\caption{Extrapolated gain values for $I > 750 \mu A$, using Ar/CO\subscript{2} $70/30$}
\label{ext-gain}
\end{table}

During the test beam we worked at gain values higher than those S. D. Pinto found, presented in \chaptername~\vref{ch-gainc}. \tablename~\vref{ext-gain} shows the extrapolated gain values for our working points (with Ar/CO\subscript{2} $70/30$), using Pinto's exponential fit of his X-Rays gain curve:
$$
G = 2 \cdot 10^{-6} \; e^{0.026 \cdot I}
$$

The expected current values refer to both the detector sides; actually, the two sides presented slightly different amperage due to small differences between the two divider circuits, in the range of $I_{left} = \left( I_{right} + \xi \right) \mu A$, where $0 \leq \xi \leq 4.3$.\\

The gas mixture inside the detector was Ar/CO\subscript{2} in 70/30 proportions, where not specified otherwise.\\
