	Dead time = L1A/L1		Dead time = L1A/L1

		+	Erica Said
		+	L1 or Level 1 is the incoming trigger. In this case is the detector signal (or the AND, when there is a coincidende, of the 2 detector signals) used as a start.
		+	The L1A or Level 1 Accept is the signal coming from the VME CPU that tells to the rest of the electronics that it can read and accept trigger, because it is not busy processing the previous data.
		+
		+	My understand is: L1 is incoming triggers. L1A are those L1 that is accepeted (or executed).
		+
		+	So, L1A/L1 should be the live time.

	<math>\frac{\left . \frac{L1A}{L1}\right \|_{Beam on}}{\left .\frac{L1A}{L1} \right \|_{Beam off}} = \frac{0.03}{0.17} = \frac{1}{6} \Rightarrow </math> mutiply the beam on data by a factor of 6 and leave the beam off data alone		<math>\frac{\left . \frac{L1A}{L1}\right \|_{Beam on}}{\left .\frac{L1A}{L1} \right \|_{Beam off}} = \frac{0.03}{0.17} = \frac{1}{6} \Rightarrow </math> mutiply the beam on data by a factor of 6 and leave the beam off data alone
