| 67 | // Preliminary description of the calibration in photons (email from 12/02/04)
|
|---|
| 68 | //
|
|---|
| 69 | // Why calibrating in photons:
|
|---|
| 70 | // ===========================
|
|---|
| 71 | //
|
|---|
| 72 | // At the Barcelona meeting in 2002, we decided to calibrate the camera in
|
|---|
| 73 | // photons. This for the following reasons:
|
|---|
| 74 | //
|
|---|
| 75 | // * The physical quantity arriving at the camera are photons. This is
|
|---|
| 76 | // the direct physical information from the air shower. The photons
|
|---|
| 77 | // have a flux and a spectrum.
|
|---|
| 78 | //
|
|---|
| 79 | // * The photon fluxes depend mostly on the shower energy (with
|
|---|
| 80 | // corrections deriving from the observation conditions), while the photon
|
|---|
| 81 | // spectra depend mostly on the observation conditions: zenith angle,
|
|---|
| 82 | // quality of the air, also the impact parameter of the shower.
|
|---|
| 83 | //
|
|---|
| 84 | // * The photomultiplier, in turn, has different response properties
|
|---|
| 85 | // (quantum efficiencies) for photons of different colour. (Moreover,
|
|---|
| 86 | // different pixels have slightly different quantum efficiencies).
|
|---|
| 87 | // The resulting number of photo-electrons is then amplified (linearly)
|
|---|
| 88 | // with respect to the photo-electron flux.
|
|---|
| 89 | //
|
|---|
| 90 | // * In the ideal case, one would like to disentagle the effects
|
|---|
| 91 | // of the observation conditions from the primary particle energy (which
|
|---|
| 92 | // one likes to measure). To do so, one needs:
|
|---|
| 93 | //
|
|---|
| 94 | // 1) A reliable calibration relating the FADC counts to the photo-electron
|
|---|
| 95 | // flux -> This is accomplished with the F-Factor method.
|
|---|
| 96 | //
|
|---|
| 97 | // 2) A reliable calibration of the wavelength-dependent quantum efficiency
|
|---|
| 98 | // -> This is accomplished with the combination of the three methods,
|
|---|
| 99 | // together with QE-measurements performed by David in order to do
|
|---|
| 100 | // the interpolation.
|
|---|
| 101 | //
|
|---|
| 102 | // 3) A reliable calibration of the observation conditions. This means:
|
|---|
| 103 | // - Tracing the atmospheric conditions -> LIDAR
|
|---|
| 104 | // - Tracing the observation zenith angle -> Drive System
|
|---|
| 105 | // 4) Some knowlegde about the impact parameter:
|
|---|
| 106 | // - This is the only part which cannot be accomplished well with a
|
|---|
| 107 | // single telescope. We would thus need to convolute the spectrum
|
|---|
| 108 | // over the distribution of impact parameters.
|
|---|
| 109 | //
|
|---|
| 110 | //
|
|---|
| 111 | // How an ideal calibration would look like:
|
|---|
| 112 | // =========================================
|
|---|
| 113 | //
|
|---|
| 114 | // We know from the combined PIN-Diode and Blind-Pixel Method the response of
|
|---|
| 115 | // each pixel to well-measured light fluxes in three representative
|
|---|
| 116 | // wavelengths (green, blue, UV). We also know the response to these light
|
|---|
| 117 | // fluxes in photo-electrons. Thus, we can derive:
|
|---|
| 118 | //
|
|---|
| 119 | // - conversion factors to photo-electrons
|
|---|
| 120 | // - conversion factors to photons in three wavelengths.
|
|---|
| 121 | //
|
|---|
| 122 | // Together with David's measurements and some MC-simulation, we should be
|
|---|
| 123 | // able to derive tables for typical Cherenkov-photon spectra - convoluted
|
|---|
| 124 | // with the impact parameters and depending on the athmospheric conditions
|
|---|
| 125 | // and the zenith angle (the "outer parameters").
|
|---|
| 126 | //
|
|---|
| 127 | // From these tables we can create "calibration tables" containing some
|
|---|
| 128 | // effective quantum efficiency depending on these outer parameters and which
|
|---|
| 129 | // are different for each pixel.
|
|---|
| 130 | //
|
|---|
| 131 | // In an ideal MCalibrate, one would thus have to convert first the FADC
|
|---|
| 132 | // slices to Photo-electrons and then, depending on the outer parameters,
|
|---|
| 133 | // look up the effective quantum efficiency and get the mean number of
|
|---|
| 134 | // photons which is then used for the further analysis.
|
|---|
| 135 | //
|
|---|
| 136 | // How the (first) MAGIC calibration should look like:
|
|---|
| 137 | // ===================================================
|
|---|
| 138 | //
|
|---|
| 139 | // For the moment, we have only one reliable calibration method, although
|
|---|
| 140 | // with very large systematic errors. This is the F-Factor method. Knowing
|
|---|
| 141 | // that the light is uniform over the whole camera (which I would not at all
|
|---|
| 142 | // guarantee in the case of the CT1 pulser), one could in principle already
|
|---|
| 143 | // perform a relative calibration of the quantum efficiencies in the UV.
|
|---|
| 144 | // However, the spread in QE at UV is about 10-15% (according to the plot
|
|---|
| 145 | // that Abelardo sent around last time. The spread in photo-electrons is 15%
|
|---|
| 146 | // for the inner pixels, but much larger (40%) for the outer ones.
|
|---|
| 147 | //
|
|---|
| 148 | // I'm not sure if we can already say that we have measured the relative
|
|---|
| 149 | // difference in quantum efficiency for the inner pixels and produce a first
|
|---|
| 150 | // QE-table for each pixel. To so, I would rather check in other wavelengths
|
|---|
| 151 | // (which we can do in about one-two weeks when the optical transmission of
|
|---|
| 152 | // the calibration trigger is installed).
|
|---|
| 153 | //
|
|---|
| 154 | // Thus, for the moment being, I would join Thomas proposal to calibrate in
|
|---|
| 155 | // photo-electrons and apply one stupid average quantum efficiency for all
|
|---|
| 156 | // pixels. This keeping in mind that we will have much preciser information
|
|---|
| 157 | // in about one to two weeks.
|
|---|
| 158 | //
|
|---|
| 159 | //
|
|---|
| 160 | // What MCalibrate should calculate and what should be stored:
|
|---|
| 161 | // ===========================================================
|
|---|
| 162 | //
|
|---|
| 163 | // It is clear that in the end, MCerPhotEvt will store photons.
|
|---|
| 164 | // MCalibrationCam stores the conversionfactors to photo-electrons and also
|
|---|
| 165 | // some tables of how to apply the conversion to photons, given the outer
|
|---|
| 166 | // parameters. This is not yet implemented and not even discussed.
|
|---|
| 167 | //
|
|---|
| 168 | // To start, I would suggest that we define the "average quantum efficiency"
|
|---|
| 169 | // (maybe something like 25+-3%) and apply them equally to all
|
|---|
| 170 | // photo-electrons. Later, this average factor can be easily replaced by a
|
|---|
| 171 | // pixel-dependent factor and later by a (pixel-dependent) table.
