摘要:

本文研究了α粒子和γ射线在液态氙中产生的闪烁与外加电场的关系。对于能量约为200 keV的后向散射伽马射线,发现闪烁光子的数量随着场强的增加而减少64+/-2%。因此,发现α粒子和γ射线之间的脉冲形状辨别能力随着场的增加而减小,但在较高场下保持非零。

英文摘要:

Scintillation produced in liquid xenon by alpha particles and gamma rays has been studied as a function of applied electric field. For back scattered gamma rays with energy of about 200 keV, the number of scintillation photons was found to decrease by 64+/-2% with increasing field strength. Consequently, the pulse shape discrimination power between alpha particles and gamma rays is found to reduce with increasing field, but remaining non-zero at higher fields.
