|
|---|
| 95 | // --------------------------------
|
|---|
| 96 | //
|
|---|
| 97 | // I. Introduction
|
|---|
| 98 | // ---------------
|
|---|
| 99 | // It is planned to take light calibration events (at a certain fixed frequency
|
|---|
| 100 | // lambda_calib) interlaced with cosmics events. The advantages of this
|
|---|
| 101 | // procedure are :
|
|---|
| 102 | //
|
|---|
| 103 | // - the pedestals, which would be determined from the cosmics, could be
|
|---|
| 104 | // used for both the calibration and the cosmics events
|
|---|
| 105 | //
|
|---|
| 106 | // - because calibration and cosmics events are taken quasi simultaneously,
|
|---|
| 107 | // rapid variations (in the order of a few minutes) of base lines and of the
|
|---|
| 108 | // photon/ADC conversion factors could be recognized and taken into account
|
|---|
| 109 | //
|
|---|
| 110 | // The effective observation time T_eff is defined as that time range, within
|
|---|
| 111 | // which the recorded number of events N_cosmics would be obtained under ideal
|
|---|
| 112 | // conditions (only cosmics, no dead time, no calibration events, ...).
|
|---|
| 113 | //
|
|---|
| 114 | // In the absence of calibration events the effective observation time can
|
|---|
| 115 | // be determined from the distribution of time differences 'dt' between
|
|---|
| 116 | // successive cosmics events (see first figure in the attached ps file).
|
|---|
| 117 | // The exponential slope 'lambda' of this distribution is the ideal cosmics
|
|---|
| 118 | // event rate. If 'N_cosmics' is the total number of recorded cosmics events,
|
|---|
| 119 | // T_eff is obtained by
|
|---|
| 120 | //
|
|---|
| 121 | // T_eff = N_cosmics / lambda
|
|---|
| 122 | //
|
|---|
| 123 | // In the case of a finite dead time 'dead', the distribution (for dt > dead) is
|
|---|
| 124 | // still exponential with the same slope 'lambda'. 'lambda' should be determined
|
|---|
| 125 | // in a region of 'dt' which is not affected by the dead time, i.e. at not too
|
|---|
| 126 | // low 'dt'.
|
|---|
| 127 | //
|
|---|
| 128 | //
|
|---|
| 129 | //
|
|---|
| 130 | // II. Problems in the presence of calibration events
|
|---|
| 131 | // --------------------------------------------------
|
|---|
| 132 | // If calibration events are taken interlaced with cosmics, and if the dead time
|
|---|
| 133 | // is negligible, the distribution of time differences 'dt' between cosmics can
|
|---|
| 134 | // be used for calculating the effective observation time, as if the calibration
|
|---|
| 135 | // events were not present.
|
|---|
| 136 | //
|
|---|
| 137 | // In the case of a non-negligible dead time 'dead', however, the distribution of
|
|---|
| 138 | // time differences between cosmics is distorted, because a cosmics event may be
|
|---|
| 139 | // lost due to the dead time after a calibration event. Even if the time
|
|---|
| 140 | // intervals are ignored which contain a calibration event,
|
|---|
| 141 | //
|
|---|
| 142 | //
|
|---|
| 143 | // ---|---------o--------|---------> t
|
|---|
| 144 | //
|
|---|
| 145 | // cosmics calib cosmics
|
|---|
| 146 | //
|
|---|
| 147 | // <----------------> <==== time interval to be ignored
|
|---|
| 148 | //
|
|---|
| 149 | //
|
|---|
| 150 | // the distribution of 'dt' is still distorted, because there would be no
|
|---|
| 151 | // 'dt' with dt > tau_calib = 1/lambda_calib. The distribution would also be
|
|---|
| 152 | // distorted in the region dt < tau_calib, due to calibration events occuring
|
|---|
| 153 | // shortly after cosmics events. As a result, the slope of the distribution of
|
|---|
| 154 | // 'dt' would not reflect the ideal cosmics event rate (see second figure; the
|
|---|
| 155 | // values assumed in the simulation are lambda = 200 Hz, lambda_calib = 50
|
|---|
| 156 | // Hz, dead = 0.001 sec, total time = 500 sec, number of generated cosmics
|
|---|
| 157 | // events = 100 000).
|
|---|
| 158 | //
|
|---|
| 159 | //
|
|---|
| 160 | // Note also that some calibration events will not be recorded due to the dead
|
|---|
| 161 | // time after a cosmics event.
|
|---|
| 162 | //
|
|---|
| 163 | //
|
|---|
| 164 | // III. Proposed procedures
|
|---|
| 165 | // ------------------------
|
|---|
| 166 | //
|
|---|
| 167 | // A) The ideal event rate 'lambda' may be calculated from the distribution of
|
|---|
| 168 | // the time difference 'dt_first' between a calibration event and the first
|
|---|
| 169 | // recorded cosmics event after the calibration event. In the region
|
|---|
| 170 | //
|
|---|
| 171 | // dead < dt_first < tau_calib
|
|---|
| 172 | //
|
|---|
| 173 | // the probability distribution of dt_first is given by
|
|---|
| 174 | //
|
|---|
| 175 | // p(dt_first) = c * exp(-lambda*dt_first)
|
|---|
| 176 | //
|
|---|
| 177 | // where c is a normalization constant. 'lambda' can be obtained by a simple
|
|---|
| 178 | // exponential fit to the experimental distribution of dt_first (see third
|
|---|
| 179 | // figure). The fit range should start well above the average value of the dead
|
|---|
| 180 | // time 'dead'.
