Dead-time (linearity) Correction for Photomultiplier tubes (PMT)

Description

Correct dead-time (also linearity) of PMT counts to avoid saturation effects, depending on pulse-pair-resolution of individual PMTs.

Usage

correct_PMTLinearity(object, PMT_pulse_pair_resolution = NULL)

Arguments

object	RLum.Analysis RLum.Data.Curve (required): object with records to correct; can be a list of such objects
PMT_pulse_pair_resolution	numeric (with default): pulse-pair resolution in ns. Values can be found on the PMT datasheets. If NULL nothing is done.

Details

We correct for count linearity using a well-known formula that can be found for example in the Hamamatsu Photomultiplier handbook (Hamamatsu Photonics K.K., 2017):

N = \frac{M}{1 - Mt}

where N (in s^{-1}) is the true count rate, M (in s^{-1}) the measured count rate, and t (in s) the pulse pair resolution.

Value

Returns the same type of object type as object.
