实验研究了GSO(Ce)闪烁晶体在161 MeV能量范围内对质子的光输出响应。用392 MeV质子束对边长为43 mm的立方晶体进行了实验。在30~161 MeV范围内有很好的线性关系，在30 MeV以下有轻微的非线性。用停止质子确定了d L d E与E的关系式。利用该关系式进行的计算与质子穿透晶体的测量脉冲高度以及质子停止的脉冲高度相一致。对2英寸的NaI(Tl)晶体也进行了类似的测量。立方的。在0-122 MeV的质子能量范围内观察到较大的非线性。
An experimental study on GSO(Ce) scintillation crystals was made in terms of the light output response to proton in an energy range up to 161 MeV. The experiment was carried out for cubic crystals of 43 mm edge length by using a 392 MeV proton beam. A good linearity was observed between 30 and 161 MeV, and a slight non-linearity below 30 MeV. A relation of d L d E versus E was determined with stopping protons. A calculation using the relation has agreed with measured pulse heights of protons penetrating the crystal, as well as those of stopping protons. Similar measurements were made for NaI(Tl) crystals of 2 in. cubic. Rather large non-linearity was observed in the proton energy range 0–122 MeV.
