analyse_Al2O3C_ITC: Al2O3 Irradiation Time Correction Analysis


The function provides a very particular analysis to correct the irradiation time while irradiating Al2O3:C chips in a luminescence reader.


analyse_Al2O3C_ITC(object, signal_integral = NULL, dose_points = c(2,
  4, 8, 12, 16), recordType = c("OSL (UVVIS)"), method_control = NULL,
  verbose = TRUE, plot = TRUE, ...)



'>RLum.Analysis or list (required): results obtained from the measurement. Alternatively a list of 'RLum.Analysis' objects can be provided to allow an automatic analysis.


numeric (optional): signal integral, used for the signal and the background. If nothing is provided the full range is used. Argument can be provided as list.


numeric (with default): vector with dose points, if dose points are repeated, only the general pattern needs to be provided. Default values follow the suggestions made by Kreutzer et al., 2018. Argument can be provided as list.


character (with default): input curve selection, which is passed to function get_RLum. To deactivate the automatic selection set the argument to NULL


list (optional): optional parameters to control the calculation. See details for further explanations


logical (with default): enable/disable verbose mode


logical (with default): enable/disable plot output


further arguments that can be passed to the plot output

Background: Due to their high dose sensitivity Al2O3:C chips are usually irradiated for only a very short duration or under the closed beta-source within a luminescence reader. However, due to its high dose sensitivity, during the movement towards the beta-source, the pellet already receives and non-negligible dose. Based on measurements following a protocol suggested by Kreutzer et al., 2018, a dose response curve is constructed and the intersection (absolute value) with the time axis is taken as real irradiation time.


To keep the generic argument list as clear as possible, arguments to allow a deeper control of the method are all preset with meaningful default parameters and can be handled using the argument method_control only, e.g., method_control = list(fit.method = "LIN"). Supported arguments are:

mode plot_GrowthCurve as in plot_GrowthCurve; sets the mode used for fitting
fit.method plot_GrowthCurve as in plot_GrowthCurve; sets the function applied for fitting
