r6602 r6603 110 110 111 111 112 \subsection{Applicability for Different Sampling Speeds / No Pulse Shaping.}113 112 114 The current read-out system of the MAGIC telescope~\cite{Magic-DAQ} with 300~MSamples/s is relatively slow compared to the fast pulses of 115 about 2\,ns FWHM of Cherenkov pulses. 116 To acquire the pulse shape an artificial pulse shaping to about 6.5\,ns FWHM is used. Thereby also more night sky background light 117 is integrated which acts as noise. 118 119 For 2 ns FWHM fast pulses a 2 GSamples/s FADC provides at least 4 sampling points. This permits a reasonable reconstruction of the pulse shape. First prototype tests with fast digitization systems for MAGIC have been successfully conducted \cite{GSamlesFADC}. The signals have been reconstructed within the common MAGIC Mars software framework. 120 121 122 \subsection{CPU Requirements} 123 124 Depending on the reconstruction algorithm the signal reconstruction can take a significant amount of CPU time. 125 Especially the more sophisticated signal extractors can be time consuming which search for the position of the Cherenkov signals 126 in the recorded FADC time slices and perform a fit to these samples. At any case, the extractor should not be significantly slower than 127 the reading and writing routines of the MARS software. 128 129 Thus, for an online-analysis a different extraction algorithm might be chosen than for the final most accurate 130 reconstruction of the signals offline. 131 132 \subsection{Treatment of Calibration Pulses} 113 \subsection{Intrinsic Differences between Calibration and Cosmics Pulses} 133 114 134 115 The calibration pulse reconstruction sets two important constraints to the signal extractor: … … 144 125 \end{enumerate} 145 126 127 \subsection{Reconstruction Speed} 128 129 Depending on the reconstruction algorithm the signal reconstruction can take a significant amount of CPU time. 130 Especially the more sophisticated signal extractors can be time consuming which search for the position of the Cherenkov signals 131 in the recorded FADC time slices and perform a fit to these samples.
