Measurement of the decay times of organic scintillators

Neutron yield measurements on a TMX endplug

“…It follows that the ion energy-decay time, T E , in the shots studied is in the range T E ~ 4 to 6 ms. This estimate is consis tent with T^g = 5.8 ms based on electron drag cooling at n e = 1.2 X 10" cm" 3 and T c = 137 eV, the parameters corresponding to the shot from which the data in Fig. 13 were obtained.…”

Tuning the decay time of liquid scintillators

“…Decay time characterization of liquid scintillators has been the main subject of numerous publications. 12,15,19,20 As already mentioned, having access to long-lived (i.e. 10 -100 ns) photoluminescence decay times in liquid media is not straightforward.…”

“…Various research programs were conducted to accelerate this decay time for fast timing applications, leading to ultra-fast liquids, 14 but to the best of our knowledge extending the decay time to longer values has only been barely studied. 15 Here in 15 all the liquid scintillators that have been tested are from Nuclear Enterprises and their formulation is proprietary. On the basis of the Authors' work, only three liquids display decay times higher than 10 ns: NE 321 (15.70 ns), NE 227 (17.02 ns) and NE 317 (20.21 ns).…”

Effect of low angle grain boundaries on detection characteristics of trans-stilbene crystals

“…The high-speed version for monophoton technique was adopted by Kirkbride et al [9]. Simple and equally precise way of measuring the decay time has been elucidated [10].…”
