\title{Preparing for the mock data challenge}

\author{Sho Uemura}

\begin{document}

\begin{frame}
	\titlepage
\end{frame}

\begin{frame}{Outputs}
	\begin{itemize}
		\item Mock data sets: 1 week of data each
			\begin{itemize}
				\item Primary generators limited to events that would pass a basic event filter: tridents with some trigger and kinematic cuts, plus secret signal
				\item Overlay 1 $\mu$s of beam background with each trident, run trigger and readout
			\end{itemize}
		\item Beam background sample: 1 million triggers
			\begin{itemize}
				\item Fully realistic --- run 1 minute of beam electrons through the target (EGS5 scattering, full-diagram tridents, hadrons) and detector, run trigger and readout
				\item Very resource-intensive, but needed to verify trigger and event filter
			\end{itemize}
	\end{itemize}
\end{frame}

\begin{frame}{Major steps, in order}
	\begin{itemize}
		\item Make beam background sample, run through SLIC
			\begin{itemize}
				\item This has to go first, to test the trigger and the event filters
			\end{itemize}
		\item Make trident and signal samples, run through SLIC
			\begin{itemize}
				\item This is the bulk of the batch processing --- a couple of months
			\end{itemize}
		\item Run readout, recon and DST; release the MDC 
	\end{itemize}
\end{frame}

\begin{frame}{Details}
	\begin{itemize}
		\item Primary generators (tridents, hadrons): Takashi
			\begin{itemize}
				\item MadGraph generators for BH and radiative tridents are ready to test
			\end{itemize}
		\item Detector geometry
			\begin{itemize}
				\item Deadline 11/11; what we have is good enough
			\end{itemize}
		\item Tune/test trigger on latest beam background: Kyle
			\begin{itemize}
				\item Disabling hot crystals seems adequate
			\end{itemize}
		\item Various production tasks: merging primary generator outputs, running the generators and simulations, keeping batch jobs and files organized
	\end{itemize}
\end{frame}

\begin{frame}{Boring production tasks}
	\begin{itemize}
		\item Oversampling EGS5 background
			\begin{itemize}
				\item Generate 5e5 bunches' worth of beam electron interactions and shuffle them into 5e7 bunches
			\end{itemize}
		\item SLIC installation and testing (2 tasks)
			\begin{itemize}
				\item Install latest ilcinstall release at JLab, getting it around the firewall
				\item We still have unexplained SLIC crashes/errors, must investigate
			\end{itemize}
		\item LHE->StdHep
			\begin{itemize}
				\item Tridents are fed into EGS5 to apply multiple scattering, EGS5 writes to StdHep file --- this works
				\item A' (even ``prompt'') decay after the target so they get converted directly to StdHep --- Matt has hps-java code for this, just need to make sure it does what I need
			\end{itemize}
		\item Batch job engineering
			\begin{itemize}
				\item We have the whole production chain (through recon) working for background+tridents; need more of the same for all the other stuff
				\item Production runs in units of 5e5 beam bunches; need to merge after readout so we don't have thousands of tiny files
			\end{itemize}
	\end{itemize}
\end{frame}
