根据能量刻度实验的结果，我们对四种带电粒子进行了测试，方法是首先计算粒子的总能量，确定该粒子所属的能区并计算e ，根据e一e方法来鉴别带电粒子的种类。 |
| 6. | The irradiation experimental results show that the resolution of thin detector e1 is higher than that of other thick detectors for ex - particles and protons detection . energy calibration for a - particles was completed with multiplication factor 1 / 3 . energy calibrations of a - particles in detector e1 and e1 , are 0 . 107 mev and 0 . 123 mev per channel , respectively
质子能量刻度采用1档，每道能量h约在0 . 0167mev道，但是在e _ 1探测器中的能量刻度随着能量的增加略有所下降，这是由于高能质子伴随有较多的核反应道对粒子探测产生了干扰，从而增加了在e _ 1探测器中的能量沉积道数，使得每道能量略有所下降，另一个因素可能是探测器厚度的不均匀性的影响，但这并不影响对粒子的鉴别。 |
| 7. | The energy calibration is more accuracy and almost constant with the injected energy of proton . however , the energy calibration in e1 detector has a slight decrease with increasing the energy of protons . the reasons are attributed to the non - uniformity in thickness and disturbing from surrounding r , b ray and secondary particles
