+\textbf{Active silicon target 1.5~mm and 50~\textmu m, 4 days}. The R2015
+charged particle run will begin
+ with an Si active
+target, as this target is ideal for setting up the experiment. 
+The emission spectrum in a thick Si detector was measured in 2013 
+and compared to 
+the only low energy proton spectrum in the literature. However, the 
+measurement is partially compromised with FADC data losses and an 
+unoptimised fast signal
+chain. The emission spectrum in a new thin silicon detector will be 
+measured, to verify the overall measurement strategy, as the rate 
+and spectrum are known from the thick Si measurement. Moreover, the 
+active detector will allow the reconstruction of the response matrix.

+\textbf{Aluminium 50~\textmu m, 3 days}. This measurement should corroborate a key result of the charged particle measurement program
+under a  well defined condition. The statistics and improved signal to
+noise will 
+completely cover the emission spectrum. In particular, the shaping
+times of the fast signals
+will be optimised. This will allow the rejection of background events 
+due to muon stops with proton emission in
+the Si detectors.

+\item
+\textbf{Titanium 100~\textmu m,  50~\textmu m, 3 days}. This measurement
+will characterise proton emission in muon capture on titanium, which
+is a promising
+target option for future muon-electron conversion experiments.
