\section{Standard Coincidence}  \label{sec:standardctr}  To begin standard coincidence measurements are made of Proteus LYSO:Ce scintillator crystals with a cross section of $2\times2$mm$^2$ wrapped in PTFE tape for lengths 5, 10, 15, 20 and 30mm. Two crystals of each length are measured opposite one another. The CTR is then determined as the FWHM of the delay distribution directly. In figure \ref{fig:standardctr} we see the expected degradation of the CTR with increasing crystal length \cite{r_Paganoni_Pauwels_et_al__2011}\cite{Wiener_Kaul_Surti_Karp_2010}\cite{Choong_2009}\cite{Gola_Piemonte_Tarolli_2013}\cite{o_Pro_Serra_Tarolli_Zorzi_2011}. The full set of results in given in table \ref{tab:standardctr}.