|
|---|
| 181 | //
|
|---|
| 182 | //
|
|---|
| 183 | // B) One may consider those time intervals between recorded cosmics events, which
|
|---|
| 184 | // are completely contained in the region
|
|---|
| 185 | //
|
|---|
| 186 | // t_calib < t < t_calib + tau_calib
|
|---|
| 187 | //
|
|---|
| 188 | // where t_calib is the time of a recorded calibration event.
|
|---|
| 189 | //
|
|---|
| 190 | //
|
|---|
| 191 | // <--------------- tau_calib ----------->
|
|---|
| 192 | //
|
|---|
| 193 | //
|
|---|
| 194 | // 0 1 2 3 4 5 6 7 8 9 10
|
|---|
| 195 | // --|-o---|-|---|--|-|----|--|---|---|-|----o-|---|-|---------> t
|
|---|
| 196 | // ^ ^
|
|---|
| 197 | // | |
|
|---|
| 198 | // t_calib t_calib + tau_calib
|
|---|
| 199 | //
|
|---|
| 200 | //
|
|---|
| 201 | // In this example, of the time intervals 0 to 10 only the intervals 1 to 9
|
|---|
| 202 | // should be retained and plotted. The distribution of the length 'dt' of these
|
|---|
| 203 | // intervals in the region
|
|---|
| 204 | //
|
|---|
| 205 | // dead < dt < tau_calib
|
|---|
| 206 | //
|
|---|
| 207 | // is given by
|
|---|
| 208 | //
|
|---|
| 209 | // p(dt) = c * (tau_calib-dt-dead) * exp(-lambda*dt)
|
|---|
| 210 | //
|
|---|
| 211 | // A fit of this expression to the experimental distribution of 'dt' yields
|
|---|
| 212 | // 'lambda' (see fourth figure). For 'dead' an average value of the dead time
|
|---|
| 213 | // should be chosen, and the fit range should end well before dt = tau_calib-dead.
|
|---|
| 214 | //
|
|---|
| 215 | //
|
|---|
| 216 | // Method A has the advantage that the p(dt_first) does not depend on 'dead'.
|
|---|
| 217 | // 'dead' has to be considered when defining the fit range, both in method A and
|
|---|
| 218 | // in method B. In method B the event statistics is larger leading to a smaller
|
|---|
| 219 | // fitted error of 'lambda' than method A (see the figures).
|
|---|
| 220 | //
|
|---|
| 221 | //
|
|---|
| 222 | // The effective observation time is again obtained by
|
|---|
| 223 | //
|
|---|
| 224 | // T_eff = N_cosmics / lambda
|
|---|
| 225 | //
|
|---|
| 226 | // where N_cosmics is the total number of recorded cosmics events. Note that
|
|---|
| 227 | // N_cosmics is equal to
|
|---|
| 228 | //
|
|---|
| 229 | // N_cosmics = N_tot - N_calib
|
|---|
| 230 | //
|
|---|
| 231 | // where N_tot is the total number of recorded events (including the calibration
|
|---|
| 232 | // events) and N_calib is the number of recorded calibration events.
|
|---|
| 233 | //
|
|---|
| 234 | // Note that if time intervals are discarded for the determination of lambda,
|
|---|
| 235 | // the corresponding cosmics events need not and should not be discarded.
|
|---|
| 236 | //
|
|---|
| 237 | //
|
|---|
| 238 | // IV. Procedure if the calibration events are taken in bunches
|
|---|
| 239 | // ------------------------------------------------------------
|
|---|
| 240 | // In November 2004 the rate of calibration events is not constant. The events
|
|---|
| 241 | // are taken in 200 Hz bunches every second, such that the rate is 200 Hz for
|
|---|
| 242 | // 0.25 sec, followed by a gap of 0.75 sec. Then follows the next 200 Hz bunch.
|
|---|
| 243 | //
|
|---|
| 244 | // In this case it is proposed to consider for the calculation of 'lambda' only
|
|---|
| 245 | // the cosmics events within the gaps of 0.75 sec. For these cosmics events one
|
|---|
| 246 | // of the methods described in III. can be applied.
|
|---|
| 247 | //
|
|---|
| 248 | //
|
|---|
| 249 | // V. Alternative pocedure
|
|---|
| 250 | // -----------------------
|
|---|
| 251 | // The effective observation time can also be determined from the total
|
|---|
| 252 | // observation time and the total dead time. The latter is written out by the DAQ.
|
|---|
| 253 | // In this case it has to be made sure that the dead time is available in Mars
|
|---|
| 254 | // when the effective observation time is calculated.
|
|---|
| 255 | //
