摘要: 为提高高年级学生的实验动手能力和创新能力,激发他们对实验的兴趣和热情,我们开设了研究型的教学实验:CsI( Tl) 闪烁体探测器能量分辨率的研究. 该实验需要学生自己包装制作CsI( Tl) 探头,自己动手搭建测试平台并测量CsI( Tl)探头的能量分辨率. 整个实验最大限度地发挥了学生对实验的参与度及动手实验的机会. 经过2013—2015 年3 年的教学实践表明,该实验是一个适合高年级本科生的研究型实验.

Abstract: In order to improve the experimental and creative ability of the senior under grade students,and arouse their interest and enthusiasm in the physical experiments,a new research experiment,named “energy resolution of the CsI( Tl) scintillator detectors”is set up. The students should package and install the CsI ( Tl) detectors by themselves,build their own testing platform and then measure the energy resolution of CsI ( Tl) scintillator detectors made by themselves. This experiment provides many opportunities for the students to participate in and hands-on. It is found that this research experiment is suitable for the senior under - grade students via the teaching practice of three years from 2013 to 2015.

Key words: CsI( Tl) scintillator, energy resolution, package material, coupling material
