• Cosmic radiation is a naturally occurring ionising radiation that arises from outside the earth . it has two components , solar radiation from the sun and galactic radiation from outside the solar system . it primarily consists of particles such as protons , neutrons and a - particles
  宇宙辐射是一种源自地球以外自然产生的致电离辐射，由太阳辐射和太阳系以外的银河辐射组成，主要包含质子中子和粒子等微粒。
• 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。
