68 | // Preliminary description of the calibration in photons (email from 12/02/04)

69 | //
|
---|
70 | // Why calibrating in photons:
|
---|
71 | // ===========================
|
---|
72 | //
|
---|
73 | // At the Barcelona meeting in 2002, we decided to calibrate the camera in
|
---|
74 | // photons. This for the following reasons:
|
---|
75 | //
|
---|
76 | // * The physical quantity arriving at the camera are photons. This is
|
---|
77 | // the direct physical information from the air shower. The photons
|
---|
78 | // have a flux and a spectrum.
|
---|
79 | //
|
---|
80 | // * The photon fluxes depend mostly on the shower energy (with
|
---|
81 | // corrections deriving from the observation conditions), while the photon
|
---|
82 | // spectra depend mostly on the observation conditions: zenith angle,
|
---|
83 | // quality of the air, also the impact parameter of the shower.
|
---|
84 | //
|
---|
85 | // * The photomultiplier, in turn, has different response properties
|
---|
86 | // (quantum efficiencies) for photons of different colour. (Moreover,
|
---|
87 | // different pixels have slightly different quantum efficiencies).
|
---|
88 | // The resulting number of photo-electrons is then amplified (linearly)
|
---|
89 | // with respect to the photo-electron flux.
|
---|
90 | //
|
---|
91 | // * In the ideal case, one would like to disentagle the effects
|
---|
92 | // of the observation conditions from the primary particle energy (which
|
---|
93 | // one likes to measure). To do so, one needs:
|
---|
94 | //
|
---|
95 | // 1) A reliable calibration relating the FADC counts to the photo-electron
|
---|
96 | // flux -> This is accomplished with the F-Factor method.
|
---|
97 | //
|
---|
98 | // 2) A reliable calibration of the wavelength-dependent quantum efficiency
|
---|
99 | // -> This is accomplished with the combination of the three methods,
|
---|
100 | // together with QE-measurements performed by David in order to do
|
---|
101 | // the interpolation.
|
---|
102 | //
|
---|
103 | // 3) A reliable calibration of the observation conditions. This means:
|
---|
104 | // - Tracing the atmospheric conditions -> LIDAR
|
---|
105 | // - Tracing the observation zenith angle -> Drive System
|
---|
106 | // 4) Some knowlegde about the impact parameter:
|
---|
107 | // - This is the only part which cannot be accomplished well with a
|
---|
108 | // single telescope. We would thus need to convolute the spectrum
|
---|
109 | // over the distribution of impact parameters.
|
---|
110 | //
|
---|
111 | //
|
---|
112 | // How an ideal calibration would look like:
|
---|
113 | // =========================================
|
---|
114 | //
|
---|
115 | // We know from the combined PIN-Diode and Blind-Pixel Method the response of
|
---|
116 | // each pixel to well-measured light fluxes in three representative
|
---|
117 | // wavelengths (green, blue, UV). We also know the response to these light
|
---|
118 | // fluxes in photo-electrons. Thus, we can derive:
|
---|
119 | //
|
---|
120 | // - conversion factors to photo-electrons
|
---|
121 | // - conversion factors to photons in three wavelengths.
|
---|
122 | //
|
---|
123 | // Together with David's measurements and some MC-simulation, we should be
|
---|
124 | // able to derive tables for typical Cherenkov-photon spectra - convoluted
|
---|
125 | // with the impact parameters and depending on the athmospheric conditions
|
---|
126 | // and the zenith angle (the "outer parameters").
|
---|
127 | //
|
---|
128 | // From these tables we can create "calibration tables" containing some
|
---|
129 | // effective quantum efficiency depending on these outer parameters and which
|
---|
130 | // are different for each pixel.
|
---|
131 | //
|
---|
132 | // In an ideal MCalibrate, one would thus have to convert first the FADC
|
---|
133 | // slices to Photo-electrons and then, depending on the outer parameters,
|
---|
134 | // look up the effective quantum efficiency and get the mean number of
|
---|
135 | // photons which is then used for the further analysis.
|
---|
136 | //
|
---|
137 | // How the (first) MAGIC calibration should look like:
|
---|
138 | // ===================================================
|
---|
139 | //
|
---|
140 | // For the moment, we have only one reliable calibration method, although
|
---|
141 | // with very large systematic errors. This is the F-Factor method. Knowing
|
---|
142 | // that the light is uniform over the whole camera (which I would not at all
|
---|
143 | // guarantee in the case of the CT1 pulser), one could in principle already
|
---|
144 | // perform a relative calibration of the quantum efficiencies in the UV.
|
---|
145 | // However, the spread in QE at UV is about 10-15% (according to the plot
|
---|
146 | // that Abelardo sent around last time. The spread in photo-electrons is 15%
|
---|
147 | // for the inner pixels, but much larger (40%) for the outer ones.
|
---|
148 | //
|
---|
149 | // I'm not sure if we can already say that we have measured the relative
|
---|
150 | // difference in quantum efficiency for the inner pixels and produce a first
|
---|
151 | // QE-table for each pixel. To so, I would rather check in other wavelengths
|
---|
152 | // (which we can do in about one-two weeks when the optical transmission of
|
---|
153 | // the calibration trigger is installed).
|
---|
154 | //
|
---|
155 | // Thus, for the moment being, I would join Thomas proposal to calibrate in
|
---|
156 | // photo-electrons and apply one stupid average quantum efficiency for all
|
---|
157 | // pixels. This keeping in mind that we will have much preciser information
|
---|
158 | // in about one to two weeks.
|
---|
159 | //
|
---|
160 | //
|
---|
161 | // What MCalibrate should calculate and what should be stored:
|
---|
162 | // ===========================================================
|
---|
163 | //
|
---|
164 | // It is clear that in the end, MCerPhotEvt will store photons.
|
---|
165 | // MCalibrationCam stores the conversionfactors to photo-electrons and also
|
---|
166 | // some tables of how to apply the conversion to photons, given the outer
|
---|
167 | // parameters. This is not yet implemented and not even discussed.
|
---|
168 | //
|
---|
169 | // To start, I would suggest that we define the "average quantum efficiency"
|
---|
170 | // (maybe something like 25+-3%) and apply them equally to all
|
---|
171 | // photo-electrons. Later, this average factor can be easily replaced by a
|
---|
172 | // pixel-dependent factor and later by a (pixel-dependent) table.
