Energy for 34S: 374 MeV (11 MeV/u).} \textit{Acceptable beam current limit: >250 particle nano-Amps (> 2 euA for 34S8+ I believe)}. 

\textbf{Bob Scott purchased enriched material:}\textit{ 99.5\% 34S for \$4.8/mg. I have a quote for 400mg at a total of \$1944.00 USD}.
