在核反应堆中，裂变碎片的β衰变是衰变热和反中微子通量的来源。虽然这些量对反应堆安全和我们对中微子物理的理解非常重要，但我们并不是很清楚。在对来自反应堆的衰变热和反中微子通量的估计中观察到差异的一个原因可能与Pandemonum效应有关。在Jyväskylä的JYFL工厂使用全吸收光谱仪(TAS)进行了新的测量，以避免这种影响。将介绍TAS技术的概述和2009年测量活动的初步结果。
In a nuclear reactor, theβdecay of fission fragments is at the origin of decay heat and antineutrino flux. These quantities are not well known while they are very important for reactor safety and for our understanding of neutrino physics. One reason for the discrepancies observed in the estimation of the decay heat and antineutrinos flux coming from reactors could be linked with the Pandemonium effect. New measurements have been performed at the JYFL facility of Jyväskylä with a Total Absorption Spectrometer (TAS) in order to circumvent this effect. An overview of the TAS technique and first results from the 2009 measurement campaign will be presented.
