论文摘要
本文致力于模拟在Troitsk Nu-Mass实验中观察到的所谓捕获效应。效果是由衰减电子在无窗气体源中的磁陷阱以及这些电子的逐渐蒸发引起的。结果，与常规的tritium beta-spectrum电子一起，我们看到了最初被困在源中的其他电子，并以变化的能量逃脱了。蒸发电子的光谱非常特殊（单色初始电子几乎平坦），在实验中无法直接测量。因此，必须依靠模拟。同样，在其他磁陷阱的情况下，可能会观察到相同的效果。
This paper is dedicated to the simulation of the so-called trapping-effect observed in the Troitsk nu-mass experiment. The effect is caused by the magnetic trapping of decay electrons in the windowless gaseous tritium source and the gradual evaporation of those electrons. As a result, alongside regular tritium beta-spectrum electrons, we see additional electrons that are initially trapped in the source and escape it with changed energy. The spectrum of evaporated electrons is quite peculiar (almost flat for monochromatic initial electrons) and could not be directly measured in the experiment. So one has to rely on simulations. Also, it is possible that the same effect could be observed in other cases of magnetic traps.
