decay time

[di′kā ‚tīm]
(physics)
The time taken by a quantity to decay to a stated fraction of its initial value; the fraction is commonly 1/ e. Also known as storage time (deprecated).

The scintillation decay time is one of the important properties for scintillation detectors, and is directly related to the timing resolution of radiation detectors.
Decay times of scintillator materials affect the time interval of signal formation and thus they are key factors for data taking rate in calorimeters.
As compared to excitation above bandgap, an increase of decay times is also observed for both cases as well as in helium atmosphere.
(b) Ratio of the characteristic times obtained from the analysis of the autocorrelation functions shown in (a) normalized by the initial decay time measured at t = 0h.
One of the factors which affects the overall uncertainty of the measurement is the fitting when calculating the decay time. Due to the shape of the logarithmic calibration curve, fitting imposes different uncertainties at different temperatures.
The hidden variable in time possibility first presented in [1] gives a deterministic approach that attempts to explain the distribution in decay time as a result of a compatible distribution in an additional internal property within the particles.
The decay time that match real reverberation environment is used and uniformly distributed sound absorption is assumed.
Both a long decay time and afterglow would reduce the possible rotation speed in CT imaging procedures, prolonging the examination time and reducing the picture quality as the patients have to breathe during the procedure and may also move for different reasons.
Figures 1 and 2 show the correlation function (g([tau])) as a function of decay time for [C.sub.12][E.sub.5] microemulsion mixed with PCL (M.W = 5000 and 10000).
Secondly, the features of coupled system, which include resonance frequency and modal decay time, are analyzed with different variables, including panel thickness, panel internal damping, and enclosure depth.
[12], who stated that the larger the value of decay time was, the better the afterglow properties were.
