+During R2013, there were data collected for both silicon and aluminium
+targets with the aluminium data being most useful for COMET and Mu2e
+and the silicon data being collected so that a cross check with the
+existing silicon data~\cite{sobo68} could be performed.
+
+For both materials, two different target thicknesses were used.
+For silicon, a thick, active target of 1500 \textmu m thickness was used with
+three different beam momenta to investigate muons stopping on the surface of
+the target and muons stopping closer to the centre. In addition, a thin,
+passive silicon target of 62 \textmu m was used.
+
+For aluminium, there were two different target thicknesses:
+100 \textmu m and 50 \textmu m with the muon beam momentum tuned so that the
+muon beam stopped towards the centre of the target.
+
+Table~\ref{tab:alcap:datasets} summarises the datasets and gives the
+muon beam momentum as a scale factor and the total number of muons
+as entering the experiment as counted by the $\mu$Sc beam scintillator counter.

+For all datasets, the aim was to measure the proton emission spectrum and normalise to the number of stopped muons by analysing the X-ray spectrum. In addition, preliminary investigations were made into the gamma ray and neutron emission spectra in preparation for a future run.
