摘要
相对论效应实验谱仪能便捷、准确地验证快速电子的能量与动量的相对论关系.本文利用这一仪器开展了两个综合性实验,分别对铝片和铝箔的厚度进行了测量,不仅可以加深学生对核物理实验技术和应用的理解,也做到了仪器设备一机多用,提高使用效益.
The relativistic effect experimental spectrometer can be used to verify the relativistic relationship conveniently and accurately between the energy and momentum of fast electrons.Two comprehensive experiments are carried out to measure the thickness of aluminum sheet and foil respectively.It can not only help students to understand the nuclear physics experimental technology and applications,but also achieve the multiple applications of instruments,and improve using efficiency.
