\begin{frame}{Trigger firmware and logic}
    \begin{itemize}
        \item Trigger firmware is being modified to accomodate $5 \times 32 = 160$ input channels, up from $3 \times 32 = 96$
            \begin{itemize}
                \item FPGA utilization is not expected to be a problem but the channel addressing needs to be tweaked
                \item Corresponding changes are needed in the control software
            \end{itemize}
        \item Planned: Monte Carlo studies to develop the trigger logic, benchtop tests of the new firmware
    \end{itemize}
\end{frame}

\begin{frame}{SiPM readout}
    \begin{itemize}
        \item Preamp prototype has already been tested at Fermilab; first 20 of full production are now in hand and ready for QA
        \item SiPM-preamp pigtails will be prototyped soon, then the full frontend (SiPM+preamp+readout cable) can be tested for S/N, time resolution, and crosstalk
        \item Ferrite inductor saturation in the fringe field is a concern; testing is planned, and nonmagnetic inductors can be substituted
    \end{itemize}

%\begin{columns}
%\column{0.6\textwidth}
%\begin{itemize}
            %\item The resolution of the reconstructed mass should be independent of Z but is worse for displaced vertices.
            %\item This ad-hoc correction works pretty well: corrM = uncM - 0.15e-3*(elePX/eleP-posPX/posP)*uncVZ/uncM
            %\item Hunch: the vertex mass is being calculated using the track directions at $z=0$, or something like that.
